Ikoreshwa rya quantumIkoranabuhanga rya microwave fotoniki

Kumenya ibimenyetso bidakomeye
Imwe mu mikoreshereze ishimishije cyane ya ikoranabuhanga rya quantum microwave photonics ni ukumenya ibimenyetso bya microwave/RF bidakomeye cyane. Mu gukoresha uburyo bwo gutahura fotoni imwe, ubu buryo burushaho kuba bwiza kurusha uburyo busanzwe. Urugero, abashakashatsi bagaragaje uburyo bwa quantum microwave photonic bushobora kumenya ibimenyetso biri hasi nka -112.8 dBm nta ikoranabuhanga rihagije ryo kongera imbaraga. Ubu buryo bwo kumva ibintu buri hejuru cyane butuma buba bwiza cyane mu bikorwa nko mu itumanaho ryimbitse.

Ifotoniki za mikoroondegutunganya ibimenyetso
Ikoranabuhanga rya microwave rya Quantum rinakoresha imikorere yo gutunganya ibimenyetso bya bandwidth nini nko guhindura no kuyungurura. Mu gukoresha ikintu gitanga urumuri gikwirakwira no guhindura uburebure bw'urumuri, abashakashatsi bagaragaje ko RF phase yimukira kuri 8 GHz RF filtering bandwidths kugeza kuri 8 GHz. Icy'ingenzi ni uko ibi byose bigerwaho hakoreshejwe ikoranabuhanga rya 3 GHz, bigaragaza ko imikorere irenze imipaka isanzwe ya bandwidth.

Ingano zitari zo mu gace runaka zo gupima igihe
Ubushobozi bumwe bushimishije bwatewe no gufungana kwa quantum ni ugushushanya umurongo utari uwo mu gace runaka n'igihe. Ubu buryo bushobora guhuza spectrum y'isoko rya fotoni imwe itangwa n'umuraba ukomeza ku murongo w'igihe uri ahantu kure. Sisitemu ikoresha fotoni ebyiri zifatanye aho urumuri rumwe runyura muri filter ya spectral n'urundi runyura muri filime itatanye. Bitewe n'uko fotoni zifatanye, uburyo bwo kuyungurura spectral bushyirwa ku murongo utari uwo mu gace runaka w'igihe.
Ishusho ya 1 igaragaza iki gitekerezo:

Ubu buryo bushobora kugera ku gupima neza spectral hatabayeho guhindura mu buryo butaziguye isoko y'urumuri rwapimwe.

Gutahura ibintu mu buryo bufunze
Quantummikoroonde y'amashanyaraziIkoranabuhanga rinatanga uburyo bushya bwo kumva ibimenyetso bya interineti bikonjeshejwe. Bakoresheje uburyo bwo gushakisha quantum, abashakashatsi bagaragaje uburyo bwo kumva quantum bukonjeshejwe bushobora kugarura10 GHz RFspectra. Sisitemu ihindura ikimenyetso cya RF ku miterere ya polarization ya fotoni ihuje. Gutahura fotoni imwe bitanga matrix karemano yo gupima ibintu mu buryo butunguranye kugira ngo umuntu amenye neza. Muri ubu buryo, ikimenyetso cya interineti gishobora kugarurwa ku gipimo cya Yarnyquist.

Gukwirakwiza urufunguzo rwa Quantum
Uretse kunoza uburyo busanzwe bwo gukoresha ikoranabuhanga rya quantum, ikoranabuhanga rya quantum rishobora no kunoza uburyo bwo gutumanaho bwa quantum nka quantum key distribution (QKD). Abashakashatsi bagaragaje ko icyuma gikwirakwiza icyuma gitwara amashanyarazi (SCM-QKD) gikoresha icyuma gitwara amashanyarazi (micro-photons subcarrier) kuri sisitemu ya quantum key distribution (QKD). Ibi bituma icyuma cyigenga cya quantum cy’urumuri gikwirakwira mu buryo butandukanye, bityo bikongera imikorere myiza ya spectral.
Ishusho ya 2 igaragaza igitekerezo n'ibyavuye mu igerageza rya sisitemu ya SCM-QKD ifite ibikoresho bibiri:

Nubwo ikoranabuhanga rya quantum microwave photonics ritanga icyizere, haracyari imbogamizi zimwe na zimwe:
1. Ubushobozi buke bwo gukoresha mu gihe nyacyo: Sisitemu iriho ubu isaba igihe kinini cyo gukusanya kugira ngo yongere ikore ikimenyetso.
2. Ingorane zo guhangana n'ibimenyetso bitunguranye/bimwe: Imiterere y'ibarurishamibare y'ivugurura igabanya ubushobozi bwabyo ku bimenyetso bidasubiramo.
3. Hindura uhindure imiterere nyayo ya mikoroonde: Intambwe zindi zirakenewe kugira ngo histogram yongeye gukoreshwa ihindurwemo imiterere y'imiraba ikoreshwa.
4. Ibiranga igikoresho: Hakenewe inyigo y'inyongera ku myitwarire y'ibikoresho bya quantum na microwave photonic mu buryo buhuriweho.
5. Guhuza: Sisitemu nyinshi muri iki gihe zikoresha ibice binini bitandukanye.

Kugira ngo ibyo bibazo bikemuke kandi bitere imbere, hari icyerekezo cy’ubushakashatsi gitanga icyizere kirimo kugaragara:
1. Gutegura uburyo bushya bwo gutunganya ibimenyetso mu buryo bwihuse no kubitahura rimwe.
2. Suzuma porogaramu nshya zikoresha ubushobozi bwo gupima ibintu mu buryo bworoshye, nko gupima mikorosife y'amazi.
3. Gukurikirana ishyirwa mu bikorwa rya fotoni na electron zivanze kugira ngo ugabanye ingano n'ubuhanga.
4. Wige uburyo urumuri rukorana neza mu miyoboro ya fotonike ya quantum.
5. Huza ikoranabuhanga rya fotoni ya microwave ya quantum n'andi mashya agezweho ya quantum.
