Tekinoroji ye optical ye quantum microwave

Quantummicrowave opticaltekinoroji
Tekinoroji yekuona ye microwaverave munda une simba, uchibatanidza zvakanakira tekinoroji ye optical neye microwave mukugadzirisa masaini, kutaurirana, kunzwa nezvimwe zvinhu. Zvisinei, masisitimu e microwave photonic akajairika anotarisana nezvimwe zvipingamupinyi zvakakosha, kunyanya maererano ne bandwidth uye sensitivity. Kuti vakunde matambudziko aya, vaongorori vari kutanga kuongorora quantum microwave photonics - munda mutsva unonakidza unosanganisa pfungwa dze quantum tekinoroji ne microwave photonics.

Nheyo dze tekinoroji ye quantum microwave optical
Chinangwa chikuru che quantum microwave optical tekinoroji ndechekutsiva optical yechinyakaremudziyo wekuona fotomulink ye microwave photonine photon photodetector ine simba guru. Izvi zvinobvumira sisitimu kushanda pamasimba e optical akaderera zvakanyanya, kunyangwe kusvika padanho re single-photon, ukuwo zvichigona kuwedzera bandwidth.
Masisitimu e quantum microwave photon akajairika anosanganisira: 1. Manyuko e single-photon (semuenzaniso, ma lasers akaonda 2.Modulator yeElectro-opticyekunyora masaini e microwave/RF 3. Chikamu chekugadzirisa masaini e optical 4. Zvishandiso zve photon imwe chete (semuenzaniso, zvinoongorora nanowire zvinoshandisa Superconducting) 5. Zvishandiso zvemagetsi zve single photon Counting (TCSPC) zvinoenderana nenguva
Mufananidzo 1 unoratidza kuenzanisa pakati pezvisungo zvema microwave photon zvechinyakare nezvisungo zvema microwave photon zve quantum:

Musiyano mukuru ndewekushandiswa kwema single photon detectors nema TCSPC modules pachinzvimbo chema high-speed photodiodes. Izvi zvinoita kuti zviratidzo zvisashande zvakanaka, ukuwo zvichitarisira kuti bandwidth ipfuure miganhu yema photodetectors echinyakare.

Chirongwa chekuona photon imwe chete
Chirongwa chekuona photon chimwe chete chakakosha zvikuru kune masisitimu e quantum microwave photon. Nheyo yekushanda ndeiyi inotevera: 1. Chiratidzo che periodic trigger chakabatana nechiratidzo chakayerwa chinotumirwa kuTCSPC module. 2. Chinoongorora photon chimwe chete chinoburitsa ma pulses anomiririra ma photon akaonekwa. 3. Module yeTCSPC inoyera musiyano wenguva pakati pechiratidzo che trigger ne photon yega yega yakaonekwa. 4. Mushure mezvirongi zvakawanda zve trigger, histogram yenguva yekuona inosimbiswa. 5. Histogram inogona kugadzirazve waveform yechiratidzo chekutanga. Pamasvomhu, zvinogona kuratidzwa kuti mukana wekuona photon panguva yakatarwa unoenderana nesimba re optical panguva iyoyo. Nokudaro, histogram yenguva yekuona inogona kuratidza nemazvo waveform yechiratidzo chakayerwa.

Mabhenefiti makuru e quantum microwave optical technology
Zvichienzaniswa nemaitiro echinyakare e microwave optical, quantum microwave photonics ine zvakanakira zvakawanda: 1. Kunzwa kwakanyanya: Inoona masaini asina simba zvakanyanya kusvika padanho re single photon. 2. Kuwedzera kwebandwidth: hakuganhurirwi nebandwidth ye photodetector, inongokanganiswa chete ne timing jitter ye single photon detector. 3. Kudzivirira kupindira kwakawedzerwa: Kugadziriswa kweTCSPC kunogona kusefa masaini asina kuvharirwa kune trigger. 4. Ruzha rwakaderera: Dzivisa ruzha rwunokonzerwa ne photoelectric detection yechinyakare uye amplification.
