Itekhnoloji entsha yei-quantum photodetector
Eyona silicon incinci emhlabeni chip quantumifotodetector
Kutshanje, iqela lophando e-United Kingdom lenze impumelelo ebalulekileyo kwi-miniaturization yetekhnoloji ye-quantum, badibanisa ngempumelelo i-photodetector encinci ye-quantum yehlabathi kwi-silicon chip. Umsebenzi, onesihloko esithi "I-Bi-CMOS electronic photonic integrated circuit quantum light detector," ipapashwe kwi-Science Advances. Ngeminyaka yoo-1960, izazinzulu kunye neenjineli zaqala zatshintsha iitransistors ezincinci kwiimicrochips ezitshiphu, into entsha eyazisa ixesha lolwazi. Ngoku, izazinzulu zibonise okokuqala ukudityaniswa kwee-photodetectors ze-quantum zincinci kuneenwele zomntu kwi-silicon chip, zisisondeza inyathelo elinye kwixesha letekhnoloji ye-quantum esebenzisa ukukhanya. Ukufezekisa isizukulwana esilandelayo sobuchwephesha bolwazi oluphambili, ukuveliswa kwezixhobo eziphezulu ze-elektroniki kunye ne-photonic sisiseko. Ukuvelisa itekhnoloji ye-quantum kumaziko orhwebo akhoyo ngumngeni oqhubekayo wophando lweyunivesithi kunye neenkampani kwihlabathi liphela. Ukwazi ukwenza i-hardware ye-quantum esebenza kakhulu kumlinganiselo omkhulu kubalulekile kwi-computing ye-quantum, kuba nokwakha i-quantum computer kufuna inani elikhulu lamacandelo.
Abaphandi base-United Kingdom baye babonisa i-quantum photodetector kunye nommandla wesiphaluka odibeneyo we-80 microns ngama-microns angama-220 kuphela. Ubungakanani obuncinci obunjalo buvumela i-quantum photodetectors ukuba ikhawuleze kakhulu, eyimfuneko ekuvuleni ngesantya esiphezulu.unxibelelwano lwequantumkunye nokuvumela ukusebenza ngesantya esiphezulu seekhompyuter ze-optical quantum. Ukusetyenziswa kobuchule bokuvelisa obusekiweyo nobufumaneka ngokurhweba buququzelela ukusetyenziswa kwangethuba kwezinye iindawo zobuchwepheshe ezifana nokuvava nonxibelelwano. Ezo zichongi zisetyenziswa kwiintlobo ngeentlobo zezicelo kwi-quantum optics, zinokusebenza kwiqondo lobushushu begumbi, kwaye zifanelekile kunxibelelwano lwe-quantum, i-sensor ezibukhali kakhulu ezifana ne-state-of-the-art gravitational wave detectors, kunye noyilo lwe-quantum ethile. iikhompyutha.
Nangona ezi detectors zikhawuleza kwaye zincinci, zikwanobuthathaka kakhulu. Isitshixo sokulinganisa ukukhanya kwe-quantum luvakalelo kwingxolo ye-quantum. Ubuchwephesha be-Quantum buvelisa amanqanaba amancinci, asisiseko sengxolo kuzo zonke iinkqubo zamehlo. Ukuziphatha kwale ngxolo kutyhila ulwazi malunga nohlobo lokukhanya kwe-quantum oludluliselwe kwinkqubo, lunokugqiba uvakalelo lwe-sensor optical, kwaye lunokusetyenziselwa ukwakhiwa kwakhona kweemathematika kwi-quantum state. Uphononongo lubonise ukuba ukwenza i-optical detector ibe yincinci kwaye ikhawuleze ayizange ithintele ukuvakalelwa kwayo ekulinganiseni i-quantum states. Kwixesha elizayo, abaphandi baceba ukudibanisa enye i-hardware yetekhnoloji ye-quantum ephazamisayo kwisikali se-chip, ngakumbi ukuphucula ukusebenza kwentsha.umtshina wamehlo, kwaye uyivavanye kwiinkqubo ezahlukeneyo ezahlukeneyo. Ukwenza ukuba isixhobo sifumaneke ngokubanzi, iqela lophando liye layenza lisebenzisa imithombo ekhoyo yorhwebo. Nangona kunjalo, iqela ligxininisa ukuba kubalulekile ukuqhubeka nokujongana nemiceli mngeni yokuveliswa kwe-scalable ngeteknoloji ye-quantum. Ngaphandle kokubonisa ukuveliswa kwe-hardware ye-quantum ngokwenene, impembelelo kunye neenzuzo zobuchwepheshe be-quantum ziya kulibaziseka kwaye zilinganiselwe. Le mpumelelo ibonisa inyathelo elibalulekileyo ekuphumezeni izicelo ezinkuluiteknoloji yequantum, kunye nekamva le-quantum computing kunye ne-quantum communication igcwele amathuba angapheliyo.
