Kev txhim kho ntawm quantum kev sib txuas lus thev naus laus zis hauv Suav teb tau dhau los ntawm ntau theem. Pib los ntawm txoj kev tshawb fawb thiab kev tshawb fawb theem hauv xyoo 1995, los ntawm xyoo 2000, Tuam Tshoj tau ua tiav qhov kev sim quantum tseem ceeb faib ua 1.1 km. Lub sij hawm ntawm 2001 txog 2005 yog ib theem ntawm kev loj hlob sai thaum lub sij hawm ua tiav quantum tseem ceeb faib thwmsim nyob deb ntawm 50 km thiab 125 km twb paub lawm [1].
Nyob rau hauv xyoo tas los no, Tuam Tshoj tau ua qhov tseem ceeb hauv kev sib txuas lus quantum. Tuam Tshoj yog thawj tus tsim lub quantum science sim satellite, "Micius," thiab tau tsim lub quantum ruaj ntseg kev sib txuas lus hla ntau txhiab kilometers ntawm Beijing thiab Shanghai. Tuam Tshoj tau ua tiav ib qho kev sib txuas lus quantum kev sib txuas lus los ntawm lub ntiaj teb mus rau qhov chaw nrog tag nrho qhov ntev ntawm 4600 mais. Ntxiv rau qhov no, Tuam Tshoj kuj tau ua tiav qhov kev vam meej hauv quantum xam. Piv txwv li, Tuam Tshoj tau tsim lub ntiaj teb thawj tus qauv ntawm photonic quantum computer, ua tiav lub quantum xam prototype "Jiuzhang" nrog 76 photons, thiab tau ua tiav lub programmable superconducting quantum xam prototype "Zu Chongzhi" muaj 62 qubits.
Kev siv cov khoom siv passive hauv quantum kev sib txuas lus yog qhov tseem ceeb tshaj plaws. Piv txwv li, cov khoom siv xws li microwave attenuators, directional couplers, power dividers, microwave filters, phase shifters, and microwave isolators may be used. Cov khoom siv no feem ntau yog siv los ua cov txheej txheem thiab tswj cov teeb liab microwave tsim los ntawm quantum khoom.
Microwave attenuators tuaj yeem txo lub zog ntawm cov teeb liab microwave los tiv thaiv kev cuam tshuam nrog lwm qhov ntawm lub cev vim muaj teeb meem ntau dhau. Directional couplers tuaj yeem faib cov teeb liab microwave rau hauv ob feem, ua kom yooj yim dua cov teeb liab ua. Microwave filters tuaj yeem lim tawm cov cim ntawm cov zaus tshwj xeeb rau kev tsom xam thiab kev ua haujlwm. Phase shifters tuaj yeem hloov cov theem ntawm microwave teeb liab, siv los tswj lub xeev ntawm quantum khoom. Microwave isolators tuaj yeem ua kom ntseeg tau tias cov teeb liab microwave tsuas yog nthuav tawm hauv ib qho kev coj, tiv thaiv cov teeb liab rov qab thiab cuam tshuam nrog lub cev.
Txawm li cas los xij, cov no tsuas yog ib feem ntawm cov khoom siv microwave passive uas yuav siv tau hauv kev sib txuas lus quantum. Cov khoom siv tshwj xeeb uas yuav tsum tau siv yuav tsum tau txiav txim siab raws li tus qauv tsim thiab cov kev xav tau ntawm kev sib txuas lus tshwj xeeb quantum.
