Quantummicrowave opticaliteknoloji
Itekhnoloji ye-microwave opticalibe yintsimi enamandla, edibanisa iingenelo zeteknoloji ye-optical kunye ne-microwave kwi-signal processing, unxibelelwano, ukuva kunye neminye imiba. Nangona kunjalo, iinkqubo eziqhelekileyo zeefotonic ze-microwave zijongene nemida ephambili, ngakumbi ngokwemiba ye-bandwidth kunye novakalelo. Ukoyisa le miceli mngeni, abaphandi baqala ukuphonononga i-quantum microwave photonics- intsimi entsha enomdla edibanisa itekhnoloji ye-quantum kunye neefotonic ze-microwave.

Iziseko zeteknoloji ye-quantum microwave optical
Undoqo wetekhnoloji ye-quantum microwave optical kukubuyisela i-optical yemveliifotodetectorkwimicrowave photon linkene-high-sensitivity ye-photon photodetector enye. Oku kuvumela inkqubo ukuba isebenze kumanqanaba asezantsi kakhulu optical amandla, ukuya kuthi ga kwinqanaba lefoton enye, ngelixa ikwanokwandisa i-bandwidth.
Iisistim eziqhelekileyo ze-quantum microwave photon ziquka: 1. Imithombo yefoton enye (umz., iilaser ezithotyiweyo 2.Imodyuli ye-Electro-opticyokufakwa kweekhowudi kwiisiginali zemicrowave/RF 3. Icandelo lokusetyenzwa kophawu4. Izixhobo zokujonga ifotoni enye (umzekelo, iSuperconducting nanowire detectors) 5. Ixesha elixhomekeke kwixesha lokubalwa kwefotoni enye (TCSPC) izixhobo zombane
Umzobo woku-1 ubonisa uthelekiso phakathi kwamakhonkco efoton e-microwave yemveli kunye namakhonkco efoton e-quantum microwave:

Umahluko obalulekileyo kukusetyenziswa kwe-photon detectors enye kunye neemodyuli ze-TCSPC endaweni yeefotodiodes zesantya esiphezulu. Oku kuvumela ukubonwa kwemiqondiso ebuthathaka kakhulu, ngelixa ngethemba ukutyhala i-bandwidth ngaphaya kwemida yeefoto zemveli.

Inkqubo yokufumanisa ifotoni enye
Iskimu sokufumanisa ifotoni enye sibaluleke kakhulu kwiinkqubo zefoton ze-microwave zequantum. Umgaqo wokusebenza umi ngolu hlobo lulandelayo: 1. Umqondiso we-periodic trigger ohambelana nomqondiso olinganisiweyo uthunyelwa kwimodyuli ye-TCSPC. 2. Isixhobo esinye se-photon detector sikhupha uluhlu lwee-pulses ezimele iifotoni ezichongiweyo. 3. Imodyuli ye-TCSPC ilinganisa umda wexesha phakathi kwesignali ye-trigger kunye ne-photon nganye efunyenweyo. 4. Emva kwee-loops ezininzi ze-trigger, ixesha lokufumanisa i-histogram liyasekwa. 5. I-histogram inokuvuselela i-waveform yesignali ye-original.Imathematika, inokuboniswa ukuba amathuba okufumana ifoton ngexesha elinikiweyo lilingana namandla optical ngelo xesha. Ke ngoko, i-histogram yexesha lokufumanisa inokumela ngokuchanekileyo i-waveform yesiginali elinganisiweyo.

Iinzuzo eziphambili zeteknoloji ye-quantum microwave optical
Xa kuthelekiswa neenkqubo zakwantu zemicrowave optical systems, iquantum microwave photonics ineenzuzo ezininzi eziphambili: 1. Uvakalelo oluphezulu kakhulu: Ibona imiqondiso ebuthathaka kakhulu ukuya kumgangatho wefoton enye. 2. Ukunyuka kwe-Bandwidth: akukhawulelwanga yi-bandwidth ye-photodetector, echaphazelekayo kuphela yi-jitter yexesha le-photon detector enye. 3. I-anti-interference ephuculweyo: Ukwakhiwa kwakhona kwe-TCSPC kunokucoca izibonakaliso ezingatshixwanga kwi-trigger. 4. Ingxolo esezantsi: Yiphephe ingxolo ebangelwa kukubona umbane wesintu kunye nokukhulisa.
