在冰上裂解30min英文The ice cracked underfoot, a symphony of creaks and snaps echoing through the frozen expanse. Each step was a dance with the elements, a test of balance and trust in theslippery surface.The minutes ticked by, the cold biting through layers of clothing, the air sharp and crisp. The ice, once a solid barrier, now seemed fragile, a mere veil over the dark waters below.Glancing around, the landscape was a canvas of white, unblemished by human touch. It was a world of its own, a realm where the ice dictated the rules and the wind was the only constant.A sudden shift in the ice's song caught my attention. A new note, a deeper rumble, suggested the ice was not just breaking but transforming, reshaping the very ground upon which I stood.As the half-hour mark approached, the ice had become a living entity, its surface shifting and groaning in a rhythm that mirrored the heartbeat of the earth itself. It was a reminder of the power and beauty of nature, a dance of destruction and creation.The final minutes were a silent vigil, the ice settlinginto a new pattern, a testament to its resilience. It was a moment of reflection, a realization that even in the face of change, there is a constant, unyielding strength.The 30 minutes on the ice were a journey, a challenge, and a lesson in the impermanence of the world around us. As I left the ice, I carried with me a deeper appreciation for the forces that shape our world, and the delicate balance that sustains it.。
热辣滚烫英文插曲名字As we delve into the world of music, it is impossible not to notice the impact that certain songs have had on our lives. Some songs have be so iconic that they have transcended language barriers and cultural differences, bing universally recognized and loved. One such category of songs are those with fiery, passionate titles - songs that exude energy, intensity, and a sense of excitement. In this article, we will be exploring some of the most popular and well-known English-language songs with titles that can only be described as "hot" or "spicy."First up, we have the classic rock anthem "Hot Blooded" by Foreigner. Released in 1978, this song quickly became a hit, thanks to its catchy guitar riff, driving beat, and lyrics about an intense love affair. With lines like "I'm hot blooded, check it and see / I got a fever of a hundred and three," this song perfectly captures the feeling of beingpletely consumed by passion.Another iconic hot-themed song is "She's Got Legs" by ZZ Top. This bluesy rock tune, released in 1983, features a memorable guitar riff and lyrics about a woman with particularly attractive legs. The chorus, which repeats the phrase "She's got legs, and she knows how to use them," has be a staple of classic rock radio and remains a favorite among fans of the genre.For those who prefer something a bit more modern, there's "Firework" by Katy Perry. This pop hit, released in 2010, features upbeat, energetic instrumentation and lyrics about embracing one's individuality and shining bright like a firework. The chorus, which declares "Do you ever feel like a plastic bag? / Drifting through the wind, wanting to start again? / Do you ever feel, feel so paper-thin? / Like a house of cards, one blow from caving in?" speaks to the universal desire to break free from limitations and express oneself fully.If you're looking for something with a bit more edge, there's always "Burn" by Ellie Goulding. This electropop track, released in 2013, features soaring vocals and a pulsing beat that builds to an explosive chorus.

