PV V: Plenary Talk

Wednesday, March 26, 2003, 09:00–09:45, Audimax

Quantum information and quantum optical systems — •I. Cirac — Max-Planck Institut für Quantenoptik, Garching

Quantum information processing and communication is a multidisciplinary field of research in which the goal is to use some of the intriguing properties of quantum mechanics in order to process and transmit information. For the moment, there are very few systems on which one can test the main ideas of quantum computing, perhaps the most important application in this field. On the one hand, we have quantum optical systems, typically atoms or ions, which interact with laser fields and that are trapped by electromagnetic forces. On the other, we have solid state devices (quantum dots or superconductor devices, for example) which can be electronically controlled. In this talk I will revise some of the ideas of how to perform quantum computations using atoms, ions and photons, and present some other applications of quantum information theory.
