Nts'etsopele ea theknoloji ea puisano ea quantum Chaena e hatetse pele ka mekhahlelo e 'maloa. Ho tloha mohatong oa thuto le lipatlisiso ka 1995, ka selemo sa 2000, Chaena e ne e se e phethile teko ea kabo ea senotlolo sa quantum e nkang 1.1 km. Nako ea ho tloha ka 2001 ho isa ho 2005 e ne e le mohato oa nts'etsopele e potlakileng eo ho eona liteko tse atlehileng tsa kabo ea senotlolo sa quantum libakeng tse 50 km le 125 km li ileng tsa phethahala [1].
Lilemong tsa morao tjena, Chaena e entse tsoelo-pele e kholo puisanong ea quantum. Chaena e bile ea pele ho qala sathelaete ea liteko tsa saense ea quantum, "Micius," 'me e hahile mohala oa puisano o sireletsehileng oa quantum o nkang lik'hilomithara tse likete pakeng tsa Beijing le Shanghai. Chaena e atlehile ho haha marang-rang a kopaneng a puisano ea quantum ho tloha lefatšeng ho ea sepakapakeng ka bolelele ba lik'hilomithara tse 4600. Ho phaella ho sena, Chaena e boetse e fihletse tsoelo-pele e ikhethang ho computing ea quantum. Mohlala, Chaena e ntlafalitse mohlala oa pele lefatšeng oa khomphutha ea quantum ea photonic, e atlehile ho haha mohlala oa khomphutha ea quantum "Jiuzhang" o nang le li-photon tse 76, 'me e atlehile ho haha mohlala oa khomphutha ea quantum o ka hlophisoang "Zu Chongzhi" o nang le li-qubit tse 62.
Tšebeliso ea karolo e sa sebetseng litsamaisong tsa puisano ea quantum ke ea bohlokoa haholo. Mohlala, lisebelisoa tse kang li-attenuator tsa microwave, li-couplers tsa directional, li-power divider, li-filter tsa microwave, li-phase shifters, le li-microwave isolators li ka sebelisoa. Lisebelisoa tsena li sebelisoa haholo-holo ho sebetsana le ho laola matšoao a microwave a hlahisoang ke li-bits tsa quantum.
Li-attenuator tsa microwave li ka fokotsa matla a matšoao a microwave ho thibela tšitiso likarolong tse ling tsa sistimi ka lebaka la matla a feteletseng a lets'oao. Li-couple tse tataisang li ka arola matšoao a microwave likarolo tse peli, ho nolofalletsa ts'ebetso e rarahaneng ea lets'oao. Li-filter tsa microwave li ka sefa matšoao a maqhubu a itseng bakeng sa tlhahlobo le ts'ebetso ea lets'oao. Li-phase shifter li ka fetola mohato oa matšoao a microwave, o sebelisetsoang ho laola boemo ba li-bits tsa quantum. Li-isolator tsa microwave li ka netefatsa hore matšoao a microwave a ata ka lehlakoreng le le leng feela, a thibela phallo ea lets'oao le tšitiso le sistimi.
Leha ho le jwalo, tsena ke karolo feela ya dikarolo tsa microwave tse sa sebetseng tse ka sebediswang puisanong ya quantum. Dikarolo tse ikgethang tse tla sebediswa di tla hloka ho kgethwa ho latela moralo le ditlhoko tsa sistimi e itseng ya puisano ya quantum.
Khopolo e fana ka mefuta e felletseng ea likarolo tsa microwave tse sa sebetseng bakeng sa puisano ea quantum
