Ikoreshwa rya kwant microwave ya tekinoroji

Gukoresha kwanttekinoroji ya microwave

Kugaragaza ibimenyetso bidakomeye
Bumwe mu buryo butanga ikizere cya tekinoroji ya kwant microwave ya fotonike ni ukumenya ibimenyetso bya microwave / RF cyane. Ukoresheje foton imwe imwe, sisitemu irumva cyane kuruta uburyo gakondo. Kurugero, abashakashatsi berekanye sisitemu ya microwave ya fotonike ya sisitemu ishobora kumenya ibimenyetso biri munsi ya -112.8 dBm nta amplificatifike ikoreshwa. Iyi ultra-high sensitivite ituma biba byiza mubisabwa nkitumanaho ryimbitse.

Microwave Photonicsgutunganya ibimenyetso
Quantum microwave Photonics nayo ishyira mubikorwa ibikorwa byogukoresha umurongo mwinshi wo gutunganya ibimenyetso nko guhinduranya icyiciro no kuyungurura. Bakoresheje ibikoresho bya optique bikwirakwiza no guhindura uburebure bwumucyo, abashakashatsi berekanye ko icyiciro cya RF gihinduka kugeza kuri 8 GHz RF yo kuyungurura umurongo kugeza kuri 8 GHz. Icyangombwa, ibyo biranga byose bigerwaho hifashishijwe ibikoresho bya elegitoroniki 3 GHz, byerekana ko imikorere irenze imipaka yagutse

Ibihe bidasanzwe byaho kugirango ushushanye igihe
Ubushobozi bumwe bushimishije buzanwa na kwant kwangirika ni ugushushanya inshuro zitari iz'igihe. Ubu buhanga bushobora gushushanya umurongo wikurikiranya-wapompa imwe-fotone isoko kumwanya mugihe kiri kure. Sisitemu ikoresha foton ikomatanyirijwe hamwe aho urumuri rumwe runyura muyungurura rwerekana ikindi rukanyura mu kintu gitatanye. Bitewe ninshuro ziterwa na fotone ifatanye, uburyo bwo kuyungurura uburyo bwashushanijwe butari hafi yigihe cyagenwe.
Igishushanyo 1 kirerekana iki gitekerezo:

Ubu buryo bushobora kugera kubipimo byoroshye bitarinze gukoresha neza urumuri rwapimwe.

Kwiyunvikana
Quantummicrowave optiqueikoranabuhanga ritanga kandi uburyo bushya bwo kwikuramo ibyuma byerekana umurongo mugari. Bakoresheje ibintu bidasanzwe biboneka muri kwantum, abashakashatsi berekanye kwant compression compression sensing ishobora gukira10 GHz RFKugaragaza. Sisitemu ihindura ibimenyetso bya RF kuri polarisiyasi ya coherent Photon. Kumenyekanisha-fotone imwe noneho itanga matrike isanzwe yo gupima kugirango yunvikane. Muri ubu buryo, ikimenyetso cyagutse gishobora kugarurwa ku gipimo cya Yarnyquist.

Ikwirakwizwa rya Quantum
Usibye kuzamura porogaramu gakondo ya microwave ya fotonike, tekinoroji ya kwant irashobora kandi kunoza sisitemu yitumanaho rya kwant nko gukwirakwiza kwant (QKD). Abashakashatsi berekanye subcarrier multiplex quantum urufunguzo rwo gukwirakwiza (SCM-QKD) muguhuza microwave Photons subcarrier kuri sisitemu yo gukwirakwiza kwant (QKD). Ibi bituma urufunguzo rwinshi rwigenga rwoherezwa hejuru yumurongo umwe wumucyo, bityo bikongerera imbaraga imikorere.
Igishushanyo cya 2 cyerekana igitekerezo nibisubizo byubushakashatsi bwa sisitemu ebyiri-zitwara SCM-QKD:

Nubwo kwant microwave Photonics tekinoroji itanga ikizere, haracyari imbogamizi:
1. Ubushobozi buke burigihe-bushoboka: Sisitemu iriho isaba igihe kinini cyo kwegeranya kugirango twongere twubake ibimenyetso.
2. Ingorane zo guhangana n'ibimenyetso biturika / Imiterere imwe: Imiterere y'ibarurishamibare yo kwiyubaka igabanya imikoreshereze y’ibimenyetso bidasubirwaho.
3. Hindura kuri microwave yukuri: Imiterere yinyongera irasabwa kugirango uhindure amateka ya histogramu yubatswe mumashanyarazi akoreshwa.
4.
5. Kwishyira hamwe: Sisitemu nyinshi muri iki gihe zikoresha ibice byinshi byihariye.

Kugira ngo ibyo bibazo bikemuke kandi biteze imbere urwego, hagaragara ibyerekezo byubushakashatsi bitanga icyizere:
1. Gutegura uburyo bushya bwo gutunganya ibimenyetso-nyabyo no gutahura kimwe.
2. Shakisha porogaramu nshya zikoresha sensibilité nyinshi, nko gupima microse.
3. Kurikirana ishyirwa mubikorwa rya fotone hamwe na electron kugirango ugabanye ubunini nuburemere.
4.
5. Huza tekinoroji ya microwave Photon tekinoroji hamwe nubundi buhanga bugaragara.
