This lecture gives an introduction to quantum computing, sensing, and communication, with a focus on basic mathematical and physical concepts unerpinning these emerging quantum technologies.
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 …
This lecture gives an introduction to topics related to quantum computing and quantum information theory.
In this master seminar we discuss elements of modern information theory and how they reflect in quantum mechanics as well as quantum field theory.
