Uphuhliso lwetekhnoloji yonxibelelwano lwe-quantum e-China iqhubele phambili ngezigaba ezininzi.Ukuqala kwisigaba sophononongo kunye nophando ngo-1995, ngonyaka ka-2000, i-China yayigqibe umlinga wokusasaza ongundoqo we-quantum othatha i-1.1 km.Ithuba elisusela ku-2001 ukuya ku-2005 yayilinqanaba lophuhliso olukhawulezayo apho imifuniselo engundoqo yokusasazwa kwequantum kumgama wama-50 km kunye ne-125 km yaphunyezwa [1].
Kwiminyaka yakutshanje, i-China yenze impumelelo ebalulekileyo kunxibelelwano lwe-quantum.I-China yaba yeyokuqala ukuphehlelela i-quantum yesathelayithi yovavanyo lwesayensi, "Micius," kwaye yakhe umgca wonxibelelwano okhuselekileyo we-quantum ohamba amawaka eekhilomitha phakathi kweBeijing neShanghai.I-China iye yakha ngempumelelo uthungelwano lonxibelelwano lwe-quantum oludityanisiweyo ukusuka emhlabeni ukuya emajukujukwini kunye nesithuba esipheleleyo seekhilomitha ezingama-4600.Ukongeza koku, i-China ikwafumene inkqubela ephawulekayo kwi-quantum computing.Umzekelo, i-China iphuhlise iprototype yokuqala yehlabathi ye-photonic quantum computer, yakha ngempumelelo i-quantum computing prototype "Jiuzhang" ene-76 photons, kwaye iye yakha ngempumelelo i-programmable superconducting quantum computing prototype "Zu Chongzhi" equlethe i-62 qubits.
Ukusetyenziswa kwecandelo lokwenziwa kwezinto kwiinkqubo zonxibelelwano lomyinge kubaluleke kakhulu.Umzekelo, izixhobo ezinje nge-microwave attenuators, i-couplers eyalathiswayo, izahluli zamandla, izihluzi ze-microwave, izitshifti zesigaba, kunye nee-isolators ze-microwave zingasetyenziswa.Ezi zixhobo zisetyenziselwa ukusebenza kunye nokulawula imiqondiso ye-microwave eveliswa ngamasuntswana e-quantum.
Izithinteli zeMicrowave zinokunciphisa amandla emiqondiso ye-microwave ukuthintela ukuphazamiseka kwezinye iindawo zesistim ngenxa yamandla omqondiso ogqithisileyo.Ii-couplers ezithe gqolo zinokwahlula imiqondiso ye-microwave ibe ngamacandelo amabini, iququzelela ukusetyenzwa kwemiqondiso entsonkothileyo.Izihluzi zeMicrowave zinokuhluza imiqondiso yezakhelo ezithile zokuhlalutya umqondiso kunye nokusetyenzwa.Iziguquli zesigaba zingasitshintsha isigaba semiqondiso ye-microwave, esetyenziselwa ukulawula ubume be-quantum bits.I-isolators ye-Microwave inokuqinisekisa ukuba imiqondiso ye-microwave isasazeke kwicala elinye kuphela, inqanda ukubuya komqondiso kunye nokuphazamiseka kwinkqubo.
Nangona kunjalo, ezi yinxalenye kuphela yamacandelo e-microwave anokuthi asetyenziswe kunxibelelwano lomyinge.Amacandelo athile aza kusetyenziswa kuya kufuneka ukuba amiselwe ngokusekwe kuyilo kunye neemfuno zenkqubo ethile yonxibelelwano lomyinge.
Ingqikelelo ibonelela ngoluhlu olupheleleyo lwamacandelo e-microwave asebenzayo kunxibelelwano lomyinge
