Ukuba ungumthandi wekhompyuter ye-quantum, ngokuqinisekileyo isihloko sale post besingaphezulu kokumangalisa, ukuba ngokuchaseneyo awukabikho mva nje ngokwenzekayo kweli lizwe, ngokuqinisekileyo isihloko, kuncinci okushiyekileyo uyanele ice cream, ungazi ncam nokuba ubhiyozela into okanye hayi. Ukuphuma nakuphi na ukungathandabuzeki, ndikuxelele Sijongene nantoni na engaphantsi kwesiganeko esingazange sabonwa ngaphambili.
Ngokukodwa, sijamelene nerekhodi elitsha ngokwekhompyuter ye-quantum, efanayo ngokuchasene noko unokucinga, ngeli xesha, khange ivunwe ziinkampani ezinobungakanani kunye notyalo-mali kule ndawo njenge-IBM, uGoogle okanye u-Microsoft, kodwa iyahambelana neqela leenzululwazi ezivela kwi URainer Blatt elebhu yolingo ye-physics yeYunivesithi yaseInnsbruck (Ostriya).
Uninzi lwamaziko afuna ukwenza eyona khomputha ye-quantum nangona, ngoku, le rekhodi ibanjwe yiYunivesithi yaseInnsbruck
Kude kulo mdyarho wokuba ngabanini beyona khompyuter inamandla kwaye inakho ukubanakho kwiplanethi, into ebonakala kamsinya kunokuba iGoogle izakufezekisa kunye neprosesa yayo entsha ye-72-qubit, iwela ngokuchanekileyo kwiYunivesithi yaseInnsbruck, ngaphandle kokuba, njengoko bekunjalo, uGoogle angalinganisa qubit nganye yenkqubo yayo kwaye abeke igama leziko lakho ecaleni kwerekhodi entsha.
Ukuzama ukuqonda ngcono ukuba kutheni i-quantum computing ifanelekile ngalo mzuzu, sinokuthi, njengoko kunokufundwa kwenye indawo, ukuba i-qubit ifana nqwa nesiko kwaye konke ukufana kuphelela apha, ukusukela kwinto yesiNtu, njenge Siyayazi, inamazwe amabini ahlukeneyo ahlala emelwe njenge-0 kunye ne-1. Sithetha ngababini bee-atom ezixakekileyo ezinokuba nazo zombini ezi zinto ngaxeshanye.
Enkosi ngokuchanekileyo kwinto yokuba i-qubit inokuba namazwe aphezulu, amandla ethiyori anokufikelelwa yiprosesa ye-quantum iphindaphindwe. Ngokusisiseko kwaye ephepheni, ikhompyuter ye-quantum inokwenza imisebenzi entsonkothileyo ngemizuzwana, ngokufana nekhompyuter yendabuko inokuthatha amashumi eminyaka. Ngelishwa, ngenxa yolu lungelelwaniso lwamazwe, kufuneka sazi imeko ethile ngaphandle kwempazamo yokwenza irejista ezinzileyo, kungenjalo, siya kuba neprosesa ezele zii-atom ezingenakunikela nto.
Ukulungiselela ukuzinza ukuya kwii-qubits ezingama-20, ion ion calcium isetyenzisiwe phantsi kwemagnethi yomhlaba.
Enye yezona zinto zibalulekileyo zenziwe yiprojekthi liqela labaphandi kwiYunivesithi yase-Innsbruck kukwazi ukuba, ukuze kuzinziswe ii-qubits zeqonga layo basebenzise ion calcium egcinwe ngumgibe we-ion apho kusetyenziswa imagnethi yomhlaba. Kule nto kufuneka songeze ukuba, ukuze kudityaniswe ii-qubits, kusetyenziswa iinkqubo ezahlukeneyo ze-laser.
Kolu vavanyo, indlela entsha yokufumanisa yenzelwe imeko ye-qubit nganye nganye. Le ndlela intsha ifuna ukuphuhliswa kwendlela entsha efuna ukubalwa okukhulu kodwa, njengenzuzo, kufanele ukuba iqatshelwe ukuba isebenza ngakumbi kwaye ichanekile. Ukufumana umbono wokusebenza kwayo, qaphela ukuba abo banoxanduva lwale projekthi bafezekisile Qinisekisa ukwakheka kwamathathu kunye namaqela ukuya kuthi ga kwiine nangaphezulu ezintlanu.
Njengoko abo banoxanduva lweprojekthi begqabazisile, inyathelo elilandelayo kukudibanisa ukuya kuthi ga kwi-50 qubits ngomlinganiso ozimeleyo ngamnye kubo. Njengeenkcukacha, xelela ukuba, ukuba bayayiphumeza le njongo, Siza kujongana nokutsiba okuyimfuneko kuyo nayiphi na ikhompyuter ye-quantum ukuba namandla ngakumbi namhlanje kunayo nayiphi na i-supercomputers.
