Toshiba wapanga ma algorithms a "quantum" kuti ayendetse pamakompyuta amakono

Posachedwapa bwanji Izo zinawulula, Toshiba safunikira kuyembekezera kubwera kwa makina a quantum computing kuti ayambe lero kuti athetse mavuto omwe sangaganizidwe kuti aphedwe pa makompyuta amakono. Kuti akwaniritse izi, Toshiba wapanga ma algorithms apulogalamu omwe alibe ma analogi.

Kufotokozera kwa algorithm kudasindikizidwa koyamba munkhani patsamba la Science Advances mu Epulo 2019. Kalelo, ngati malipoti angakhulupirire, akatswiri ambiri analonjera chilengezo cha Toshiba mokayikira. Ndipo tanthauzo la mawu awa ndikuti kuthana ndi zovuta zingapo, zomwe tikambirana pansipa, zida wamba zamakompyuta ndizoyenera - zida za seva, pa PC kapena mtolo wa makadi amakanema - omwe amathetsa mavuto mpaka 10 mwachangu. kuposa optical quantum kompyuta.

Chiyambireni kusindikizidwa kwa pepalali, Toshiba wachita zoyerekeza zingapo pogwiritsa ntchito "quantum" algorithm mu 2019. Monga momwe kampaniyo idanenera, poyimilira, potengera matrix a FPGA okhala ndi ma 2000 node (omwe adasewera gawo la zosinthika) komanso pafupifupi ma 2 miliyoni olumikizana ndi internode, yankho linawerengedwa mu 0,5 s. Kuthamanga kusaka yankho pa laser (optical) quantum simulator kunathetsa vutoli nthawi 10 pang'onopang'ono.

Kuyesera kuyerekezera arbitrage mu malonda a ndalama kunapereka yankho mu 30 milliseconds ndi mwayi wa 90% kupanga malonda opindulitsa. Kodi ndinganene kuti chitukukochi chinakopa chidwi kuchokera kumagulu azachuma?

Ndipo komabe, Toshiba sakufulumira kupereka ntchito zamalonda pogwiritsa ntchito ma algorithms a "quantum". Malinga ndi lipoti la Nikkei mu Disembala, Toshiba akufuna kupanga wocheperako kuti ayese ma aligorivimu otukuka pankhani yakusinthana pompopompo pakusinthana kwa ndalama. Panthawi imodzimodziyo, adzalandira ndalama zochepa ngati algorithm ili yabwino monga momwe amanenera.

Ponena za ma aligorivimu palokha, imayimira kutsanzira (kuyerekezera) kwa nthambi kapena zochitika za bifurcation kuphatikiza ma analogi otere mumakanika akale monga njira za adiabatic ndi ergodic. Apo ayi sizingakhale. Ma algorithm sangathe kukopa mwachindunji kumakina a quantum, chifukwa amagwira ntchito pama PC akale okhala ndi malingaliro a von Neumann.

Njira za Adiabatic mu thermodynamics amatanthauza njira zomwe sizingadutse kunja kapena kutsekedwa mwazokha, ndi ergodicity zikutanthauza kuti dongosolo lingathe kufotokozedwa poyang'ana chimodzi mwa zinthu zake. Nthawi zambiri, algorithm imayang'ana mayankho molingana ndi zomwe zimatchedwa kukhathamiritsa kophatikizana, pamene kuchokera pamitundu yambiri muyenera kupeza zophatikizira zingapo zoyenera. Sizingatheke kuthetsa mavuto otere mwa kuwerengera mwachindunji. Ntchito zotere zikuphatikiza mayendedwe, chemistry yama cell, malonda ndi zina zambiri zothandiza komanso zosangalatsa. Toshiba akulonjeza kuti ayamba kugwiritsa ntchito ma algorithms ake mu 2021. Sakufuna kudikirira zaka 10 kapena kuposerapo kuti makompyuta achulukidwe athetse mavuto a "quantum".
