Toshiba ya kirkiro algorithms "quantum" don aiki akan kwamfutoci na zamani

Yaya kwanan nan Ya bayyana, Toshiba baya buƙatar jira zuwan tsarin ƙididdiga na ƙididdiga don farawa a yau don magance matsalolin da ba za a yi tunanin kisa akan kwamfutocin zamani ba. Don cimma wannan, Toshiba ya ƙirƙiri algorithms na software waɗanda ba su da analogues.

An fara buga bayanin algorithm a cikin labarin akan gidan yanar gizon Ci gaban Kimiyya a ciki Afrilu 2019. A lokacin, idan za a yarda da rahotanni, masana da yawa sun gaishe da sanarwar Toshiba da shakku. Kuma jigon wannan bayanin shine don warware wasu takamaiman matsaloli, waɗanda za mu tattauna a ƙasa, kayan aikin kwamfuta na yau da kullun sun dace - hardware hardware, na PC ko dam na katunan bidiyo - wanda zai magance matsalolin har sau 10 cikin sauri. fiye da na'ura mai kwakwalwa ta kwamfuta.

Tun lokacin da aka buga takarda, Toshiba ta gudanar da siminti da yawa ta amfani da algorithm na "quantum" a cikin 2019. Kamar yadda kamfanin ya ruwaito, a tsaye, dangane da matrix na FPGA tare da nodes 2000 (wanda ya taka rawar masu canji) da kuma kusan haɗin haɗin gwiwar 2 miliyan 0,5, an ƙididdige maganin a cikin 10 s. Gudanar da neman mafita akan na'urar na'urar na'urar gani ta Laser (optical) quantum na'urar kwaikwayo ya warware matsalar sau XNUMX a hankali.

Gwaje-gwajen da aka yi kan yin sulhu a cikin kasuwancin kuɗi sun ba da mafita a cikin millisecond 30 kawai tare da yuwuwar kashi 90% na yin ciniki mai fa'ida. Ina bukata in ce ci gaban nan da nan ya jawo sha'awa daga da'irar kudi?

Kuma duk da haka, Toshiba ba shi da gaggawa don samar da sabis na kasuwanci ta amfani da algorithms "quantum". A cewar wani rahoto na Nikkei a watan Disamba, Toshiba yana shirin ƙirƙirar wani reshe don gwada algorithms masu tasowa a fagen hada-hadar kuɗi nan take akan musayar kuɗi. A lokaci guda, zai sami kuɗi kaɗan idan algorithm yana da kyau kamar yadda suke faɗi game da shi.

Amma ga algorithm kanta, yana wakiltar ƙirar ƙira (kwaikwaya) na reshe ko abubuwan al'amuran bifurcation a hade tare da irin waɗannan analogues a cikin injiniyoyi na gargajiya kamar hanyoyin adiabatic da ergodic. In ba haka ba ba zai iya zama ba. Algorithm ɗin ba zai iya yin kira kai tsaye ga injiniyoyin ƙididdiga ba, tunda yana aiki akan kwamfutoci na gargajiya tare da dabaru na von Neumann.

Ayyukan Adiabatic a cikin thermodynamics suna nuna matakan da ba za a iya wucewa zuwa waje ba ko rufe a kansu, kuma ergodicity yana nufin ana iya siffanta tsarin ta hanyar lura da ɗaya daga cikin abubuwansa. Gabaɗaya, algorithm yana neman mafita bisa ga abin da ake kira hadawa ingantawa, lokacin daga manyan masu canji da yawa kuna buƙatar nemo haɗe-haɗe masu kyau da yawa. Ba shi yiwuwa a magance irin waɗannan matsalolin ta hanyar lissafin kai tsaye. Irin waɗannan ayyuka sun haɗa da dabaru, sunadarai na ƙwayoyin cuta, ciniki da sauran abubuwa masu amfani da ban sha'awa. Toshiba yayi alƙawarin fara yaɗuwar amfani da algorithms ɗin sa a cikin 2021. Ba ta son jira shekaru 10 ko fiye don kwamfutoci masu yawa don magance matsalolin "kwamba".
