MAPLE procedures for the simulation of N-qubit quantum registers — •Thomas Radtke and Stephan Fritzsche — Universität Kassel, Institut für Physik, D–34109 Kassel, Germany

In the last decade, the field of quantum computation and quantum information has attracted an increasing amount of interest. By exploiting the long-known phenomenon of quantum entanglement, several interesting applications could be demonstrated successfully, such as efficient quantum computing or secure communication. However, apart from the promising perspectives of this new field of research, there are still a lot of open problems which remain to be solved, both in theory and experiment.

In order to facilitate the simulation of n-qubit quantum systems (quantum registers) we recently started to develop the Feynman program [1] which is a flexible and easily extendible hierarchy of procedures within the framework of the computer algebra system Maple. Currently, the Feynman program supports the definition and manipulation of n-qubit quantum registers as well as the application of unitary (and some user-defined non-unitary) quantum operations. Moreover, useful tools for the qualitative and quantitative analysis of the entanglement and separability properties in quantum registers are also provided.
