Kev siv quantummicrowave photonics technology
Tsis muaj teeb meem nrhiav pom
Ib qho kev cog lus zoo tshaj plaws ntawm quantum microwave photonics thev naus laus zis yog kev tshawb pom ntawm qhov tsis muaj zog microwave / RF teeb liab. Los ntawm kev siv ib qho kev tshawb pom photon, cov tshuab no muaj kev nkag siab ntau dua li cov txheej txheem ib txwm muaj. Piv txwv li, cov kws tshawb fawb tau ua kom pom lub tshuab hluav taws xob quantum microwave photonic uas tuaj yeem ntes cov teeb liab qis li -112.8 dBm yam tsis muaj hluav taws xob amplification. Qhov no ultra-siab rhiab heev ua rau nws zoo tagnrho rau kev siv xws li kev sib txuas lus sib sib zog nqus.
Microwave photonicsteeb liab ua
Quantum microwave photonics kuj siv high-bandwidth teeb liab ua haujlwm xws li theem hloov thiab lim. Los ntawm kev siv lub dispersive optical element thiab kho lub wavelength ntawm lub teeb, cov kws tshawb fawb tau pom qhov tseeb tias RF theem hloov mus txog 8 GHz RF filtering bandwidths mus txog 8 GHz. Qhov tseem ceeb, cov yam ntxwv no tau ua tiav tag nrho siv 3 GHz hluav taws xob, uas qhia tau hais tias qhov kev ua tau zoo tshaj qhov txwv bandwidth.
Non-local zaus rau lub sij hawm daim ntawv qhia
Ib qho kev muaj peev xwm nthuav tawm los ntawm quantum entanglement yog daim ntawv qhia ntawm cov tsis nyob hauv zos mus rau lub sijhawm. Cov txheej txheem no tuaj yeem ua daim duab qhia qhov spectrum ntawm qhov nruam-yoj ib leeg-photon qhov chaw mus rau lub sijhawm sau npe ntawm qhov chaw nyob deb. Lub kaw lus siv entangled photon khub nyob rau hauv uas ib tug beam kis tau los ntawm ib tug spectral lim thiab lwm yam kis tau los ntawm ib tug dispersive caij. Vim lub zaus dependence ntawm entangled photons, spectral filtering hom yog mapped tsis nyob rau hauv lub sij hawm sau.
Daim duab 1 qhia txog lub tswvyim no:
Txoj kev no tuaj yeem ua tiav qhov ntsuas tau yooj yim spectral yam tsis muaj qhov ncaj qha tswj qhov ntsuas lub teeb.
Compressed hnov
Quantummicrowave kho qhov muagthev naus laus zis kuj tseem muab txoj hauv kev tshiab rau compressed sensing ntawm broadband signals. Siv cov randomness uas muaj nyob rau hauv quantum nrhiav kom tau, cov kws tshawb fawb tau pom lub quantum compressed sensing system muaj peev xwm rov qab tau.10 GHz RFspectra. Lub kaw lus modulates RF teeb liab mus rau lub xeev polarization ntawm coherent photon. Kev tshawb pom ib leeg-photon ces muab ib qho kev ntsuas kev ntsuas ntuj tsim rau compressed sensing. Nyob rau hauv txoj kev no, lub teeb liab broadband tuaj yeem rov qab los ntawm Yarnyquist sampling tus nqi.
Quantum key faib tawm
Ntxiv rau kev txhim kho cov kev siv microwave photonic ib txwm muaj, quantum thev naus laus zis tuaj yeem txhim kho quantum kev sib txuas lus xws li quantum key faib (QKD). Cov kws tshawb fawb tau pom cov subcarrier multiplex quantum key distribution (SCM-QKD) los ntawm multiplexing microwave photons subcarrier mus rau quantum key distribution (QKD) system. Qhov no tso cai rau ntau tus yuam sij quantum ywj pheej kom xa mus rau ib qho wavelength ntawm lub teeb, yog li ua kom cov spectral efficiency.
Daim duab 2 qhia txog lub tswv yim thiab kev sim cov txiaj ntsig ntawm ob lub cab kuj SCM-QKD:
Txawm hais tias quantum microwave photonics thev naus laus zis tau cog lus, tseem muaj qee qhov kev sib tw:
1. Txwv tsis pub muaj peev xwm ntawm lub sijhawm tiag tiag: Lub kaw lus tam sim no yuav tsum tau siv sijhawm ntau los txhim kho lub teeb liab.
2. Teeb meem nyuaj nrog tawg / ib lub cim: Cov xwm txheej ntawm kev tsim kho tshiab txwv tsis pub nws siv tau rau cov cim tsis rov ua dua.
3. Hloov mus rau lub microwave tiag tiag waveform: Cov kauj ruam ntxiv yog yuav tsum tau hloov cov histogram reconstructed rau hauv ib tug usable waveform.
4. Cov yam ntxwv ntawm cov cuab yeej: Kev kawm ntxiv txog tus cwj pwm ntawm quantum thiab microwave photonic li hauv cov tshuab ua ke yog xav tau.
5. Kev sib xyaw ua ke: Feem ntau cov tshuab niaj hnub no siv cov khoom sib cais loj heev.
Txhawm rau daws cov teeb meem no thiab ua tiav hauv thaj chaw, ntau cov lus qhia kev tshawb fawb muaj txiaj ntsig tau tshwm sim:
1. Tsim cov txheej txheem tshiab rau kev ua cov teeb liab ntawm lub sijhawm tiag tiag thiab kev tshawb nrhiav ib leeg.
2. Tshawb nrhiav cov ntawv thov tshiab uas siv cov kev xav tau siab, xws li kev ntsuas cov kua microsphere.
3. Ua raws li kev ua tiav ntawm kev sib xyaw photons thiab electrons kom txo qhov loj thiab qhov nyuaj.
4. Kawm txog kev txhim kho lub teeb pom kev zoo hauv kev sib xyaw quantum microwave photonic circuits.
5. Ua ke quantum microwave photon technology nrog rau lwm cov quantum technologies.
