Kanada tana jagorantar hanyar zuwa ƙididdige gaba
Kamfanin D-Wave na Kanada mataki ɗaya ne kusa da tabbatar da ingancin kwamfutarsu ta D-Wave Biyu. Sakamakon gwajin da ke nuna alamun aiki na ƙididdigewa a cikin kwamfutar kwanan nan an buga su a cikin Nazarin Jiki X, wata jarida da aka yi bita da juna.
Amma menene kwamfuta ta ƙididdiga?

Misali, kwamfutar tafi-da-gidanka tana sarrafa bayanai azaman rago: sifili a jere ko na ɗaya. Kwamfutocin Quantum suna amfani da qubits wanda, godiya ga taron ƙididdiga da ake kira "superposition," na iya zama sifili, ɗaya, ko duka biyu a lokaci guda.
