Imodeli yekhompyutha ye-Quantum ukusabela kwamakhemikhali
Inguqulo ye-chip ye-Sycamore quantum ye-Google, eyehlisiwe yafika ku-12 qubits, yalingisa ukusabela kwamakhemikhali, yabeka irekhodi lobunzima, kodwa akuyona into abacwaningi abathi ibaluleke kakhulu. Ongoti, abashicilele imiphumela yocwaningo lwabo ephephabhukwini iSayensi, bagcizelela ukuthi ukusetshenziswa kwalolu hlelo emkhakheni wamakhemikhali kukhombisa ukuguquguquka kwezinhlelo kanye nekhono lokuhlela umshini we-quantum ukwenza imisebenzi kunoma yimuphi umkhakha.
Ithimba laqale lamodela inguqulo eyenziwe lula yesimo samandla e-molecule, ehlanganisa ama-Sycamore qubits angu-12, amele i-electron eyodwa ye-athomu eyodwa. Okulandelayo, ukulingisa ukusabela kwamakhemikhali ku-molecule ne-nitrogen kwenziwa, okuhlanganisa izinguquko esakhiweni se-electronic sale molecule ezenzeka lapho ukuma kwama-athomu kushintsha.
Ngo-2017, i-IBM yenza ukulingisa kwamakhemikhali kusetshenziswa i-quantum six-qubit system. Ososayensi baqhathanisa lokhu nezinga lobunkimbinkimbi ososayensi abaseminyakeni engu-12 ababengalibala ngesandla. Ngokuphinda lelo nani libe ngama-qubits angu-80, i-Google ibala isistimu engabalwa kukhompuyutha engu-XNUMXs. Amandla ekhompyutha aphindwe kabili azosivumela ukuthi sifinyelele kwele-XNUMX, futhi ngokuzayo, amandla amanje wamakhompyutha. Ukuphakama kuphela kobuchwepheshe besimanje bekhompiyutha obuzobhekwa njengempumelelo hhayi kuphela ekufaniseni amakhemikhali.
