Kev siv tshuab quantum microwave optical

Quantummicrowave kho qhov muagthev naus laus zis
Kev siv tshuab microwave opticaltau dhau los ua ib qho chaw muaj zog, sib txuas cov txiaj ntsig ntawm kev siv tshuab optical thiab microwave hauv kev ua cov teeb liab, kev sib txuas lus, kev xav thiab lwm yam. Txawm li cas los xij, cov tshuab microwave photonic ib txwm ntsib qee qhov kev txwv tseem ceeb, tshwj xeeb tshaj yog hais txog bandwidth thiab kev rhiab heev. Txhawm rau kov yeej cov teeb meem no, cov kws tshawb fawb tab tom pib tshawb nrhiav quantum microwave photonics - ib qho chaw tshiab zoo siab uas sib txuas cov tswv yim ntawm quantum technology nrog microwave photonics.

Cov hauv paus ntawm quantum microwave optical technology
Lub hauv paus ntawm quantum microwave optical technology yog los hloov cov tsoos opticallub tshuab ntes duabnyob rau hauv lubqhov txuas ntawm microwave photonnrog lub tshuab nrhiav pom ib lub photon uas muaj kev rhiab heev. Qhov no tso cai rau lub kaw lus ua haujlwm ntawm qib zog optical qis heev, txawm tias mus txog qib ib lub photon, thaum tseem muaj peev xwm ua rau bandwidth nce ntxiv.
Cov tshuab photon quantum microwave feem ntau muaj xws li: 1. Cov chaw photon ib leeg (piv txwv li, attenuated lasers 2.Electro-optic modulatorrau kev sau cov teeb liab microwave/RF 3. Cov khoom siv ua cov teeb liab optical signal processing4. Cov khoom siv ntes photon ib leeg (piv txwv li Superconducting nanowire detectors) 5. Cov khoom siv hluav taws xob uas siv sijhawm ntev los suav cov photon ib leeg (TCSPC)
Daim Duab 1 qhia txog kev sib piv ntawm cov txuas microwave photon ib txwm muaj thiab cov txuas quantum microwave photon:

Qhov txawv tseem ceeb yog kev siv cov khoom siv photon detectors thiab TCSPC modules es tsis txhob siv cov photodiodes ceev ceev. Qhov no ua rau pom tau cov teeb liab tsis muaj zog heev, thiab vam tias yuav thawb cov bandwidth dhau qhov txwv ntawm cov khoom siv photodetectors ib txwm muaj.

Ib qho kev tshawb nrhiav photon ib zaug
Cov txheej txheem nrhiav pom ib lub photon yog qhov tseem ceeb heev rau cov kab ke quantum microwave photon. Lub hauv paus ntsiab lus ua haujlwm yog raws li nram no: 1. Lub teeb liab trigger uas sib dhos nrog lub teeb liab ntsuas tau xa mus rau TCSPC module. 2. Lub teeb liab ib lub photon detector tso tawm ntau lub pulses uas sawv cev rau cov photons uas tau ntes. 3. Lub TCSPC module ntsuas qhov sib txawv ntawm lub sijhawm ntawm lub teeb liab trigger thiab txhua lub photon uas tau ntes. 4. Tom qab ntau lub voj voog trigger, lub sijhawm nrhiav pom histogram tau tsim. 5. Lub histogram tuaj yeem rov tsim dua lub waveform ntawm lub teeb liab qub. Hauv lej, nws tuaj yeem pom tias qhov muaj feem yuav ntes tau photon ntawm lub sijhawm muab yog proportional rau lub zog optical ntawm lub sijhawm ntawd. Yog li ntawd, lub histogram ntawm lub sijhawm nrhiav pom tuaj yeem sawv cev rau lub waveform ntawm lub teeb liab ntsuas tau meej.

Cov txiaj ntsig tseem ceeb ntawm kev siv tshuab quantum microwave optical
Piv rau cov tshuab microwave optical ib txwm muaj, quantum microwave photonics muaj ntau qhov zoo tseem ceeb: 1. Ultra-high sensitivity: Nrhiav tau cov teeb liab tsis muaj zog heev mus txog rau theem photon ib leeg. 2. Bandwidth nce: tsis txwv los ntawm bandwidth ntawm lub photodetector, tsuas yog cuam tshuam los ntawm lub sijhawm jitter ntawm lub photon detector ib leeg. 3. Txhim kho kev tiv thaiv kev cuam tshuam: TCSPC reconstruction tuaj yeem lim tawm cov teeb liab uas tsis xauv rau lub trigger. 4. Suab nrov qis dua: Tsis txhob muaj suab nrov los ntawm kev tshawb nrhiav thiab amplification photoelectric ib txwm muaj.