Bluetooth Low EnergyProduct Brief v2.0OverviewBluetooth version 4.0 introduced Bluetooth with low energy functionality. Bluetooth low energy technology allows for short bursts of long-range radio connections, making it ideal for applications that depend on long battery life and don’t need high throughput streaming data. Developers are now able to create sensors that can run on coin-cell batteries for months and even years. Bluetooth low energy technology is built on an entirely new development framework using GATT (Generic Attributes). Silicon Labs supports the latest version of the Bluetooth ® Core Specification, Bluetooth™ LE 5.4. This enables customers to claim compliance with the latest Bluetooth spec.Bluetooth Low Energy ArchitectureThe Bluetooth Low Energy architecture components are as follows: Physical Layer: Controls radio transmission/receiving.Link Layer: Defines packet structure, includes the state machine and radio control, and provides link layer-level encryption.HCI: A Host-to-Controller interface (HCI) standardizes communication between the controller and the host.L2CAP: Logical Link Control and Adaptation Protocol acts as a protocol multiplexer and handles segmentation and reassembly of packets. ATT: Attribute protocol provides means to transmit data between Bluetooth low energy devices.SM: Security Manager provides means for bonding devices, encrypting and decrypting data, and enabling device privacyGAP: Generic Access Profile layer provides means for Bluetooth low energy devices to advertise themselves or other devices, make device discovery, open and manage connections, and broadcast data.GATT: GATT is used to group individual attributes into logical services GATT also provides information about the attributes, that is, how they can be accessed and what security level is needed.Key Features of Silicon Labs Bluetooth Low Energy StackFeature BenefitCore FeaturesDirection finding, Periodic Advertising with Responses (PAwR), Encrypted Advertising Data (EAD),Advertisement Extensions, Periodic Advertising, LE secure connections, 2M PHY , Long Range, AFH, LE Privacy 1.2 (peripheral), LE packet length extensions, Accept List (central side), GATT, & GATT Caching Scalable AoA Scale to AoA to few hundred devices simultaneouslyCertificate Based Authentication and Pairing (CBAP) Use certificates to authenticate devices before provisioning, thus saving cost and time. Also, prevents counterfeit devices from being provisioned into the networkSilicon Labs Bluetooth stack supports three modes:Standalone mode: Bluetooth stack and the application run in an EFR32SoC or moduleNetwork Co-Processor mode: Bluetooth stack runs on the EFR32, and the application runs on a separate host MCU. API is exposed over a serial interface such as UART.Radio Co-Processor mode: Link layer of the Bluetooth stack runs on the EFR32, and the Host Layer of the stack, as well as the application runs on a separate host MCU or PC. Link Layer and Host Layer communicate via HCI.Technical ResourcesBluetooth Low Energy xG24 Technical Library Data Sheets, App Notes, and moreBluetooth Low Energy xG21 Technical Library Data Sheets, App Notes, and moreBluetooth Low Energy xG22 Technical Library Data Sheets, App Notes, and moreBluetooth Low Energy xG27 Data ShortBluetooth Low Energy API Documentation Bluetooth Low Energy API documentationSilicon Labs’ Bluetooth Low Energy HW supportHigh Performance device for Bluetooth LE and Bluetooth mesh applications thatrequire advance features and more Flash and RAMIndustry-leading, energyefficient device for Bluetooth LE applicationsOptimized for line-powered devices including LED bulbs, and gateways for Bluetooth LE and Bluetooth meshMost Battery Versatile SoC for Connected Health, Smart Home, Portable Products1536kB Flash 256kB RAM TX power 19.5dBm -105.7dBm @ 125kbps -97.6dBm @ 1Mbit/s -94.8dBm @ 2Mbit/s RX current 4.4mA @ 1MbpsTX current 5.0mA @ 0dBm1.3 µA Sleep current (16kB )Robust peripheral set AI/ML hardware accelerator Secure Vault High QFN40 5x5 (26) QFN48 6x6 (32)512kB Flash 32kB RAM TX power 6dBm -106.7dBm @ 125kbps -98.9dBm @ 1Mbit/s -96.2dBm @ 2Mbit/s RX current 3.6mA @ 1MbpsTX current 4.1mA @ 0dBm1.26µA Sleep current (16kB )Lowest Power Bluetooth LESecure Vault Mid QFN40 5x5 (26) QFN32 4x4 (18) TQFN32 4x4 (18)1024kB Flash 96kB RAM TX power 20dBm -104.9dBm @ 125kbps -97.5dBm @ 1Mbit/s -94.4dBm @ 2Mbit/s RX current 8.8mA @ 1MbpsTX current 9.3mA @ 0dBm+135 Junc.

