I-Canada ihola indlela yekusasa le-quantum

Inkampani yaseCanada i-D-Wave iyisinyathelo esisodwa sokusondela ekufakazeleni ukufaneleka kwekhompyutha yabo ye-quantum D-Wave Two. Imiphumela yokuhlolwa okubonisa izimpawu zomsebenzi we-quantum kukhompuyutha isanda kushicilelwa ku-Physical Review X, iphephabhuku elibuyekezwe ngontanga.

Kodwa yini ikhompyutha ye-quantum?

Ikhompyutha ye-quantum ithobela imithetho ye-quantum physics, okungukuthi, i-physics ezingeni elincane kakhulu. Izinhlayiya ezincane ziziphatha ngendlela ehluke kakhulu kunezinto zansuku zonke esizibonayo. Lokhu kubanika izinzuzo ngaphezu kwamakhompyutha avamile, athobela imithetho ye-classical physics.

Isibonelo, ikhompuyutha ephathekayo yakho icubungula imininingwane njengamabhithi: oziro abalandelanayo noma ababodwa. Amakhompiyutha e-Quantum asebenzisa ama-qubits okuthi, ngenxa yomcimbi we-quantum obizwa ngokuthi "i-superposition," angaba amaziro, awo, noma kokubili ngesikhathi esisodwa. Njengoba ikhompuyutha ingacubungula zonke izinketho ngasikhathi sinye, ishesha kakhulu kunalokho obekungake kwenzeke kukho.

Izinzuzo zaleli jubane zibonakala lapho kuxazululwa izinkinga zezibalo eziyinkimbinkimbi lapho kunedatha eningi kakhulu engahlungwa ngamasistimu avamile.

Abagxeki beQuantum

Inkampani yaseBrithani Columbia ithengise amakhompyutha ayo ku-Lockheed Martin, i-Google, ne-NASA kusukela ngo-2011. Lokhu kunakekelwa kwegama elikhulu akuzange kumise abagxeki ekugxekeni izimangalo zenkampani. UScott Aaronson, uprofesa eMassachusetts Institute of Technology, ungomunye walabo abakhuluma kakhulu.

Kubhulogi yakhe, u-Aaronson uthi izimangalo zika-D-Wave "azisekelwa ubufakazi obukhona njengamanje." Nakuba ekwamukela ukuthi ikhompuyutha isebenzisa izinqubo ze-quantum, uveza ukuthi amanye amakhompyutha ajwayelekile enze kahle kakhulu i-D-Wave Two. Uyavuma ukuthi u-D-Wave usethuthukile, kodwa uthi "izimangalo zabo ... zinolaka kakhulu kunalokho."

I-Quantum Legacy yaseCanada

Amakhompiyutha e-D-Wave akuwona kuphela intuthuko ye-quantum physics ukugqoka ibheji laseCanada.

Ngo-2013, ama-encoded qubits aphikelela ekushiseni kwekamelo cishe izikhathi eziyi-100 kunanini ngaphambili. Iqembu lamazwe ngamazwe elizuze umphumela beliholwa uMike Thewalt waseSimon Fraser University eBritish Columbia.

E-Waterloo, e-Ont., URaymond Laflamme, umqondisi omkhulu we-The Institute for Quantum Computing (IQC), uthengise ngomtshina we-photon osebenzisa ubuchwepheshe be-quantum. Inhloso yakhe elandelayo kulesi sikhungo ukwakha ikhompuyutha ye-quantum esebenzayo. Kodwa umshini onjalo wawungenzani ngempela?
