Kanjani muva nje , I-Toshiba ayidingi ukulinda ukufika kwezinhlelo ze-computing ze-quantum ukuze ziqale namuhla ukuze kuxazululwe izinkinga ezingacabangeki ukubulawa kumakhompyutha anamuhla. Ukuze kuzuzwe lokhu, u-Toshiba uthuthukise ama-algorithms esofthiwe angenawo ama-analogue.
Incazelo ye-algorithm yashicilelwa okokuqala esihlokweni esikuwebhusayithi ye-Science Advances . Ngaleso sikhathi, uma imibiko izokholelwa, ochwepheshe abaningi basamukela ngokungabaza isimemezelo sikaToshiba. Futhi ingqikithi yalesi sitatimende ukuthi ukuxazulula inombolo yezinkinga ezithile, esizoxoxa ngazo ngezansi, i-hardware evamile yekhompiyutha ifanelekile - i-hardware ye-server, ye-PC noma inqwaba yamakhadi wevidiyo - azoxazulula izinkinga kuze kube izikhathi ezingu-10 ngokushesha. kunekhompyutha ye-optical quantum.
Selokhu kwashicilelwa leli phepha, u-Toshiba wenze izilinganiso eziningi zisebenzisa i-algorithm ye- "quantum" unyaka wonke ka-2019. Njengoba inkampani ibike, esitobhini, ngokusekelwe ku-matrix ye-FPGA enama-node angu-2000 (edlale indima yezinto eziguquguqukayo) kanye nokuxhumeka kwe-internode okulinganiselwa ezigidini ezingu-2, isixazululo sibalwa ngamasekhondi angu-0,5. Ukuqalisa ukusesha kwesixazululo kusifanisi se-laser (optical) quantum kuxazulule inkinga ngokuhamba kancane izikhathi ezingu-10.
Ukuhlolwa kokulingisa i-arbitrage ekuhwebeni kwezimali kunikeze isixazululo kuma-millisecond angama-30 nje ngamathuba angama-90% okwenza uhwebo olunenzuzo. Ngidinga ukusho ukuthi intuthuko yakhanga ngokushesha intshisekelo evela emibuthanweni yezezimali?
Futhi nokho, u-Toshiba akajahile ukuhlinzeka ngezinsizakalo zezohwebo esebenzisa ama-algorithms we-“quantum”. Ngokombiko we-Nikkei ngoDisemba, u-Toshiba uhlela ukwakha inkampani engaphansi ukuze ihlole ama-algorithms athuthukisiwe emkhakheni wokuthengiselana okusheshayo ekuhwebeni kwemali. Ngesikhathi esifanayo, uzothola imali encane uma i-algorithm ilungile njengoba besho ngakho.
Ngokuqondene ne-algorithm ngokwayo, imele ukumodela (ukulingiswa) kwezenzakalo ze-branching noma i-bifurcation ngokuhlanganiswe nama-analogue anjalo kumakhenikha akudala njengezinqubo ze-adiabatic kanye ne-ergodic. Kungenjalo ngeke kube. I-algorithm ayikwazi ukukhanga ngokuqondile kuma-quantum mechanics, ngoba isebenza kuma-PC wakudala ane-von Neumann logic.
ku-thermodynamics basho izinqubo ezingenakufinyeleleka ngaphandle noma ezivaliwe ngokwazo, futhi kusho ukuthi uhlelo lungachazwa ngokubheka enye yezakhi zalo. Ngokuvamile, i-algorithm isesha izixazululo ngokwalokho okubizwa , lapho kusuka kokuguquguqukayo okuningi udinga ukuthola izinhlanganisela ezimbalwa ezifanele. Akunakwenzeka ukuxazulula izinkinga ezinjalo ngokubala okuqondile. Imisebenzi enjalo ihlanganisa izinto ezisetshenziswayo, ikhemikhali yamangqamuzana, ukuhweba nezinye izinto eziningi eziwusizo nezithokozisayo. I-Toshiba ithembisa ukuqala ukusetshenziswa okusebenzayo kwama-algorithms ayo ngo-2021. Akafuni ukulinda iminyaka eyi-10 noma ngaphezulu ukuze amakhompyutha e-quantum axazulule izinkinga ze-"quantum".