a r X i v :q u a n t -ph/01413v12A pr21The breakdown flash of Silicon Avalance Photodiodes –backdoor for eavesdropper attacks?Christian Kurtsiefer 1,Patrick Zarda 2,Sonja Mayer 1,and Harald Weinfurter 1,21Sektion Physik,Ludwig-Maximilians-Universit¨a t,D-80799M¨u nchen,Germany 2Max-Planck-Insitut f¨u r Quantenoptik,D-85748Garching,Germany February 1,2008submitted to J.Mod.Opt.Abstract Silicon avalanche photodiodes are the most sensitive photodetectors in the visible to near infrared region.However,when they are used for single photon detection in a Geiger mode,they are known to emit light on the controlled breakdown used to detect a photoelectron.This fluorescence light might have serious impacts on experimental ap-plications like quantum cryptography or single-particle spectroscopy.We characterized the fluorescence behaviour of silicon avalanche photodiodes in the experimentally sim-ple passive quenching configuration and discuss implications for their use in quantum cryptography systems.1Introduction For a long time,silicon avalanche photodiodes (APD)have been used for single photon detection in the near-infrared region[1,2]because of their high quantum efficiency and low dark count rate.These properties are particularly important for quantum cryptography[3,4,5,6],where a huge yield of secure bits and a low signal/noise ratio is crucial.To obtain a single photon counting behaviour,the avalanche diode is operated in an all-or-nothing counting mode similar to the way Geiger detectors are used in nuclear physics for particle counting.In this so-called Geiger mode,the diode is reversely biased above the breakdown voltage such that a single photoelectron can generate a self-sustaining dis-charge.The discharge current is used as an indicator for the generation of a photoelectron and thus of an absorbed photon.Thereby,a timing accuracy better then 60ps has been achieved[7].It has been observed previously that the avalanche of charge carriers is accompanied by photon emission[8].Although this light emission is not very strong,in several single photon counting applications it may have serious impacts on the experiment.In quan-tum cryptography,for example,such a light emission might enable an external observer to gain information of a photo detection event on the receiver side,opening a possible eavesdropping back door to an otherwise secure communication channel.Another exper-imental situation in which this photoemission has to be considered are photon correlation measurements,as they are performed in single atom or molecule spectroscopy.In a typi-cal Hanburry-Brown–Twiss configuration,two photodetectors are looking onto a faint light source,and one has to ensure that light emitted in the breakdown flash of one photodiode is not causing artificial photo events in the second photodetector due to residual crosstalk between the two photodetectors[9,10,11].It is therefore important to know the photoe-mission characteristics of that breakdown photoemission to avoid crosstalk with the light1absorption emissionU sig-Figure 1:Operation of the APD in passive quenching mode.The diode (with a junction capacity C j and a parasitic capacity C p )is reverse biased via a high impedance quenching network R q above the breakdown voltage.At diode breakdown,the parasitic capacity C p discharges through the load resistance R m ,causing a voltage peak indicating the break-down.to be detected.In this paper,we describe our investigation of the temporal and spectral distribution as well as the absolute amount of light emitted during a detection event.2Photodiode operationA photodetection process is initiated by a photoelectron created after absorption of a photon in a reverse-biased pn -junction.This electron is accelerated into a highly doped region where an avalanche of charge carriers is triggered.In single photon counting mode,the bias voltage exceeds the breakdown voltage of the diode,meaning that once an avalanche has been triggered,it is self-sustaining as long as the external voltage exceeds the breakdown threshold.To avoid the thermal damage of the diode and to bring it back into a state ready for a subsequent photoelectron detection,the avalanche has to be quenched.This is done by lowering the reverse bias voltage across the diode for a certain time.After allowing all charge carriers to recombine and thus bringing