Approximately two decades ago, it was shown theoretically that quantum computers could easily solve certain computationally demanding problems like factoring large numbers into prime numbers or searching efficiently in databases. These possibilities have triggered intense experimental efforts towards the physical realization of scalable quantum processors (such that it would be possible to increase the size of their quantum register).
