Quantum microwave Optical fasahar

Quantummicrowave na ganifasaha
Fasahar gani na Microwaveya zama fili mai ƙarfi, yana haɗa fa'idodin fasahar gani da injin microwave a cikin sarrafa sigina, sadarwa, ji da sauran fannoni. Koyaya, tsarin photonic na microwave na al'ada yana fuskantar wasu maɓalli na maɓalli, musamman dangane da bandwidth da hankali. Don shawo kan waɗannan ƙalubalen, masu bincike sun fara bincika ƙirar microwave na quantum - wani sabon filin mai ban sha'awa wanda ya haɗu da ra'ayoyin fasaha na ƙididdiga tare da microwave photonics.

Muhimman abubuwan fasaha na gani na microwave quantum
Babban jigon fasahar gani na microwave quantum shine maye gurbin na gani na gargajiyamai daukar hotoa cikinMicrowave photon mahadatare da babban ma'aunin hoto guda ɗaya mai ɗaukar hoto. Wannan yana ba da damar tsarin yin aiki a ƙananan matakan ƙarfin gani, har zuwa matakin hoto ɗaya, yayin da kuma mai yuwuwar haɓaka bandwidth.
Tsarukan photon microwave na yau da kullun sun haɗa da: 1. Maɓuɓɓugar hoto guda ɗaya (misali, Laser da aka rage 2.Electro-optic modulatordon shigar da siginar microwave/RF 3. Abubuwan sarrafa siginar gani4. Na'urorin gano photon guda ɗaya (misali Superconducting nanowire detectors) 5. Na'urorin lantarki waɗanda ke dogara da lokaci guda ɗaya na photon Counting (TCSPC)
Hoto na 1 yana nuna kwatance tsakanin hanyoyin haɗin hoto na microwave na al'ada da kuma hanyoyin haɗin hoton microwave quantum:

Bambancin maɓalli shine amfani da na'urorin gano photon guda ɗaya da na'urorin TCSPC maimakon photodiodes masu sauri. Wannan yana ba da damar gano sigina masu rauni sosai, yayin da da fatan tura bandwidth sama da iyakokin na'urar gano hoto na gargajiya.

Tsarin gano photon guda ɗaya
Tsarin gano photon guda ɗaya yana da mahimmanci sosai ga tsarin tsarin photon microwave quantum. Ka'idar aiki ita ce kamar haka: 1. Ana aika siginar faɗakarwa na lokaci-lokaci tare da siginar da aka auna zuwa tsarin TCSPC. 2. Mai gano photon guda ɗaya yana fitar da jerin nau'ikan bugun jini waɗanda ke wakiltar photon da aka gano. 3. Tsarin TCSPC yana auna bambancin lokaci tsakanin siginar jawo da kowane photon da aka gano. 4. Bayan madaukai masu faɗakarwa da yawa, an kafa lokacin gano histogram. 5. Histogram na iya sake gina siginar raƙuman ruwa na asali.Ta hanyar lissafi, ana iya nuna cewa yuwuwar gano photon a wani lokaci ya yi daidai da ƙarfin gani a lokacin. Don haka, histogram na lokacin ganowa na iya wakiltar siginar da aka auna daidai yadda raƙuman ruwa.

Babban fa'idodin fasahar gani na microwave quantum
Idan aka kwatanta da na'urorin gani na microwave na gargajiya, quantum microwave photonics yana da fa'idodi da yawa: 1. Maɗaukakiyar hankali: Yana gano sigina mara ƙarfi har zuwa matakin photon guda ɗaya. 2. Ƙarfafa bandwidth: ba'a iyakance ta hanyar bandwidth na mai binciken hoto ba, kawai ya shafi jitter lokaci na mai gano photon guda ɗaya. 3. Ingantaccen tsangwama: TCSPC sake ginawa na iya tace sigina waɗanda ba a kulle su ba. 4. Ƙananan amo: Guji hayaniyar da aka samu ta hanyar ganowa da haɓakawa na gargajiya.