the diode into an insulating state again,a full photodetection cycle is finished and the diode is ready for the next event.The usual configurations for that procedure are referred to passive and active quen-ching[12].In passive quenching,the diode is reverse-biased via a low-current network (e.g.a large resistor R q )such that the discharge current triggered by a photoelectron avalanche causes a voltage drop,reducing the voltage across the diode below the breakdown voltage (see figure 1).Then,the junction capacity C j has to be recharged again to the full reverse bias voltage.With usual passive quenching configurations,a recharge time on the order of a microsecond is achieved.To obtain a faster recharge and thereby a shorter dead time,active quenching techniques have to be used[7].Yet,the discharge current and thus the breakdown flash should not depend on the quenching configuration.In our experiments,we used an APD with an integrated two stage thermoelectric cooler,type C30902-SDTC from Perkin-Elmer.The diodes have a circular active area of 0.5mm diameter,and are accessible through a transparent window.They are mounted in modules together with a high voltage supply,a discriminator to generate standard NIM pulses and a temperature controller for the peltier element[13].We use a current limiting network instead of a quenching resistor,a measurement resistor of R m =100Ωand a reverse bias voltage of U bias =215V at a temperature of −25◦C,which is approximately 20V above the breakdown of the APD.According to the manufacturer,the diodes are supposed2-2.50. 2.5 5.7.510.12.515.02468101214[ns]t 1-t 2[m A ]I D p a i r c o u n t s t [ns](a)Figure 2:(a)Discharge current I D (T )of the avalanche photodiode during a breakdown cycle.(b)Histogram of coincidence events of both photodetectors.The left peak corre-sponds to photons emitted by diode 1seen by diode 2.Both peaks have an exponential decay with a time constant of 2.9ns.The asymmetry is due to the different magnification of the two diodes looking at each other.The shape of each peak resembles very much the discharge current behaviour.to show a single photon detection efficiency of up to 55%at a wavelength of 800nm[14],depending on operating conditions.The discharge current I D (t )we measured under these conditions is shown in figure 2a.It reflects an exponential decay,convoluted with a Gaussian distribution.From this mea-surement,we obtain a total charge ofQ D = T D (t )dt =64pCreleased during a diode breakdown.From that value,we deduce a parasitic capacity C p ofC p =QD /20V =3.2pF ,assuming that during breakdown,most of the current through R m is supplied by C p ,and not by the biasing network.3Absolute photoemission rateTo determine the amount of light emitted during a breakdown cycle,we used an optical arrangement sketched in figure 3.The active area of an APD module D 1is imaged with a lens f =50mm onto a second APD,D 2,with a demagnification of 2(corresponding to distances of g =150mm and b =75mm,respectively).This ensured that light emitted from all parts of the active area of diode D 1could reach the active area of D 2even for imperfect alignment.To define the solid angle of light collected from diode D 1,we used an aperture A with a diameter of 3mm (and 5mm in a second experiment)at a distance of d =123mm from the diode.The corresponding solid angles are Ω3=4.67·10−4sr and Ω5=1.3·10−3sr,respectively.The NIM pulses were sent both to PC-card based counters,and for timing analysis to a digital oscilloscope (LeCroy LC574A).Using a pair trigger feature together with an auxiliary delay line of 63ns,we collected coincidence events of the two detectors and his-togrammed their time differences t 1−t 2in an interval of -40ns to +60ns with a resolution of a few 100ps.To measure only the light emitted by the diode D 1,we lowered the ambient light such that D 1registered a count rate of r 1=2634cps.This is only moderately larger than the dark count rate (approximately 500cps)and ensures that scattering of external light to the second diode D 2is minimal.With the optical path open to the second diode and an aperture diameter of 3mm,we observe a count rate from diode D 2of r 2=731cps.Finally,only3Figure3:Setup to determine the integralfluorescence light.The active area of photodiode D1under investigation is imaged through a lens L onto a second photodiode