The crazy world of quantum computing
Dirk Bouwmeester · Physics World · 2003
Quantum computers could be faster and more powerful than conventional computers. Moreover, they could trigger a revolutionary new approach to information processing. That is the intriguing message conveyed by the science journalist George Johnson in this short book. He explains how this new approach could undermine the security of current cryptography protocols, lead to fast algorithms for searching databases, and offer ways of simulating complex quantum-mechanical systems. However, the full scope of quantum computers is unknown. It might well be beyond our imagination.
