Toshiba yakagadzira "quantum" algorithms yekushandisa pamakomputa emazuva ano.

Zvakadini munguva pfupi yapfuura ZvakaratidzaToshiba haifanire kumirira kuti masisitimu e quantum computing atange kugadzirisa matambudziko asingafungidzike pamakombiyuta emazuva ano. Kuti izvi zviitike, Toshiba yakagadzira ma algorithms esoftware asina anoenzana nawo.

Nzira iyi yekutanga yakatsanangurwa munyaya iri pawebhusaiti yeScience Advances. Kubvumbi 2019Panguva iyoyo, maererano nemishumo, nyanzvi dzakawanda dzakagamuchira chiziviso chaToshiba nekusava nechokwadi. Chinhu chikuru chechiziviso ichi chaive chekuti, pamabasa akati wandei akakurukurwa pazasi, hardware yemakomputa yakajairika—server hardware, PC hardware, kana musanganiswa wemakadhi evhidhiyo—yaizokodzera uye inokwanisa kugadzirisa matambudziko nekukurumidza kanosvika kagumi kupfuura optical quantum computer.

Mushure mekuburitswa kwechinyorwa ichi, Toshiba yakaita masimulation akatevedzana achishandisa quantum algorithm mugore ra2019. Sekureva kwekambani, pa rig yakavakirwa paFPGA array ine ma node zviuru zviviri (akashanda sevariables) uye angangoita mamiriyoni maviri ekubatanidza ma node, mhinduro yacho yakaverengerwa mumasekonzi 0,5. Kutsvaga mhinduro pa laser (optical) quantum simulator kwakagadzirisa dambudziko iri zvishoma nezvishoma kagumi.

Kuedza kwakaitwa pakuenzanisa arbitrage mukutengeserana kwemari kwakaburitsa mhinduro mumamirisekonzi makumi matatu chete, paine mukana we90% wekuita kutengeserana kunobatsira. Hazvina basa kutaura kuti budiriro iyi yakabva yakwezva kufarira kwemakambani emari.

Zvisinei, Toshiba haisati yatanga kupa mabasa ekutengeserana ichishandisa ma "quantum" algorithms. Sekureva kwemushumo waZvita Nikkei, Toshiba inoronga kugadzira kambani yekuedza ma "algorithms" akagadzirwa mumunda wekutengeserana nekukurumidza pamari. Ichaitawo purofiti diki, kana algorithm yacho yakanaka sezvavanotaura.

Kana iri algorithm pachayo, imuenzaniso (simulation) wezviitiko zve branching kana bifurcation zvakabatana nezvimwe zvakafanana mu classical mechanics se adiabatic uye ergodic processes. Hazvigoneke kuva zvakasiyana. Algorithm haigone kukwezva zvakananga quantum mechanics, sezvo ichishanda pamakombiyuta ekare ane von Neumann logic.

Maitiro eAdiabatic mu thermodynamics zvinoreva maitiro asingagone kupfuudzwa kunze kana kuti akavharwa mukati mawo, uye ergodicity zvinoreva kuti sisitimu inogona kutsanangurwa nekutarisa chimwe chezvinhu zvayo. Kazhinji, algorithm inotsvaga mhinduro zvichienderana nezvinonzi kugadzirisa zvinhu pamwe chete, apo musanganiswa wakawanda wakakodzera unofanirwa kuwanikwa kubva mumhando dzakasiyana-siyana dzezvinhu. Matambudziko akadaro haagone kugadziriswa nekuverenga zvakananga. Matambudziko akadaro anosanganisira logistics, molecular chemistry, kutengeserana, nedzimwe nzvimbo dzakawanda dzinobatsira uye dzinonakidza. Toshiba inovimbisa kutanga kushandiswa kwakapararira kwemaalgorithms ayo muna 2021. Kambani haidi kumirira makore gumi kana kupfuura kuti makombiyuta equantum agadzirise matambudziko e "quantum".
