Kukula kwaukadaulo waukadaulo wolumikizana ndi quantum ku China kwadutsa magawo angapo. Kuyambira mu gawo la kafukufuku ndi kafukufuku mu 1995, pofika chaka cha 2000, dziko la China linali litamaliza kuyesa kogawa kofunikira komwe kumatenga 1.1 km. Nthawi yochokera ku 2001 mpaka 2005 inali gawo lachitukuko chofulumira pomwe zoyeserera zazikuluzikulu zogawa zamtundu wa 50 km ndi 125 km zidakwaniritsidwa [1].
M'zaka zaposachedwa, China yachita bwino kwambiri pakulumikizana kwa quantum. China inali yoyamba kukhazikitsa satellite yoyeserera ya sayansi ya quantum, "Micius," ndipo yapanga njira yolumikizirana yotetezeka yodutsa masauzande a makilomita pakati pa Beijing ndi Shanghai. China yapanga bwino njira yolumikizirana yolumikizirana kuchokera padziko lapansi kupita kumlengalenga ndi kutalika kwa makilomita 4600. Kuphatikiza pa izi, China yapezanso kupita patsogolo kodabwitsa pamakompyuta a quantum. Mwachitsanzo, dziko la China lapanga makina oyamba padziko lonse lapansi amtundu wa photonic quantum, kupanga bwino makina a quantum computing "Jiuzhang" okhala ndi mafotoni 76, ndipo apanga bwino "Zu Chongzhi" yemwe ali ndi ma qubits 62.
Kugwiritsiridwa ntchito kwa chigawo chochepa mu machitidwe oyankhulana ndi quantum ndikofunikira kwambiri. Mwachitsanzo, zida monga zolumikizira ma microwave, zolumikizira zowongolera, zogawa mphamvu, zosefera ma microwave, zosinthira magawo, ndi zopatula ma microwave zitha kugwiritsidwa ntchito. Zidazi zimagwiritsidwa ntchito pokonza ndikuwongolera ma siginecha a microwave opangidwa ndi ma quantum bits.
Ma microwave attenuators amatha kuchepetsa mphamvu ya ma siginecha a microwave kuti apewe kusokoneza mbali zina zamakina chifukwa champhamvu yamagetsi yochulukirapo. Ma Directional couplers amatha kugawa ma siginecha a microwave m'magawo awiri, ndikupangitsa kuti ma siginecha avutike kwambiri. Zosefera za Microwave zimatha kusefa ma siginecha a ma frequency apadera kuti athe kusanthula ndi kukonza ma siginecha. Osintha magawo amatha kusintha gawo la ma siginecha a microwave, omwe amagwiritsidwa ntchito kuwongolera kuchuluka kwa ma quantum bits. Odzipatula pa microwave amatha kuwonetsetsa kuti ma siginecha a microwave amafalikira mbali imodzi, kuletsa kubweza kwa ma sign ndi kusokoneza dongosolo.
Komabe, awa ndi gawo chabe la magawo a ma microwave omwe angagwiritsidwe ntchito pakulankhulana kwachulukidwe. Zida zomwe zigwiritsidwe ntchito ziyenera kutsimikiziridwa malinga ndi mapangidwe ndi zofunikira za njira yolumikizirana ya quantum.
Lingaliro limapereka magawo athunthu azinthu zapa microwave zolumikizirana mochuluka
