Itekhnoloji yolwazi lweQuantum bubuchwephesha bolwazi obutsha obusekwe kubuxhakaxhaka be-quantum, obufaka iikhowudi, ukudibanisa kunye nokudlulisa ulwazi oluphathekayo oluqulethweinkqubo yequantum.Uphuhliso kunye nokusetyenziswa kobuchwephesha bolwazi lwe-quantum kuya kusizisa "kwixesha le-quantum", kwaye siqonde ukusebenza kakuhle okuphezulu, iindlela zonxibelelwano ezikhuselekileyo kunye nendlela yokuphila elula kunye neluhlaza.
Ukusebenza konxibelelwano phakathi kweenkqubo ze-quantum kuxhomekeke ekukwazi ukusebenzisana nokukhanya.Nangona kunjalo, kunzima kakhulu ukufumana izinto ezinokuthi zisebenzise ngokupheleleyo iipropathi ze-quantum ze-optical.
Kutshanje, iqela lophando kwi-Institute of Chemistry eParis kunye neKarlsruhe Institute of Technology ngokudibeneyo babonise amandla ekristale yemolekyuli esekwe kwi-ion europium ion yomhlaba (Eu³ +) kwizicelo kwiinkqubo ze-quantum ze-optical.Baye bafumanisa ukuba ukukhutshwa komgca womgca omxinwa kakhulu wale Eu³ + ikristale yemolekyuli yenza intsebenziswano esebenzayo nokukhanya kwaye inexabiso elibalulekileyounxibelelwano lwequantumkunye ne-quantum computing.
Umzobo 1: Unxibelelwano lwe-quantum olusekwe kumhlaba onqabileyo we-europium iikristale zemolekyuli
Amazwe e-Quantum anokubekwa phezulu, ngoko ke ulwazi lwe-quantum lunokubekwa ngaphezulu.I-qubit enye inokumela ngaxeshanye iindidi ezahlukeneyo zamazwe phakathi kwe-0 kunye ne-1, evumela ukuba idatha iqhutywe ngokuhambelana kwiibhetshi.Ngenxa yoko, amandla okubambisa iikhomputha ze-quantum aya kwanda ngokukhawuleza xa kuthelekiswa neekhompyuter zedijithali.Nangona kunjalo, ukuze kwenziwe imisebenzi yokubala, i-superposition of qubits kufuneka ikwazi ukuqhubeka ngokuqhubekayo ixesha elithile.Kwi-quantum mechanics, eli xesha lozinzo laziwa ngokuba bubomi bokuhambelana.Izijikelezo zenyukliya zeemolekyuli ezintsonkothileyo zinokufikelela kwizikhundla eziphezulu kunye nobomi obude obamileyo kuba impembelelo yemo engqongileyo kwijikeleziso zenyukliya ikhuselwe ngokufanelekileyo.
Iiyoni zomhlaba ezinqabileyo kunye neekristale zemolekyuli ziinkqubo ezimbini eziye zasetyenziswa kubuchwephesha bequantum.Ii-ion zomhlaba ezinqabileyo zineempawu ezibalaseleyo ze-optical kunye ne-spin, kodwa kunzima ukudityaniswa kuzoizixhobo zamehlo.Iikristale zemolekyuli kulula ukudibanisa, kodwa kunzima ukuseka unxibelelwano oluthembekileyo phakathi kwe-spin kunye nokukhanya kuba iibhanti zokukhupha zibanzi kakhulu.
Iikristale zemolekyuli zomhlaba ezinqabileyo eziphuhliswe kulo msebenzi zidibanisa ngobuchule izibonelelo zazo zombini kuba, phantsi kochulumanco lwelaser, i-Eu³ + inokukhupha iifotoni ezithwele ulwazi malunga nenyukliya spin.Ngovavanyo oluthile lwelaser, ujongano olusebenzayo lwe-optical/nuclear spin lunokwenziwa.Ngesi siseko, abaphandi baqonda ngakumbi inqanaba lenyukliya le-spin yokulungisa, ukugcinwa okuhambelanayo kweefotoni, kunye nokwenziwa komsebenzi wokuqala we-quantum.
Ukwenza i-quantum computing esebenzayo, ii-qubits eziphothiweyo ezininzi zidla ngokufuneka.Abaphandi babonise ukuba i-Eu³ + kwezi crystals zemolekyuli zingasentla zinokufikelela kwi-quantum entanglement ngodibaniso lombane olulahlekileyo, ngaloo ndlela luvumela ukusetyenzwa kolwazi lwe-quantum.Ngenxa yokuba iikristale zemolekyuli zineeyoni ezininzi zomhlaba ezinqabileyo, ukuxinana okuphezulu kwe-qubit kunokufezekiswa.
Enye imfuneko ye-quantum computing kukwazi ukujongana nee-qubits zomntu ngamnye.I-optical addressing technique kulo msebenzi inokuphucula isantya sokufunda kunye nokuthintela ukuphazamiseka komqondiso wesiphaluka.Xa kuthelekiswa nezifundo zangaphambili, ukuhambelana kwe-Optical ye-Eu³ + iikristale zemolekyuli ezichazwe kulo msebenzi ziphuculwe malunga newaka, ukuze amazwe ajikelezisa inyukliya aguqulwe ngendlela ethile.
Iimpawu ze-Optical zikwafanelekile ukusasazwa kolwazi lomgama omde ukudibanisa iikhomputha ze-quantum zonxibelelwano lwe-quantum ekude.Uqwalaselo olongezelelweyo lunokuqwalaselwa ekudityanisweni kweekristale ze-Eu³ + zemolekyuli entsha kwisakhiwo sefotoni ukunyusa umqondiso oqaqambileyo.Lo msebenzi usebenzisa iimolekyuli zomhlaba ezinqabileyo njengesiseko se-Intanethi ye-quantum, kwaye uthatha inyathelo elibalulekileyo kuyilo lwexesha elizayo lonxibelelwano lwe-quantum.
