Quantum microwave optical technology

Quantummicrowave kho qhov muagtshuab
Microwave optical technologytau dhau los ua ib thaj chaw muaj zog, sib txuas cov txiaj ntsig zoo ntawm optical thiab microwave technology hauv kev teeb tsa, kev sib txuas lus, kev paub thiab lwm yam. Txawm li cas los xij, cov txheej txheem microwave photonic tau ntsib qee qhov kev txwv tseem ceeb, tshwj xeeb tshaj yog hais txog bandwidth thiab rhiab heev. Txhawm rau kov yeej cov teeb meem no, cov kws tshawb fawb tab tom pib tshawb nrhiav quantum microwave photonics - qhov chaw tshiab zoo siab uas muab cov ntsiab lus ntawm quantum technology nrog microwave photonics.

Lub hauv paus ntawm quantum microwave optical technology
Lub hauv paus ntawm quantum microwave optical technology yog los hloov cov tsoos kho qhov muagphotodetectorhauvmicrowave photon linknrog lub siab-rhiab heev ib photon photodetector. Qhov no tso cai rau lub kaw lus ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob kho qhov muag, txawm tias mus rau theem ib-photon, thaum tseem muaj peev xwm nce bandwidth.
Cov txheej txheem quantum microwave photon muaj xws li: 1. Ib leeg-photon qhov chaw (xws li, attenuated lasers 2.Electro-optic modulatorrau encoding microwave/RF signals 3. Optical signal processing component4. Tib photon detectors (xws li Superconducting nanowire detectors) 5. Lub sij hawm nyob ntawm ib leeg photon suav (TCSPC) cov khoom siv hluav taws xob
Daim duab 1 qhia txog kev sib piv ntawm ib txwm siv microwave photon txuas thiab quantum microwave photon txuas:

Qhov sib txawv tseem ceeb yog kev siv ib qho photon detectors thiab TCSPC modules es tsis txhob siv high-speed photodiodes. Qhov no ua rau kev tshawb pom ntawm cov teeb liab tsis tshua muaj zog, thaum cia siab tias yuav thawb lub bandwidth dhau qhov txwv ntawm cov duab thaij duab ib txwm muaj.

Ib qho kev tshawb pom photon
Txoj kev tshawb nrhiav ib qho photon tseem ceeb heev rau quantum microwave photon systems. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog raws li hauv qab no: 1. Lub sij hawm ua kom lub teeb liab synchronized nrog cov teeb liab ntsuas raug xa mus rau TCSPC module. 2. Ib qho photon detector outputs series ntawm pulses uas sawv cev rau qhov kuaj pom photons. 3. TCSPC module ntsuas lub sij hawm sib txawv ntawm lub teeb liab teeb liab thiab txhua qhov pom photon. 4. Tom qab ob peb lub voj voog, lub sij hawm tshawb pom histogram raug tsim. 5. Lub histogram tuaj yeem tsim kho lub nthwv dej ntawm qhov qub teeb liab.Mathematically, nws tuaj yeem pom tau tias qhov tshwm sim ntawm kev kuaj pom photon ntawm ib lub sijhawm yog proportional rau lub zog kho qhov muag thaum lub sijhawm ntawd. Yog li ntawd, lub histogram ntawm lub sij hawm nrhiav kom tau tseeb yog sawv cev rau lub waveform ntawm lub teeb liab ntsuas.

Qhov zoo ntawm quantum microwave optical technology
Piv rau cov txheej txheem microwave kho qhov muag, quantum microwave photonics muaj ntau yam zoo: 1. Ultra-siab rhiab heev: Tshawb xyuas cov teeb liab tsis tshua muaj zog mus rau theem ib qho photon. 2. Bandwidth nce: tsis txwv los ntawm bandwidth ntawm lub photodetector, tsuas yog cuam tshuam los ntawm lub sij hawm jitter ntawm ib tug photon detector. 3. Txhim khu kev tiv thaiv kev cuam tshuam: TCSPC rov tsim kho tuaj yeem lim tawm cov cim tsis raug kaw rau qhov tshwm sim. 4. Cov suab nrov qis: Tsis txhob muaj lub suab nrov los ntawm kev kuaj pom cov duab hluav taws xob thiab ua kom nrov nrov.
