Entropic entanglement criteria in phase space

We derive inseparability criteria for the phase space representation of quantum states in terms of variants of Wehrl's entropy. In contrast to entropic criteria involving differential entropies of marginal phase space distributions, our criteria are …

Quantum computing and quantum information

This lecture gives an introduction to topics related to quantum computing and quantum information theory.

Information theory and quantum physics

In this master seminar we discuss elements of modern information theory and how they reflect in quantum mechanics as well as quantum field theory.
