Nts'etsopele ea theknoloji ea puisano ea quantum China e hatetse pele ka mekhahlelo e mengata. Ho qala ho tloha mohatong oa boithuto le lipatlisiso ka 1995, ka selemo sa 2000, China e ne e qetile tlhahlobo ea mantlha ea kabo ea quantum e nkang 1.1 km. Nako ea ho tloha ka 2001 ho ea ho 2005 e ne e le mohato oa tsoelo-pele e potlakileng nakong eo liteko tse atlehileng tsa kabo ea quantum libakeng tsa 50 km le 125 km li ile tsa phethahala [1].
Lilemong tsa morao tjena, China e entse tsoelo-pele e kholo puisanong ea quantum. China e bile eona ea pele ea ho hlahisa sathelaete ea liteko tsa mahlale a quantum, "Micius," mme e thehile mohala o sireletsehileng oa puisano o nkang lik'hilomithara tse likete lipakeng tsa Beijing le Shanghai. China e atlehile ho aha marangrang a likhokahano a quantum ho tloha lefats'eng ho ea sebakeng se nang le bolelele ba lik'hilomithara tse 4600. Ho phaella ho sena, Chaena e boetse e fihletse tsoelo-pele e tsotehang ea quantum computing. Mohlala, China e thehile mofuta oa pele oa lefats'e oa khomphutha ea photonic quantum, 'me e atlehile ho aha "Jiuzhang" ea quantum computing e nang le lifoto tse 76,' me e atlehile ho aha "Zu Chongzhi" e nang le li-qubits tse 62.
Tšebeliso ea karolo e sa sebetseng lits'ebetsong tsa puisano tsa quantum e bohlokoa haholo. Mohlala, lisebelisoa tse joalo ka li-attenuators tsa microwave, li-coupler tse tataisang, li- divider tsa motlakase , li-filters tsa microwave, li- phase shifter, le li- isolators tsa microwave li ka sebelisoa. Lisebelisoa tsena li sebelisoa haholo ho sebetsana le ho laola matshwao a microwave a hlahisoang ke li-quantum bits.
Li-attenuators tsa microwave li ka fokotsa matla a mats'oao a microwave ho thibela tšitiso le likarolo tse ling tsa sistimi ka lebaka la matla a mats'oao a feteletseng. Li-couplers tsa Directional li ka arola matšoao a microwave likarolo tse peli, e leng ho nolofatsang ts'ebetso e rarahaneng ea matshwao. Li-filters tsa microwave li ka sefa matšoao a maqhubu a khethehileng bakeng sa tlhahlobo le ts'ebetso ea matšoao. Phase shifters e ka fetola mohato oa mats'oao a microwave, a sebelisetsoang ho laola boemo ba quantum bits. Li-isolators tsa microwave li ka etsa bonnete ba hore mats'oao a microwave a hasana ka nqa e le 'ngoe, a thibela ho khutla le ho kena-kenana le sistimi.
Leha ho le joalo, tsena ke karolo feela ea likaroloana tsa microwave tse ka sebelisoang puisanong ea quantum. Likarolo tse ikhethileng tse tla sebelisoa li tla hloka ho khethoa ho ipapisitsoe le moralo le litlhoko tsa sistimi e itseng ea puisano ea quantum.
Concept e fana ka mefuta e mengata ea likarolo tsa microwave tse sa sebetseng bakeng sa puisano ea quantum
