Quantum information processing
To increase computing power, computer chips get crammed with ever-growing numbers of transistors. But miniaturization makes chips vulnerable to undesirable quantum-mechanical effects that prevent them from behaving in the intended 'classical' way. Celebrated proposals of Feynman and Deutsch from the 1980s suggested that, instead of fighting these effects, we should use them to our advantage and design computers based on their principles, giving birth to the currently thriving field of quantum computing. In this talk I will introduce the basic ideas behind quantum information processing and discuss some of its most striking applications and phenomena.
