I-Quantumi-microwave opticalubuchwepheshe
Itekhnoloji ye-optical ye-microwaveiye yaba yintsimi enamandla, idibanisa iingenelo zobuchwepheshe be-optical kunye ne-microwave ekucutshungulweni kwemiqondiso, unxibelelwano, ukuva kunye nezinye iinkalo. Nangona kunjalo, iinkqubo ze-microwave photonic eziqhelekileyo zijongene nemida ethile ebalulekileyo, ngakumbi ngokubhekiselele kwi-bandwidth kunye novakalelo. Ukuze boyise le mingeni, abaphandi baqala ukuphonononga i-quantum microwave photonics - intsimi entsha enomdla edibanisa iingcamango zobuchwepheshe be-quantum kunye ne-microwave photonics.

Iziseko zobuchwepheshe be-quantum microwave optical
Eyona nto iphambili kwitekhnoloji ye-optical ye-quantum microwave kukuthatha indawo ye-optical yendabukoisixhobo sokubona iifotokwiikhonkco le-photon ye-microwaveene-photon photon enye enovakalelo oluphezulu. Oku kuvumela inkqubo ukuba isebenze kumanqanaba amandla e-optical aphantsi kakhulu, kwanakwinqanaba le-photon enye, ngelixa inokwandisa i-bandwidth.
Iinkqubo ze-photon ze-microwave eziqhelekileyo ze-quantum ziquka: 1. Imithombo ye-photon enye (umz., ii-laser ezincitshisiweyo 2.Imodulator ye-electro-opticzokufaka ikhowudi kwiimpawu ze-microwave/RF 3. Icandelo lokucubungula isignali ye-optical 4. Izixhobo zokufumanisa i-photon enye (umz. Izixhobo zokufumanisa i-nanowire ezisebenzisa i-Superconducting) 5. Izixhobo ze-elektroniki ze-single photon Counting (TCSPC) ezixhomekeke kwixesha
Umfanekiso 1 ubonisa uthelekiso phakathi kweekhonkco ze-photon ze-microwave zemveli kunye neekhonkco ze-photon ze-microwave ze-quantum:

Umahluko ophambili kukusetyenziswa kwee-single photon detectors kunye nee-TCSPC modules endaweni yee-photodiodes ezikhawulezayo. Oku kwenza kube lula ukubona iimpawu ezibuthathaka kakhulu, ngelixa ngethemba lokuba i-bandwidth idlula imida yee-photodetectors zemveli.

Inkqubo yokubona i-photon enye
Inkqubo yokubona i-photon enye ibaluleke kakhulu kwiinkqubo ze-quantum microwave photon. Umgaqo wokusebenza ngolu hlobo lulandelayo: 1. Isignali ye-trigger yexesha elijikelezayo ehambelana nesignali elinganisiweyo ithunyelwa kwimodyuli ye-TCSPC. 2. I-single photon detector ikhupha uthotho lwee-pulses ezimele ii-photon ezifunyenweyo. 3. Imodyuli ye-TCSPC ilinganisa umahluko wexesha phakathi kwesignali ye-trigger kunye ne-photon nganye efunyenweyo. 4. Emva kwee-loops ezininzi ze-trigger, i-histogram yexesha lokufumanisa iyasekwa. 5. I-histogram inokuphinda yakhe i-waveform yesignali yokuqala. Ngokwezibalo, kunokuboniswa ukuba amathuba okufumana i-photon ngexesha elithile ahambelana namandla okukhanya ngelo xesha. Ke ngoko, i-histogram yexesha lokufumanisa inokumela ngokuchanekileyo i-waveform yesignali elinganisiweyo.

Iingenelo eziphambili zobuchwepheshe be-quantum microwave optical
Xa kuthelekiswa neenkqubo ze-microwave optical zemveli, i-quantum microwave photonics ineenzuzo ezininzi ezibalulekileyo: 1. Uvakalelo oluphezulu kakhulu: Ibona imiqondiso ebuthathaka kakhulu ukuya kwinqanaba le-single photon. 2. Ukwanda kwe-bandwidth: akuthintelwanga yi-bandwidth ye-photodetector, kodwa ichaphazeleka kuphela yi-timing jitter ye-single photon detector. 3. Ulwahlulo oluphuculweyo: Ukwakhiwa kwakhona kwe-TCSPC kunokucoca imiqondiso engatshixwanga kwi-trigger. 4. Ingxolo ephantsi: Kuphephe ingxolo ebangelwa kukufunyanwa kwe-photoelectric yendabuko kunye nokwandiswa kwayo.