D2,with an aperture A defining the solid angle seen of diode D1.Both diodes are operating in passive quenching Geiger mode.Their breakdown current is amplified,discriminated and sent to counters and an oscilloscope to investigate coincident events(The signal of D1is delayed by63ns).pair events are selected which ensures that only the properties of the breakdownflash were analysed.A histogram of time differences for double photo events is shown infigure2b.One can clearly recognize two peaks,the left one(t1−t2<60ns)corresponding to photo events registered in detector D2after a discharge of detector D1,and the right one corresponding to the reverse process.The asymmetry in the amplitudes of the two peaks can be explained by the asymmetry in the imaging optics,as the aperture is not located exactly at the lens position,and/or by a difference in the amount light produced by the two diodes.Each peak shows a rise time between1and2ns,and an exponential decay,probably following the discharge current of the diode.The distribution h(∆t)of each peak of time differences ∆t=t1−t2infigure2b has the same temporal pattern as the discharge current shown in figure2a.We modeled a higher resolution histogram of thefirst peak of h(∆t)by a convolution of an exponential decay with a time constantτand a Gaussian distribution with a variance σ.Using the model functionh(∆t)= Θ(∆t)·e−∆t/τ ⊗ e−∆t2/(2σ2) ,whereΘ(t)is a step function,we obtainfit values ofτ=2.75±0.07ns andσ=0.72±0.03ns.The actual shape of this distribution is determined by the discharge network.Integration over the pair distribution from t1−t2=20ns to62ns leads to a rate of n c=48.4±1s−1for photo events of detector D2induced by breakdown events of D1; the accidental count rate for that time window,n acc=r1r2·42ns=0.081s−14L2Figure4:Setup for measuring the breakdownflash spectrum.Light emitted form a diode D1is collimated through a lens L1with a focal length of f=150mm,dispersed through a diffraction grating G and detected after a fold mirror M with a second single photon counting APD D2after a collimation lens L2.The spectrum becomes visible in coincidence events between the two detectors D1and D2.is negligible.With the breakdown rate r1of D1and the captured solid angleΩ3,and assuming isotropic emission of thefluorescence light,we obtain a differential breakdown emission intensity ofd n L=39photons/srΩ3for each detected breakdown of the diode D1.From a similar measurement with an aperture diameter of5mm,we found a value of dn L/dΩ=43photons/sr.Within the accuracy of the alignment of the photodetectors and the assumption of isotropy of emission,these two values are compatible.However,these values do not contain a detection efficiencyηyet. Because this detection efficiency varies with the wavelength(and has a maximum of≈55% atλ≈820nm[14]),an estimate of total rate can only be given with a knowledge of the spectral distribution.4Spectral distribution of the breakdown emissionIn order to evaluate possible countermeasures in experiments sensitive to the breakdown light emission of an APD,we measured the spectral distribution of that light.Therefore, we used again a setup of two single photon counting APDs looking at each other,where we inserted a reflection grating as a tunablefilter in the optical path as shown infigure4. The active area of the diode under investigation,D1,was placed in the focal plane of a lens L1(f=150mm)to collimate the light emitted in a diode breakdown.Thefirst diffraction order of a blazed grating(1200lines/mm)was focused with another lens L2 onto the second APD,D2,acting as a photon detector.At a wavelength of632nm,we thereby obtain a wavelength resolution of approximately3.3nm FWHM;we adjusted the transmitted wavelength by turning the grating.Again,we identify photons from the breakdownflash in D1by looking for coincidences of detector events in D1and D2.We have chosen a coincidence time window ofτc=70ns after a breakdown of D1.In the experiment,we recorded the number of coincidence events, N c(λ),and events N1(λ),N2(λ)of the individual detectors for an integration time T.To obtain acceptable signal levels,we exposed detector D1to a raised level of background56008001000120000.20.40.60.81.