Tsis ntev los no , Toshiba tsis tas yuav tos txog qhov tshwm sim ntawm quantum suav tshuab pib hnub no los daws cov teeb meem uas tsis xav txog rau kev tua ntawm cov khoos phis tawj niaj hnub no. Txhawm rau ua tiav qhov no, Toshiba tau tsim software algorithms uas tsis muaj cov analogues.
Cov lus piav qhia ntawm algorithm tau luam tawm thawj zaug hauv ib tsab xov xwm ntawm Science Advances lub vev xaib hauv . Tom qab ntawd, yog tias cov ntawv ceeb toom yuav tsum ntseeg, ntau tus kws tshaj lij tau txais tos Toshiba cov lus tshaj tawm nrog kev tsis ntseeg. Thiab lub ntsiab lus ntawm cov lus no yog kom daws tau ntau yam teeb meem tshwj xeeb, uas peb yuav tham hauv qab no, lub khoos phis tawj zoo tib yam yog qhov tsim nyog - server hardware, rau PC lossis ib pob ntawm daim npav video - uas yuav daws teeb meem txog 10 npaug sai dua. dua li ib qho optical quantum computer.
Txij li thaum tshaj tawm cov ntawv, Toshiba tau ua ntau qhov kev sim siv "quantum" algorithm thoob plaws xyoo 2019. Raws li lub tuam txhab tau tshaj tawm, ntawm qhov sawv ntsug, raws li FPGA matrix nrog 2000 nodes (uas ua lub luag haujlwm ntawm kev hloov pauv) thiab kwv yees li 2 lab kev sib txuas hauv internode, kev daws teeb meem tau suav hauv 0,5 s. Khiav kev tshawb nrhiav kev daws teeb meem ntawm lub laser (optical) quantum simulator daws qhov teeb meem 10 zaus qeeb.
Kev sim ntawm simulating arbitrage nyob rau hauv txiaj trading muab ib tug daws nyob rau hauv tsuas yog 30 milliseconds nrog 90% qhov tshwm sim ntawm kev ua lag luam muaj txiaj ntsig. Xav tau kuv hais tias kev txhim kho tam sim ntawd tau txais kev txaus siab los ntawm cov voj voog nyiaj txiag?
Thiab tseem, Toshiba tsis nrawm los muab cov kev pabcuam lag luam siv "quantum" algorithms. Raws li Nikkei tsab ntawv ceeb toom nyob rau lub Kaum Ob Hlis, Toshiba npaj yuav tsim ib lub chaw ua hauj lwm los ntsuam xyuas cov tsim algorithms nyob rau hauv lub tshav pob ntawm instant muas ntawm cov txiaj pauv. Nyob rau tib lub sijhawm, nws yuav khwv tau nyiaj me ntsis yog tias lub algorithm zoo li lawv hais txog nws.
Raws li rau lub algorithm nws tus kheej, nws sawv cev rau ib tug qauv (simulation) ntawm branching los yog bifurcation phenomena nyob rau hauv ua ke nrog nrog xws analogues nyob rau hauv classical mechanics li adiabatic thiab ergodic txheej txheem. Txwv tsis pub nws ua tsis tau. Lub algorithm tsis tuaj yeem hais ncaj qha rau quantum mechanics, vim nws ua haujlwm ntawm classical PCs nrog von Neumann logic.
nyob rau hauv thermodynamics lawv imply cov txheej txheem uas impassable rau sab nraud los yog kaw nyob rau hauv lawv tus kheej, thiab txhais tau hais tias ib qho system tuaj yeem piav qhia los ntawm kev soj ntsuam ib qho ntawm nws cov ntsiab lus. Feem ntau, cov algorithm tshawb nrhiav cov kev daws teeb meem raws li qhov hu ua , thaum los ntawm ntau qhov sib txawv, koj yuav tsum nrhiav ntau qhov sib xyaw ua ke zoo. Nws tsis yooj yim sua kom daws tau cov teeb meem no los ntawm kev suav ncaj qha. Xws li cov dej num muaj xws li logistics, molecular chemistry, trading thiab ntau lwm yam tseem ceeb thiab nthuav. Toshiba cog lus tias yuav pib siv cov tswv yim dav dav ntawm nws cov algorithms hauv 2021. Nws tsis xav tos 10 xyoo lossis ntau dua rau quantum computers los daws cov teeb meem "quantum".
