Kuvandudzwa kwehunyanzvi hwekutaurirana tekinoroji muChina kwafambira mberi nematanho akati wandei.Kutanga kubva muchikamu chekudzidza uye chekutsvagisa muna 1995, pakazosvika gore ra2000, China yakanga yapedza quantum kiyi yekugovera kuyedza inotora 1.1 km.Iyo nguva kubva 2001 kusvika 2005 yaive chikamu chekukurumidza kusimudzira panguva iyo yakabudirira quantum yakakosha yekugovera miedzo pamusoro pemadaro e50 km uye 125 km yakaonekwa [1].
Mumakore achangopfuura, China yakaita budiriro huru mukutaurirana kwehuwandu.China ndiyo yaive yekutanga kuburitsa quantum sainzi yekuyedza setiraiti, "Micius," uye yakavaka tambo yakachengeteka yekutaurirana inotora zviuru zvemakiromita pakati peBeijing neShanghai.China yakabudirira kuvaka yakabatanidzwa quantum yekutaurirana network kubva pasi kuenda muchadenga ine hurefu hwakazara hwe4600 km.Pamusoro peizvi, China yakawanawo kufambira mberi kunoshamisa muquantum computing.Semuyenzaniso, China yakagadzira chimiro chekutanga chepasi rose chephotonic quantum komputa, yakabudirira kuvaka quantum computing prototype "Jiuzhang" ine 76 photon, uye yakabudirira kugadzira programmable superconducting quantum computing prototype "Zu Chongzhi" ine makumi matanhatu nemaviri qubits.
Kushandiswa kwechikamu chepasi muhuwandu hwekutaurirana masisitimu kwakakosha zvakanyanya.Semuyenzaniso, zvishandiso zvakaita sema microwave attenuators, anotungamira maviri ekubatanidza magetsi, microwave mafirita, phase shifters, uye microwave isolators zvinogona kushandiswa.Midziyo iyi inonyanya kushandiswa kugadzirisa nekudzora masaini emicrowave anogadzirwa ne quantum bits.
Microwave attenuators inogona kuderedza simba rema microwave masaini kudzivirira kukanganiswa nezvimwe zvikamu zvehurongwa nekuda kwesimba rakawandisa rechiratidzo.Madirectional couplers anogona kupatsanura microwave masaini muzvikamu zviviri, achifambisa zvakanyanya kuoma masaini kugadzirisa.Microwave mafirita anogona kusefa masaini echaiyo frequency yekuongorora uye kugadzirisa chiratidzo.Phase shifters inogona kushandura chikamu che microwave masiginecha, anoshandiswa kudzora mamiriro e quantum bits.Microwave isolators inogona kuve nechokwadi chekuti masaini emicrowave anopararira chete munzira imwe chete, kudzivirira chiratidzo chekudzokera shure uye kukanganisa system.
Nekudaro, izvi zvinongori chikamu chezvinongoita microwave zvikamu zvinogona kushandiswa muhuwandu hwekutaurirana.Iwo chaiwo ma componens achashandiswa angada kutariswa zvichibva pane dhizaini uye zvinodiwa zveiyo quantum communication system.
Concept inopa huwandu hwakazara hwe passive microwave zvikamu zvehuwandu hwekutaurirana