[nm]λf l u ore s cen c ei nt e ns it y[a.u .]Figure 5:Normalized breakdown flash spectrum of the silicon avalanche photodiode.The emission is peaked around 850nm.The curve shown is obtained by subtracting the acci-dental coincidence rate from the raw measured coincidences and subsequent normalization to the count rate of the emitting diode.light,causing breakdown rates of N 1/T ≈17000...20000s −1.The corresponding count rate N 2/T of detector D 2was in the range of 5000...6000s −1.The number of coinci-dence events varied form 300to 1100counts over the recording periode.We correct for accidental coincidences and fluctuations in the breakdown rates of APD D 1,and obtain a normalized spectral distribution I (λ)from our experimental data using the expression:I (λ)=αN c (λ)−N 1(λ)·N 2(λ)·τc /TAlice BobFigure6:Possible eavesdropping attack to quantum cryptography system.A single photon carrying information on phase or polarization is sent from Alice to Bob without interception by Eve.However,Eve could have access to the photons emitted by Bob upon detection, and gain timing and/or polarization information of the detected photon.simply by looking at this photoemission,as sketched infigure6.It therefore has to be ensured that the amount of light leaking back to a possible eavesdropper is small in order to limit its knowledge on the outcome of the single particle measurement by Bob.To minimize the amount of light generated in thefirst place,the capacity C P should be reduced to a minimum.This technique,however,quickly reaches a limit with currently available photodiode packages.Another measure to reduce the emitted light would be the use of opticalfilters,blocking the spectral range of700-1000mn in which photoemission occurs.However,this technique is restricted to cases where the wavelength of the transmitted light is outside that range. This is the case with recently developed diamond-based single photon sources[9],or using shorter wavelength laser diode emission[15].For systems using laser diodes around850nm exploring an absorption minimum in opticalfibers[16],this technique would require narrow band interferencefilters around the emission wavelength of the diodes.Then,the possible leakage of information to an eavesdropper can be made negligibly small,too.Additionally,spatialfiltering may be used to block light propagating back the quantum channel.Assuming that the photoemission light is emitted without spatial coherence across the photo detection surface,and that light to be detected is coming out of a single spatial mode from an opticalfiber or an equivalent spatial modefilter in a free space arrangement, the back-propagating light is reduced.To estimate the fraction of light coupled back,wefirst consider the breakdownflash brilliance(i.e.,the number of photons emitted per surface area and solid angle)for each photon detection event.From our measurements,wefindB=dn LA D=2·10−3photons4=B·λ2a detection event.This value is independent of the detailed structure of the coupling optics as long as reciprocal optical elements are used.It is also only a lower limit obtainable with a similar photodetector,since we have not taken into account the quantum efficiency of the photo detector.To correct for the quantum efficiency and to estimate the real number of photons cou-pled back into the quantum channel,we use the measured spectral distribution I(λ)and a detection efficiencyη(λ)(i.e.,the product of photoelectron generation probability given by the manufacturer and the photoelectron detection efficiency of.55at20V above break-down)obtained from the manufacturer.Then,we numerically derive a correction factor given by the expression:β= I(λ)[7]S.Cova,A.Longoni,and A.Andreoni,1981,Rev.Sci.Instr.,52(3),408.[8]J.G.Rarity,Private communication.[9]C.Kurtsiefer,S.Mayer,P.Zarda,and H.Weinfurter,2000,Phys.Rev.Lett.,85,290.[10]W.E.Moerner,and M.Orrit,1999,Science,283,1670-1676[11]B.Lounis and W.E.Moerner,2000,Nature,407,491-493.[12]R.G.W.Brown,R.Jones,J.G.Rarity and K.D.Ridley,1987,Appl.Opt.,26,2383.[13]P.Zarda,1999,Quantenkryptographie–Ein Experiment im Vergleich.Diploma the-sis,University of Innsbruck,Austria.[14]Data sheet for the C30902-SDTC diode module,supplied by Perkin-Elmer,formerlyEG&G.[15]W.T.Buttler,R.J.Hughes,moreaux,G.L.Morgan,J.E.Nordholt,and C.G.Pe-terson,2000,Phys.Rev.Lett.,84,5652.[16]S.Chingga,P.Zarda,T.Jennewein,and H.Weinfurter,1999,Appl.Phys.B,69,389.[17]A.Muller,T.Herzog,B.Huttner,W.Tittel,H.Zbinden and N.Gisin,1997,Appl.Phys.Lett.,70,793-795.9。
