I-quantum encinci ye-silicon chip emhlabeniisixhobo sokubona iifoto

Kutshanje, iqela lophando e-United Kingdom lenze inkqubela phambili ebalulekileyo ekuncitshisweni kwetekhnoloji ye-quantum, badibanise ngempumelelo i-quantum photodetector encinci kwihlabathi kwi-silicon chip. Lo msebenzi, onesihloko esithi "A Bi-CMOS electronic photonic integrated circuit quantum light detector," upapashwe kwiScience Advances. Kwiminyaka yoo-1960, izazinzulu kunye neenjineli baqala ukwenza ii-transistors ezincinci kwii-microchips ezingabizi, into entsha eyaqala kwixesha lolwazi. Ngoku, izazinzulu zibonakalise okokuqala ukuhlanganiswa kwee-quantum photodetectors ezincinci kuneenwele zomntu kwi-silicon chip, okusisondeza kwixesha letekhnoloji ye-quantum esebenzisa ukukhanya. Ukuze kufezekiswe isizukulwana esilandelayo setekhnoloji yolwazi ephucukileyo, ukuveliswa okukhulu kwezixhobo ze-elektroniki kunye ne-photonic ezisebenza kakhulu sisiseko. Ukuvelisa itekhnoloji ye-quantum kwiindawo zorhwebo ezikhoyo ngumceli mngeni oqhubekayo kuphando lweyunivesithi kunye neenkampani kwihlabathi liphela. Ukukwazi ukuvelisa izixhobo ze-quantum ezisebenza kakhulu kwinqanaba elikhulu kubalulekile kwi-quantum computing, kuba nokwakha ikhompyutha ye-quantum kufuna inani elikhulu lamacandelo.

Abaphandi e-United Kingdom babonise isixhobo sokubona i-quantum esinommandla wesekethe edibeneyo ye-80 microns kuphela nge-220 microns. Ubungakanani obuncinci kangaka buvumela izixhobo zokubona i-quantum ukuba zikhawuleze kakhulu, nto leyo ebalulekileyo ekuvuleni isantya esiphezulu.unxibelelwano lwe-quantumkunye nokuvumela ukusebenza ngokukhawuleza kweekhompyutha ze-optical quantum. Ukusebenzisa iindlela zokwenza ezisetyenzisiweyo nezifumanekayo kurhwebo kwenza kube lula ukusetyenziswa kwangoko kwezinye iindawo zobuchwepheshe ezifana nokuva kunye nonxibelelwano. Ezi zixhobo zokufumanisa zisetyenziswa kwiintlobo ngeentlobo zezicelo kwi-quantum optics, zinokusebenza kubushushu begumbi, kwaye zifanelekile kunxibelelwano lwe-quantum, izinzwa ezinobuthathaka kakhulu ezifana nezifumanisi zamaza anomtsalane zanamhlanje, kunye noyilo lweekhompyutha ezithile ze-quantum.

Nangona ezi detectors zikhawuleza kwaye zincinci, nazo zinobuthathaka kakhulu. Isitshixo sokulinganisa ukukhanya kwe-quantum kukuziva ingxolo ye-quantum. I-Quantum mechanics ivelisa amanqanaba amancinci, asisiseko engxolo kuzo zonke iinkqubo ze-optical. Indlela esebenza ngayo le ngxolo ityhila ulwazi malunga nohlobo lokukhanya kwe-quantum oludluliselwa kwinkqubo, lunokumisela uvakalelo lwe-optical sensor, kwaye lunokusetyenziswa ukwakha kwakhona ngokwezibalo imeko ye-quantum. Olu phononongo lubonise ukuba ukwenza i-optical detector ibe ncinci kwaye ikhawuleze akuzange kuyithintele uvakalelo lwayo ekulinganiseni iimeko ze-quantum. Kwixesha elizayo, abaphandi baceba ukudibanisa ezinye izixhobo zobuchwepheshe be-quantum eziphazamisayo kwisikali se-chip, ukuphucula ngakumbi ukusebenza kwentsha.isixhobo sokubona, kwaye uyivavanye kwiindlela ezahlukeneyo zokusetyenziswa. Ukuze i-detector ifumaneke ngokubanzi, iqela lophando liyilenzile lisebenzisa ii-founters ezithengiswayo. Nangona kunjalo, iqela ligxininisa ukuba kubalulekile ukuqhubeka nokujongana nemingeni yokwenziwa kwe-quantum hardware enokwandiswa ngetekhnoloji ye-quantum. Ngaphandle kokubonisa ukwenziwa kwe-quantum hardware enokwandiswa ngokwenene, impembelelo kunye neenzuzo zobuchwepheshe be-quantum ziya kulibaziseka kwaye zincitshiswe. Olu phumelelo lubonisa inyathelo elibalulekileyo ekufezekiseni usetyenziso olukhulu lwe-itekhnoloji ye-quantum, kwaye ikamva le-quantum computing kunye nonxibelelwano lwe-quantum lizele ngamathuba angenasiphelo.
