Daim ntawv thov ntawm QuantumMicrowave photonics tshuab
Kev Tiv Thaiv Cov Pauv Tsis Muaj Tsis Muaj
Ib qho ntawm cov kev siv peev xwm tshaj plaws ntawm Quantum microwave photonics technology yog qhov nrhiav tau ntawm microwave microwave / rf cim. Los ntawm kev siv tshuaj ntsuam xyuas ib zaug, cov kab ke no muaj ntau dua rhiab dua li cov txheej txheem ib txwm muaj. Piv txwv li, cov kws tshawb nrhiav tau pom cov qoj ib ce microwein uas tuaj yeem kuaj cov cim kom tsawg li -112.8 dbm yam tsis muaj hluav taws xob hluav taws xob. No ultra-siab rhiab ua rau nws zoo tagnrho rau cov ntawv thov xws li kev sib txuas lus tob.
Microwave photonicsTeebcim Ua
Quantum microwave ntau photosics kuj cuam tshuam ntau-bandwidth teeb liab ua haujlwm xws li theem hloov thiab lim. Los ntawm kev siv cov hluav taws xob disporive kho qhov muag, cov kws tshawb nrhiav pom qhov tseeb tias RF theem hloov mus txog 8 GHz RF lim cov bandwidths txog 8 GHz. Qhov tseem ceeb, cov yam ntxwv tseem ceeb no tau siv 3 GHZ Electronics, uas qhia tau tias kev ua yeeb yam tshaj cov kev txwv kev coj ua
Tsis yog-zaus zaus rau lub sij hawm qhia
Ib lub peev xwm nthuav tau hais txog ntawm Quantum entanglement yog daim qhia ntawm cov chaw tsis-hauv zos rau lub sijhawm. Cov txheej txheem no tuaj yeem qhia lub spectrum ntawm kev nruam-yoj pumped tag nrho-photon los rau ib lub sij hawm sau nyob rau thaj chaw deb. Lub kaw lus siv entangled photos nyob rau hauv uas ib nqaj hla dhau lub lim thiab lwm tus dhau los ntawm ib qho kev sib kis. Vim muaj cov kev vam khom lub photons entangled, lub hom spectral filting hom yog mapped tsis yog-hauv zos rau lub sijhawm sau.
Daim duab 1 qhia txog lub tswvyim no:
Hom no tuaj yeem ua tiav qhov ntsuas tau yooj yim uas tsis tau ntsuas ncaj qha rau kev ntsuas lub teeb ntsuas ncaj qha.
Compressed sensing
QuantumMicrowave OfterCov thev naus laus zis tseem muab txoj kev tshiab rau kev pom zoo ntawm cov cim dav dav. Siv cov randomness xam nyob rau hauv Quantum nyob rau hauv Quantum paub, cov kws tshawb nrhiav tau pom tias muaj QUANTUM lub cev muaj peev xwm kho tau ntawm10 GHz RFspectra. Lub kaw lus modulates RF teeb liab mus rau lub xeev polarization ntawm lub photon. Ib qho kev tshawb nrhiav ib leeg ntawm lub photo tau muab lub ntuj ntsuas kev ntsuas ntsuas kom haum rau kev hnov. Nyob rau hauv txoj kev no, lub teeb liab broadband tuaj yeem rov qab ntawm tus nqi yarnyquist ntsuas.
Quantum Kev Tshaj Tawm Tseem Ceeb
Ntxiv rau kev txhim kho microwave motals applicions kuj tseem txhim kho cov khoom sib txuas lus ntau, Quantum tseem ceeb faib (QKD). Cov kws tshawb nrhiav pom cov subcarrier multxxuantum tseem ceeb (SCM-QKD) los ntawm motionost photeator subcarrier mus rau Quantum Ntsiab Lus (QKD). Qhov no tso cai rau ntau cov khoom lag luam ywj siab ua kom kis tau ib lub nthwv dej ntawm lub teeb, yog li ua kom muaj kev ua tau zoo spectral zoo.
Daim duab 2 qhia cov ntsiab lus thiab sim ua los ntawm cov cab hlau no scm-QKD system:
Txawm hais tias Quantum microwave photonics thev naus laus zis yog cog lus, tseem muaj qee qhov kev cov nyom:
1. Siv cov peev txheej tiag tiag: Cov txheej txheem tam sim no yuav tsum muaj ntau lub sijhawm sib tsub zuj zus mus rau lub teeb liab.
2. Cov teeb meem cuam tshuam nrog tawg / ib qho cim: lub ntsiab lus ntawm kev tsim kho kom tsis txhob muaj kev ua kom tsis txhob rov ua cov cim.
3. Convert to a real microwave waveform: Additional steps are required to convert the reconstructed histogram into a usable waveform.
4. Cov yam ntxwv Ntaus: Kev kawm ntxiv txog kev coj cwj pwm ntawm quantum thiab microwave photonic cuab yeej hauv kev sib xyaw ua ke yog xav tau.
5. Kev sib xyaw: feem ntau cov nruab hnub no siv cov khoom sib txawv.
Txhawm rau hais txog cov kev cov nyom no thiab ua ntej daim teb, ntau tus neeg cog lus kev tshawb fawb yog tshwm sim:
1. Tsim cov txheej txheem tshiab rau kev ntsuas lub sijhawm tiag tiag thiab kev kuaj pom ib qho.
2. Tshawb nrhiav cov ntawv thov tshiab uas siv cov kev paub siab, xws li kua tshuaj microence ntsuas.
3. Kev txheeb xyuas qhov tseeb ntawm cov photons ua ke thiab hluav taws xob kom txo qis loj thiab nyuaj.
4. Kawm cov teeb meem txhim kho teeb pom kev zoo hauv kev sib xyaw ua ke microwee potcuits.
5. Sib txuas Quaq Microwave photing technology nrog lwm cov quaring cov noob thev naus laus zis.
