Maple tools for the simulation of quantum registers and their application to atomic processes — •Thomas Radtke1, Stephan Fritzsche2,3, and Andrey Surzhykov3,4 — 1Universität Kassel — 2Frankfurt Institute for Advanced Studies — 3GSI Helmholtzzentrum für Schwerionenforschung GmbH — 4Universität Heidelberg
Entanglement is known as a key resource in many quantum computation protocols. However, despite the successful experimental demonstration of several protocols, there are still many open questions concerning the role of entanglement in quantum algorithms or its protection against noisy environments.
To facilitate the simulation of quantum registers and the investigation of their entanglement properties, we have developed the Feynman package for Maple. It supports frequently used concepts like tensor products, partial traces, etc. Additionally, several popular states, quantum gates and noise models are predefined for convenient access. The program also implements a variety of separability criteria and (entanglement) measures to provide tools for the analysis of entanglement [1].
As application of the Feynman program, here we present two case
studies in the field of atomic physics [2]. First we investigate the spin
entanglement between photoion and photoelectron in the atomic photoionization.
The second study analyzes the polarization entanglement and nonlocality of
the photon pairs emitted during the decay of (metastable) hydrogen.
