UToshiba uye waphuhlisa "quantum" algorithms ukuba isebenze kwiikhompyuter zanamhlanje

Njani mva nje Yatyhila, I-Toshiba ayifuni ukulinda ukufika kweenkqubo ze-computing ze-quantum ukuqala namhlanje ukuxazulula iingxaki ezingenakucingelwa ukuphunyezwa kwiikhomputha zanamhlanje. Ukufezekisa oku, uToshiba uphuhlise i-algorithms yesoftware engenazo ii-analogues.

Inkcazo ye-algorithm yaqala ukupapashwa kwinqaku kwi-website ye-Science Advances website Epreli 2019. Emva phayaa, ukuba iingxelo zinokuthenjwa, iingcali ezininzi zasamkela isibhengezo sikaToshiba ngokuthandabuza. Kwaye ingundoqo yale nkcazo kukuba ukusombulula inani leengxaki ezithile, esiza kuxoxa ngazo ngezantsi, i-hardware yekhompyutheni eqhelekileyo ifanelekile - i-hardware ye-server, i-PC okanye inqwaba yamakhadi evidiyo - eya kusombulula iingxaki ukuya kumaxesha angama-10 ngokukhawuleza. kunekhompyuter ye-optical quantum.

Ukusukela ekupapashweni kwephepha, uToshiba uye waqhuba inani lokulinganisa usebenzisa i-algorithm ye-"quantum" kuyo yonke i-2019. Njengoko inkampani ibike, kwi-stand, esekelwe kwi-matrix ye-FPGA ene-2000 nodes (eyayidlala indima yezinto eziguquguqukayo) kunye malunga ne-2 yezigidi ze-internode uxhumano, isisombululo sibalwa kwi-0,5 s. Ukuqhuba ukukhangela isisombululo kwi-laser (optical) ye-quantum simulator isombulule ingxaki amaxesha angama-10 ngokukhawuleza.

Iimvavanyo zokulinganisa i-arbitrage kwintengiso yemali yanika isisombululo kwi-milliseconds nje ye-30 kunye ne-90% yamathuba okwenza urhwebo olunenzuzo. Ngaba kufuneka nditsho ukuba uphuhliso lwatsala umdla ngokukhawuleza kwizangqa zemali?

Kwaye okwangoku, uToshiba akangxamanga ukubonelela ngeenkonzo zorhwebo usebenzisa i-algorithms "quantum". Ngokutsho kwengxelo kaNikkei ngoDisemba, uToshiba uceba ukudala i-subsidiary ukuvavanya i-algorithms ephuhlisiwe kwintsimi yokuthengiselana ngokukhawuleza ekutshintshisweni kwemali. Ngelo xesha, uya kufumana imali encinci ukuba i-algorithm ilungile njengoko bethetha ngayo.

Ngokuphathelele i-algorithm ngokwayo, imele imodeli (ukulinganisa) ye-branching okanye i-bifurcation phenomena ngokudibanisa ne-analogues kwi-classical mechanics njenge-adiabatic kunye neenkqubo ze-ergodic. Kungenjalo ayinakuba njalo. I-algorithm ayinakubhenela ngokuthe ngqo kwi-quantum mechanics, kuba isebenza kwiiPC zeklasi kunye ne-von Neumann logic.

Iinkqubo ze-Adiabatic kwi-thermodynamics bathetha iinkqubo ezingenakufikeleleka ngaphandle okanye zivaliwe ngokwazo, kwaye ergodicity kuthetha ukuba inkqubo inokuchazwa ngokujonga enye yezinto zayo. Ngokubanzi, i-algorithm ifuna izisombululo ngokwento ebizwa ngokuba ulungiselelo oludityanisiweyo, xa usuka kwizinto ezininzi eziguquguqukayo ufuna ukufumana iindibaniselwano ezininzi ezifanelekileyo. Akunakwenzeka ukucombulula iingxaki ezinjalo ngokubala ngokuthe ngqo. Imisebenzi enjalo ibandakanya izinto eziphathekayo, ikhemistri yeemolekyuli, ukurhweba kunye nezinye izinto ezininzi eziluncedo nezinomdla. UToshiba uthembisa ukuqalisa ukusetyenziswa okusebenzayo kwe-algorithms yakhe ngo-2021. Akafuni ukulinda iminyaka eyi-10 okanye ngaphezulu kwiikhompyuter ze-quantum ukusombulula iingxaki "ze-quantum".
