Kukula kwa ukadaulo wolumikizirana ndi quantum ku China kwapita patsogolo m'magawo angapo. Kuyambira mu gawo lofufuza ndi kafukufuku mu 1995, pofika chaka cha 2000, China inali itamaliza kuyesa kugawa makiyi a quantum komwe kunatenga 1.1 km. Kuyambira 2001 mpaka 2005 inali gawo la chitukuko chachangu pomwe kuyesa kopambana kwa kugawa makiyi a quantum pa mtunda wa makilomita 50 ndi makilomita 125 kunakwaniritsidwa [1].
M'zaka zaposachedwapa, China yapanga chitukuko chachikulu pakulankhulana kwa quantum. China inali yoyamba kuyambitsa satelayiti yoyesera sayansi ya quantum, "Micius," ndipo yapanga chingwe cholumikizirana chotetezeka cha quantum chomwe chimadutsa makilomita masauzande ambiri pakati pa Beijing ndi Shanghai. China yapanga bwino netiweki yolumikizirana ya quantum kuchokera padziko lapansi kupita mumlengalenga yokhala ndi mtunda wa makilomita 4600. Kuphatikiza pa izi, China yapitanso patsogolo kwambiri pakuchita quantum computing. Mwachitsanzo, China yapanga chitsanzo choyamba padziko lonse cha kompyuta ya photonic quantum, yapanga bwino chitsanzo cha quantum computing "Jiuzhang" chokhala ndi ma photon 76, ndipo yapanga bwino chitsanzo cha superconducting quantum computing "Zu Chongzhi" chokhala ndi ma qubits 62.
Kugwiritsa ntchito gawo lopanda mphamvu mu machitidwe olumikizirana a quantum ndikofunikira kwambiri. Mwachitsanzo, zipangizo monga ma microwave attenuators, ma directional couplers, ma power dividers, ma microwave filters, ma phase shifters, ndi ma microwave isolators zingagwiritsidwe ntchito. Zipangizozi zimagwiritsidwa ntchito makamaka pokonza ndikuwongolera ma microwave signals opangidwa ndi ma quantum bits.
Zoletsa ma microwave zimatha kuchepetsa mphamvu ya ma signal a microwave kuti zisasokonezeke ndi mbali zina za dongosolo chifukwa cha mphamvu yochulukirapo ya ma signal. Zolumikizira zolunjika zimatha kugawa ma signal a microwave m'magawo awiri, zomwe zimathandiza kukonza ma signal ovuta kwambiri. Zosefera za microwave zimatha kusefa ma signal a ma frequency enaake kuti ziwunikenso ndi kukonza ma signal. Zosintha ma phase zimatha kusintha gawo la ma signal a microwave, omwe amagwiritsidwa ntchito kuwongolera momwe ma quantum bits alili. Zosiyanitsa ma microwave zimatha kuonetsetsa kuti ma signal a microwave amafalikira mbali imodzi yokha, kuletsa kubwerera kwa ma signal ndi kusokoneza dongosolo.
Komabe, izi ndi gawo chabe la zigawo za microwave zomwe zimagwiritsidwa ntchito polankhulana kwa quantum. Zinthu zomwe zigwiritsidwe ntchito ziyenera kutsimikiziridwa kutengera kapangidwe ndi zofunikira za makina olankhulana a quantum.
Lingaliro limapereka mitundu yonse ya zida zolumikizirana za microwave zomwe sizigwira ntchito
