I-Quantum computing chips isheshisa kakhulu ukufunda ngomshini

I-D-Wave yaseCanada, okuyinkampani yokuqala emhlabeni yezentengiselwano ye-quantum computing, ithathe izinyathelo ezibalulekile zekusasa lekhompyutha enesivinini esikhulu, enabasebenzi abathobekile kuphela be-140.

Imibiko ye-PC World ukuthi i-D-Wave ithuthukise ikhompuyutha yayo yokuqala ye-quantum ngo-2011. Kusukela lapho, isithengiselwe inqwaba yezinhlangano ezifana ne-Lockheed Martin ne-NASA. Ngokusho kwe-Tech Republic, i-D-Wave iqongelele izigidi zamadola ekutshalweni kwezimali ezivela emaqenjini ahlukahlukene, afana noGoldman Sachs kanye ne-American CIA.

Ikhompyutha ye-D-Wave quantum ibiza ngaphezu kuka-$15 million, kubika i The Guardian. Iwebhusayithi ye-D-Wave ikhiqiza umkhiqizo wayo oyinhloko njenge "ikhompyutha ye-quantum ethuthuke kakhulu emhlabeni."

Ikhompiyutha isebenzisa izinto ezitholakele zesimanjemanje ze-theoretical physics futhi “ithinta ngokuqondile indwangu eyisisekelo yezinto ezingokoqobo.” Kubaluleke kakhulu kuhlobene nomqondo we-quantum superposition - ikhono lezinhlayiyana ukuba khona ezifundeni eziningi ezahlukene ngesikhathi esisodwa - kanye nekhono lezilinganiso ze-quantum ukukhombisa inhlanganisela eminingi yezilinganiso ze-physics yakudala ngesikhathi esisodwa.

Njengoba uNdunankulu u-Trudeau echaza, esikhundleni sokurekhoda ulwazi ngefomu kanambambili (a 1 noma 0), ikhompuyutha ye-quantum ingaqopha amathuba amaningi "ku-qubits" - okungaba ngu-1 noma u-0 or inhlanganisela yamanani amabili. Ukubalwa kwalawa manani kwenzeka ngesikhathi esisodwa futhi kukhiqiza amashumi ezinkulungwane zezimpendulo ngemizuzwana.

Ikhompuyutha ye-D-Wave quantum iqukethe ama-qubits angaphezu kwenkulungwane, futhi inani lamandla okugcina ulwazi likhula ngamandla.

Ikhompyutha ye-quantum ingaqedela izibalo kuphela endaweni elawulwa ngokuqinile - okungukuthi, kubanda kakhulu futhi kunengcindezi. Izingxenyekazi zekhompuyutha zisebenzisa i-niobium transistors apholiswa ukuze ibe uziro ngokuphelele (400x ukubanda kunomkhathi ongaphandle) ngokusebenzisa i-helium ewuketshezi. Ukushisa okukhulu kakhulu noma ukukhanya nje kungavimbela izibalo.

Ngokusho kwephini likamongameli omkhulu kwa-D-Wave, uJeremy Hilton, phakathi neminyaka emibili kuya kwemithathu i-D-Wave izobe isungule ikhompuyutha ye-quantum enkulu nakakhulu. Ngeshwa, lokhu akufani nokusebenza kwekhompuyutha okujwayelekile, futhi i-quantum computing kuzodingeka yenziwe yonke indawo ukuze ilungele ukusetshenziswa komuntu siqu.

I-D-Wave ibilokhu iphinda kabili inani lama-qubits kumakhompiyutha ayo e-quantum cishe kanye ngonyaka, kuphawula umqondisi we-D-Wave wezokuthuthukiswa kwebhizinisi nokusebenzisana kwamasu, u-Colin Williams.

UJohn Morton, uprofesa we-nanoelectronics kanye ne-nanophotonics e-UCL uthe amakhompiyutha okuqala e-quantum angeke atholakale okungenani iminyaka eyishumi. Liyoba njani ikusasa emkhayeni ovamile lapho amandla anjalo ekhompiyutha ezinkanyezi etholakala kalula?
