Quantum computers make use of the weird qualities of sub-atomic particles. So-called quantum particles can be in two places at the same time and also strangely connected even though they are millions of miles apart. Computer scientists have been trying to make an effective quantum computer for more than 20 years. Firms such as Google, IBM and Microsoft have developed simple machines. The new development paves the way for systems that can solve complex real world problems that the best computers we have today are incapable of. Quantum breakthrough could revolutionise computing but will this come to reality ?
