Fasahar gani ta na'urar microwave ta Quantum

Kwatantawana'urar gani ta microwavefasaha
Fasahar gani ta Microwaveya zama wani fanni mai ƙarfi, wanda ya haɗa fa'idodin fasahar gani da microwave a fannin sarrafa sigina, sadarwa, ji da sauran fannoni. Duk da haka, tsarin photonic na microwave na gargajiya yana fuskantar wasu manyan ƙuntatawa, musamman dangane da bandwidth da sensitivity. Don shawo kan waɗannan ƙalubalen, masu bincike sun fara bincika photonics na microwave quantum - wani sabon fanni mai ban sha'awa wanda ya haɗa ra'ayoyin fasahar quantum da microwave photonics.

Tushen fasahar gani ta na'urar microwave ta quantum
Babban fasahar gani ta na'urar hangen nesa ta quantum microwave ita ce maye gurbin fasahar gani ta gargajiyana'urar gano hotoa cikinHaɗin photon na microwavetare da na'urar gano hoto ta photon guda ɗaya mai yawan hankali. Wannan yana bawa tsarin damar aiki a ƙananan matakan ƙarfin gani, har ma da matakin photon guda ɗaya, yayin da kuma yana iya ƙara yawan bandwidth.
Tsarin photon na microwave na yau da kullun sun haɗa da: 1. Tushen photon guda ɗaya (misali, lasers masu ƙarancin haske 2.Mai daidaita na'urar lantarkidon rubuta siginar microwave/RF 3. Sashen sarrafa siginar gani4. Na'urorin gano photon guda ɗaya (misali na'urorin gano nanowire masu sarrafawa) 5. Na'urorin lantarki na ƙidayar photon guda ɗaya (TCSPC) waɗanda suka dogara da lokaci
Hoto na 1 yana nuna kwatancen tsakanin hanyoyin haɗin photon na microwave na gargajiya da hanyoyin haɗin photon na microwave na quantum:

Babban bambancin shine amfani da na'urorin gano haske guda ɗaya da na'urorin TCSPC maimakon na'urorin gano haske mai sauri. Wannan yana ba da damar gano sigina masu rauni sosai, yayin da ake fatan tura bandwidth fiye da iyakokin na'urorin gano haske na gargajiya.

Tsarin gano photon guda ɗaya
Tsarin gano photon guda ɗaya yana da matuƙar muhimmanci ga tsarin photon na microwave na quantum. Ka'idar aiki ita ce kamar haka: 1. Siginar kunna lokaci-lokaci da aka daidaita tare da siginar da aka auna ana aika ta zuwa sashin TCSPC. 2. Mai gano photon guda ɗaya yana fitar da jerin bugun jini waɗanda ke wakiltar photon da aka gano. 3. Tsarin TCSPC yana auna bambancin lokaci tsakanin siginar kunna da kowane photon da aka gano. 4. Bayan madaukai da yawa na kunna, ana kafa histogram ɗin lokacin ganowa. 5. Histogram ɗin na iya sake gina siginar juyawa ta asali. A lissafi, ana iya nuna cewa yuwuwar gano photon a wani lokaci ya yi daidai da ƙarfin gani a wancan lokacin. Saboda haka, histogram na lokacin ganowa zai iya wakiltar siginar juyawa ta daidai.

Muhimman fa'idodi na fasahar gani ta microwave quantum
Idan aka kwatanta da tsarin gani na microwave na gargajiya, na'urar daukar hoto ta quantum microwave tana da fa'idodi da yawa: 1. Babban ƙarfin ji: Tana gano sigina masu rauni sosai har zuwa matakin photon guda ɗaya. 2. Ƙara girman bandwidth: ba a iyakance ta da girman na'urar daukar hoto ba, sai dai girgizar lokaci na na'urar gano photon guda ɗaya ta shafa. 3. Ingantaccen hana tsangwama: Sake gina TCSPC na iya tace siginar da ba a kulle ta ga abin da ke haifar da shi ba. 4. Ƙarancin hayaniya: Guji hayaniyar da gano photoelectric na gargajiya da haɓakawa ke haifarwa.
