Makompyuta a Quantum amawonetsa machitidwe amankhwala

Mtundu wa Google's Sycamore quantum chip, wotsikira mpaka ku 12 qubits, udafanizira kachitidwe ka mankhwala, ndikuyika mbiri yazovuta, koma sichinthu chomwe ofufuza amati ndichofunika kwambiri. Akatswiriwa, omwe adasindikiza zotsatira za kafukufuku wawo m'magazini ya Science, akutsindika kuti kugwiritsa ntchito dongosolo la chemistry kumasonyeza kusinthasintha kwa dongosololi komanso luso lokonzekera makina a quantum kuti agwire ntchito iliyonse.

Gululo lidayamba kupanga mawonekedwe osavuta a mphamvu ya molekyulu, yokhala ndi ma qubit 12 a Sycamore, omwe amayimira electron imodzi ya atomu imodzi. Kenako, kuyezetsa zochita za mankhwala mu molekyu ndi nayitrogeni kunachitika, kuphatikizapo kusintha kwa magetsi a molekyu imeneyi kumene kumachitika pamene malo a atomu asintha.

Mu 2017, IBM idachita zoyeserera zamakina pogwiritsa ntchito quantum six-qubit system. Asayansi amayerekezera zimenezi ndi mlingo wa kucholoŵana kumene asayansi azaka za m’ma 12 angaŵerengere ndi manja. Pochulukitsa nambalayi mpaka 80 qubits, Google imawerengera makina omwe atha kuwerengedwa pamakompyuta XNUMXs. Kuwirikiza mphamvu zamakompyuta kudzatilola kuti tifike pa nambala XNUMX, ndipo mtsogolomo, luso lamakono la makompyuta. Kupambana kokha kwaukadaulo wamakono wamakompyuta kudzaganiziridwa kuti ndi njira yopambana osati pakupanga mankhwala.
