Quantum microwave optical tekinoroji

Quantummicrowave Opticalteknolojia
Microwave optical tekinorojiyave munda une simba, uchibatanidza zvakanakira optical uye microwave tekinoroji mukugadzirisa zviratidzo, kutaurirana, kunzwa uye zvimwe zvinhu. Nekudaro, akajairwa microwave photonic masisitimu anotarisana nemimwe mipimo yakakosha, kunyanya maererano nebandwidth uye kunzwa. Kuti vakunde matambudziko aya, vaongorori vari kutanga kuongorora quantum microwave photonics - inonakidza munda mutsva unosanganisa pfungwa dzequantum tekinoroji nemicrowave photonics.

Zvinokosha zve quantum microwave optical tekinoroji
Iyo yakakosha ye quantum microwave optical tekinoroji ndeyekutsiva yechinyakare opticalphotodetectormumicrowave photon linkine high-sensitivity imwe photon photodetector. Izvi zvinobvumira sisitimu kuti ishande payakanyanya kuderera optical simba mazinga, kunyangwe pasi kusvika kune imwe-photon level, ukuwo ichigona kuwedzera bandwidth.
Yakajairika quantum microwave photon masisitimu anosanganisira: 1. Single-photon masosi (semuenzaniso, attenuated lasers 2.Electro-optic modulatorye encoding microwave/RF zviratidzo 3. Optical chiratidzo chekugadzirisa chikamu4. Ma detectors ephoton ega (eg Superconducting nanowire detectors) 5. Nguva inoenderana ne single photon Counting (TCSPC) midziyo yemagetsi
Mufananidzo 1 unoratidza kuenzanisa pakati pechinyakare microwave photon links uye quantum microwave photon links:

Musiyano wakakosha ndiko kushandiswa kweimwe chete photon detectors uye TCSPC modules panzvimbo yepamusoro-speed photodiodes. Izvi zvinogonesa kuwonekwa kwemasaini asina kusimba zvakanyanya, uku uchisundidzira bandwidth kupfuura miganhu yechinyakare mafotodetectors.

Single photon yekuona chirongwa
Iyo imwechete yekuona photon chirongwa chakakosha zvakanyanya kune quantum microwave photon masisitimu. Nheyo yekushanda ndeyotevera: 1. Iyo periodic trigger chiratidzo inowiriraniswa neyakayerwa chiratidzo inotumirwa kune TCSPC module. 2. Imwe chete photon detector inobudisa mutsara wemapulisi anomiririra mapikicha akaonekwa. 3. Iyo TCSPC module inoyera musiyano wenguva pakati peiyo trigger chiratidzo uye imwe neimwe yakaonekwa photon. 4. Mushure mezvishwe zvakati wandei, nguva yekuona histogram inotangwa. 5. Iyo histogram inogona kugadzirazve waveform yechiratidzo chepakutanga.Mathematics, inogona kuratidzwa kuti mukana wekuona photon panguva yakatarwa inofananidzwa nemagetsi ekuona panguva iyoyo. Naizvozvo, iyo histogram yenguva yekuona inogona kunyatso kumiririra waveform yechiratidzo chakayerwa.

Mabhenefiti akakosha e quantum microwave optical tekinoroji
Kana ichienzaniswa neyechinyakare microwave optical masisitimu, quantum microwave photonics ine akati wandei akakosha mabhenefiti: 1. Ultra-yakakwirira senitivity: Inoona zviratidzo zvisina kusimba zvakanyanya kusvika padanho rephoton rimwechete. 2. Bandwidth kuwedzera: kwete zvishoma ne bandwidth ye photodetector, inongobatwa chete nejitter yenguva yeimwe photon detector. 3. Yakasimbiswa kupesana-kupindira: TCSPC reconstruction inogona kusefa kunze kwezviratidzo zvisina kuvharwa kune chinokonzeresa. 4. Ruzha rwepazasi: Dzivisa ruzha rwunokonzerwa neyakajairwa mafotoelectric kuona uye kukwidziridzwa.
