Aikace-aikace na adadifasahar photonics na microwave

Ganewar sigina mara ƙarfi
Ɗaya daga cikin mafi kyawun aikace-aikace na fasahar photonics microwave quantum shine gano siginar microwave/RF mai rauni sosai. Ta hanyar amfani da gano photon guda ɗaya, waɗannan tsarin sun fi kulawa fiye da hanyoyin gargajiya. Alal misali, masu bincike sun nuna tsarin tsarin photonic na microwave wanda zai iya gano sigina a matsayin ƙasa da -112.8 dBm ba tare da haɓakawa na lantarki ba. Wannan ƙwanƙwasa mai girman gaske yana sa ya dace don aikace-aikace kamar sadarwar sararin samaniya mai zurfi.

Microwave photonicssarrafa sigina
Quantum microwave photonics kuma yana aiwatar da ayyukan sarrafa sigina mai girma-bandwidth kamar canjin lokaci da tacewa. Ta amfani da ɓangarorin gani na gani da daidaita tsayin haske, masu binciken sun nuna gaskiyar cewa lokacin RF yana motsawa zuwa 8 GHz RF tace bandwidths har zuwa 8 GHz. Mahimmanci, waɗannan fasalulluka duk ana samun su ta amfani da na'urorin lantarki na 3 GHz, wanda ke nuna cewa aikin ya wuce iyakokin bandwidth na gargajiya.

Mitar da ba na gida ba zuwa taswirar lokaci
Ɗaya mai ban sha'awa mai ban sha'awa da aka samu ta hanyar haɗin ƙima shine taswirar mitar da ba na gida ba zuwa lokaci. Wannan fasaha na iya taswirar bakan na tushen hoto ɗaya mai ci gaba da zazzagewa zuwa yankin lokaci a wuri mai nisa. Tsarin yana amfani da nau'i-nau'i-nau'i-nau'i-nau'i na photon wanda katako guda ɗaya ya ratsa ta cikin tacewa, ɗayan kuma ya wuce ta wani abu mai tarwatsewa. Sakamakon dogaro da mitar na ƙulle-ƙulle na photon, yanayin tacewa na taswira ba na gida ba ne zuwa yankin lokaci.

Wannan hanya na iya samun sassauƙan ma'aunin gani ba tare da sarrafa tushen hasken da aka auna kai tsaye ba.

Matsa lamba
Quantummicrowave na ganifasahar kuma tana ba da sabuwar hanya don matsa lamba na siginar watsa labarai. Yin amfani da bazuwar da ke tattare da gano ƙididdigewa, masu bincike sun nuna tsarin ji na ƙididdigewa wanda zai iya murmurewa.10 GHz RFbakan gizo. Tsarin yana daidaita siginar RF zuwa yanayin polarization na madaidaicin photon. Gano hoto guda ɗaya sannan yana ba da ma'aunin ma'aunin bazuwar dabi'a don matsa lamba. Ta wannan hanyar, ana iya dawo da siginar faɗaɗa akan ƙimar samfurin Yarnyquist.

Rarraba maɓallin maɓalli
Baya ga haɓaka aikace-aikacen photonic na gargajiya na microwave, fasahar ƙididdigewa kuma na iya haɓaka tsarin sadarwa na ƙididdigewa kamar rarraba maɓalli na ƙididdigewa (QKD). Masu binciken sun nuna rarraba maɓalli na maɓalli na maɓalli na maɓalli (SCM-QKD) ta hanyar haɓaka mai ɗaukar hoto na microwave a kan tsarin rarraba maɓalli (QKD). Wannan yana ba da damar watsa maɓallan ƙididdige masu zaman kansu da yawa sama da tsayin haske guda ɗaya, ta haka yana ƙara ƙarfin gani.
Hoto 2 yana nuna ra'ayi da sakamakon gwaji na tsarin SCM-QKD mai ɗaukar kaya biyu:

Kodayake fasahar photonics na quantum microwave tana da alƙawarin, har yanzu akwai wasu ƙalubale:
1. Iyakantaccen iyawar lokaci na ainihi: Tsarin na yanzu yana buƙatar lokaci mai yawa don sake gina siginar.
2. Wahalar ma'amala da fashewa / sigina guda ɗaya: Halin ƙididdiga na sake ginawa yana iyakance ikon sa ga sigina marasa maimaitawa.
3. Canza zuwa na'urar motsin lantarki na gaske: Ana buƙatar ƙarin matakai don canza lissafin da aka sake ginawa zuwa tsarin igiyar ruwa mai amfani.
4. Halayen na'ura: Ana buƙatar ƙarin nazarin halayyar ƙididdiga da na'urorin photonic na microwave a cikin tsarin haɗin gwiwa.
5. Haɗin kai: Yawancin tsarin yau suna amfani da manyan abubuwan haɗin kai.

Don magance waɗannan ƙalubalen da ci gaba a fagen, ƙwararrun hanyoyin bincike masu ban sha'awa suna fitowa:
1. Haɓaka sababbin hanyoyin don sarrafa sigina na ainihi da ganowa guda ɗaya.
2. Bincika sababbin aikace-aikace waɗanda ke amfani da babban hankali, kamar ma'aunin microsphere na ruwa.
3. Bincika fahimtar hadedde photons da electrons don rage girma da rikitarwa.
4. Yi nazarin ingantaccen hulɗar al'amarin haske a cikin haɗaɗɗen da'irorin hoto na microwave quantum.
5. Haɗa fasahar photon quantum microwave tare da wasu fasahohin ƙididdiga masu tasowa.
