Tignoolajiyada indhaha ee microwave Quantum

Quantummikrowave opticalfarsamada
Farsamada indhaha ee Microwavewaxay noqotay goob awood badan, isku darka faa'iidooyinka tignoolajiyada indhaha iyo microwave-ka ee farsamaynta calaamadaha, isgaarsiinta, dareenka iyo dhinacyo kale. Si kastaba ha noqotee, nidaamyada sawir-qaadista microwave-ka caadiga ah waxay wajahayaan xaddidaadyo muhiim ah, gaar ahaan marka la eego xajmiga iyo dareenka. Si looga gudbo caqabadahan, cilmi-baarayaashu waxay bilaabeen inay sahamiyaan quantum mikrowave photonics - goob cusub oo xiiso leh oo isku dhafan fikradaha tignoolajiyada tirada iyo mikrowave photonics.

Aasaaska tignoolajiyada indhaha ee quantum microwave
Xudunta u ah tignoolajiyada indhaha ee microwave-ka ee quantum waa in la beddelo muuqaalkii hore ee indhahasawirqaadegudahaisku xirka sawirka microwaveoo leh dareen-qaade sawir-qaade keliya oo-sare. Tani waxay u oggolaanaysaa nidaamka inuu ku shaqeeyo heerarka awoodda indhaha ee aadka u hooseeya, xitaa ilaa heerka hal sawir, halka sidoo kale ay suurtogal tahay inuu kordhiyo xawaaraha.
Hababka photon microwave quantum ee caadiga ah waxaa ka mid ah: 1. Ilaha sawir-kaliya (tusaale, leysarka la yareeyey 2.Modulator-ka elektarooniga ahsi loo codeeyo calaamadaha microwave/RF 3. Qayb ka shaqaynta signalka indhaha4. Qalabka sawir-qaade ee hal-abuurka ah (tus. Superconducting nanowire detectors) 5. Tirinta sawir-qaadista (TCSPC) ee wakhtiga ku xidhan
Jaantuska 1 wuxuu muujinayaa isbarbardhigga u dhexeeya isku xirka sawir-qaadista mikrowave-dhaqameedka iyo isku-xireyaasha sawir-qaadista microwave-ka ee quantum:

Farqiga ugu muhiimsani waa isticmaalka qalabka sawir-qaade ee hal-abuurka ah iyo qaybaha TCSPC halkii aad ka isticmaali lahayd photodiodes-xawaaraha sare leh. Tani waxay awood u siinaysaa in la ogaado calaamadaha aadka u liita, iyada oo la rajeynayo in la riixo xajmiga xajmiga ka baxsan xadka sawir-qaadayaasha dhaqameed.

Nidaamka ogaanshaha sawirka kaliya
Nidaamka ogaanshaha sawirka kaliya ayaa aad muhiim ugu ah nidaamyada photon microwave-ka ee quantum. Mabda'a shaqadu waa sida soo socota: 1. Calaamadaha kiciya xilliyeedka ee la mid ah calaamadda la cabbiray waxaa loo diraa moduleka TCSPC. 2. Midka kaliya ee sawir qaadaha ah wuxuu soo saaraa garaaca garaaca wadnaha oo ka dhigan sawir-qaadayaasha la ogaaday. 3. Cutubka TCSPC wuxuu cabbiraa farqiga wakhtiga u dhexeeya calaamada kiciya iyo sawir kasta oo la ogaado. 4. Dhawr wareeg oo kiciya ka dib, wakhtiga ogaanshaha histogram ayaa la aasaasay. 5. Histogram-ku waxa uu dib u dhisi karaa qaabka mawjadaha ee calaamadda asalka ah. Xisaab ahaan, waxa la tusi karaa in suurtogalnimada in sawir-qaadista lagu ogaado wakhti go'an ay la mid tahay awoodda indhaha ee wakhtigaas. Sidaa darteed, histogram-ka wakhtiga ogaanshaha ayaa si sax ah u matali kara qaabka mawjada ee calaamadda la cabbiray.

Faa'iidooyinka muhiimka ah ee tiknoolajiyada indhaha ee quantum microwave
Marka la barbar dhigo hababka dhaqameed ee mikrowaytka, sawir-qaadista mikrowave ee quantum waxay leedahay faa'iidooyin dhowr ah oo muhiim ah: 1. Dareen-sare oo aad u sarreeya: Wuxuu ogaadaa calaamadaha aad u daciifsan ilaa heerka photon-ka keliya. 2. Kordhinta bandwidth: kuma xaddidna xadhkaha xadhkaha sawir-qaadaha, kaliya waxa saameeya wakhtiga jitter-ka-baaraha hal sawir-qaade. 3. Faragelinta ka hortagga ee la xoojiyay: Dib-u-dhiska TCSPC waxay shaandheyn kartaa calaamadaha aan ku xirneyn kicinta. 4. Sawaxanka hoose: Ka fogow sawaxanka ay keento ogaanshaha iyo kordhinta korantada ee dhaqanka.
