Sci­en­tists make quan­tum leap in com­put­ing

China Daily (Canada) - - NEWS CAPSULE -

Chinese sci­en­tists have built the world’s first quan­tum com­put­ing ma­chine that goes far be­yond the early clas­si­cal or con­ven­tional com­put­ers, paving the way to the ul­ti­mate re­al­iza­tion of quan­tum com­put­ing.

The sci­en­tists an­nounced their achieve­ment at a press con­fer­ence in the Shang­hai In­sti­tute for Ad­vanced Stud­ies of Univer­sity of Sci­ence and Tech­nol­ogy of China.

Sci­en­tists be­lieve quan­tum com­put­ing could in some ways dwarf the pro­cess­ing power of to­day’s su­per­com­put­ers. This could ef­fec­tively solve largescale com­pu­ta­tion prob­lems that are be­yond the abil­ity of cur­rent clas­si­cal com­put­ers, said Pan Jian­wei, an aca­demi­cian of the Chinese Academy of Sci­ences and a lead­ing quan­tum physi­cist.

One anal­ogy to ex­plain the con­cept of quan­tum com­put­ing is that it is like be­ing able to read all the books in a li­brary at the same time, whereas con­ven­tional com­put­ing is like hav­ing to read them one af­ter an­other.
