Amfani da kwantumfasahar microwave photonics

Gano siginar rauni
Ɗaya daga cikin mafi kyawun amfani da fasahar microwave photonics na quantum shine gano siginar microwave/RF mai rauni sosai. Ta hanyar amfani da gano photon guda ɗaya, waɗannan tsarin sun fi saurin amsawa fiye da hanyoyin gargajiya. Misali, masu binciken sun nuna tsarin microwave photonic na quantum wanda zai iya gano sigina ƙasa da -112.8 dBm ba tare da wani ƙara girman lantarki ba. Wannan yanayin rashin jin daɗi mai yawa ya sa ya dace da aikace-aikace kamar sadarwa mai zurfi ta sararin samaniya.

Na'urar daukar hoto ta Quantum microwave kuma tana aiwatar da ayyukan sarrafa sigina masu girman bandwidth kamar canjin lokaci da tacewa. Ta hanyar amfani da sinadarin gani mai watsewa da daidaita tsawon hasken, masu binciken sun nuna gaskiyar cewa matakin RF yana canzawa zuwa bandwidth na tacewa na RF 8GHz zuwa 8GHz. Abu mafi mahimmanci, duk waɗannan fasalulluka ana cimma su ta amfani da na'urorin lantarki na 3GHz, wanda ke nuna cewa aikin ya wuce iyakokin bandwidth na gargajiya.

Wani abu mai ban sha'awa da ke tattare da haɗakar ƙwayoyin halitta shine taswirar mitar da ba ta gida ba zuwa lokaci. Wannan dabarar za ta iya tsara bakan tushen photon guda ɗaya mai ci gaba da tura zuwa yankin lokaci a wani wuri mai nisa. Tsarin yana amfani da nau'ikan photon da aka haɗa inda ɗaya daga cikinsu ke wucewa ta matatar spectral yayin da ɗayan kuma ke wucewa ta cikin wani abu mai warwatsewa. Saboda dogaro da mitar photons da aka haɗa, yanayin tacewa na spectral yana nuna ba a gida ba zuwa yankin lokaci.

Ta amfani da bazuwar da ke tattare da gano kwantum, masu bincike sun nuna tsarin na'urar gano kwantum mai matsa lamba wanda zai iya murmurewaRF 10 GHzTsarin yana daidaita siginar RF zuwa yanayin rarrabuwar ƙwayoyin halitta na photon mai haɗin kai. Gano photon guda ɗaya sannan yana samar da ma'aunin ma'auni na halitta don matsewar ji. Ta wannan hanyar, ana iya dawo da siginar broadband a ƙimar samfurin Yarnyquist.

Rarraba maɓallan Kwatantawa
Baya ga inganta aikace-aikacen photonic na microwave na gargajiya, fasahar quantum kuma na iya inganta tsarin sadarwa na quantum kamar rarraba maɓallin quantum (QKD). Masu binciken sun nuna rarraba maɓallin quantum mai yawa (SCM-QKD) na subcarrier ta hanyar ninka maɓallin subcarrier na microwave photons zuwa tsarin rarraba maɓallin quantum (QKD). Wannan yana ba da damar watsa maɓallan quantum masu zaman kansu da yawa a kan tsawon haske ɗaya, ta haka yana ƙara ingancin spectral.
Siffa ta 2 tana nuna manufar da sakamakon gwaji na tsarin SCM-QKD mai ɗaukar kaya biyu:

Duk da cewa fasahar na'urar daukar hoto ta quantum microwave tana da kyau, akwai wasu ƙalubale:
1. Iyakance iya aiki a ainihin lokaci: Tsarin yanzu yana buƙatar lokaci mai yawa na tarawa don sake gina siginar.
2. Wahalar da ke tattare da fashewar sigina/sigina guda ɗaya: Yanayin kididdiga na sake ginawa yana iyakance amfaninsa ga sigina marasa maimaitawa.
3. A canza zuwa ainihin tsarin waveform na microwave: Ana buƙatar ƙarin matakai don canza tsarin histogram ɗin da aka sake ginawa zuwa tsarin waveform mai amfani.
4. Halayen Na'ura: Ana buƙatar ƙarin bincike kan halayen na'urorin photonic na quantum da microwave a cikin tsarin haɗin gwiwa.
5. Haɗawa: Yawancin tsarin a yau suna amfani da manyan abubuwan da ba a haɗa su ba.

1. Ƙirƙiri sabbin hanyoyi don sarrafa sigina a ainihin lokaci da kuma gano su sau ɗaya.
2. Bincika sabbin aikace-aikace waɗanda ke amfani da babban ƙarfin gani, kamar auna ma'aunin microsphere na ruwa.
3. A ci gaba da samar da sinadarin photons da electrons da aka haɗa domin rage girma da sarkakiya.
4. Yi nazarin ingantaccen hulɗar haske da abubuwa a cikin da'irorin photonic na microwave na quantum.
5. Haɗa fasahar photon na microwave na quantum tare da sauran fasahohin quantum masu tasowa.
