Wehrl entropy, entropic uncertainty relations and entanglement
Stefan Floerchinger, Tobias Haas, Henrik Müller-Groeling
The Wehrl entropy is an entropy associated to the Husimi quasi-probability distribution. We discuss how it can be used to formulate entropic uncertainty relations and for a quantif…
Relative entropic uncertainty relation
Stefan Floerchinger, Tobias Haas, Ben Hoeber
Quantum uncertainty relations are formulated in terms of relative entropy between distributions of measurement outcomes and suitable reference distributions with maximum entropy. T…
Second law of thermodynamics for relativistic fluids formulated with relative entropy
Neil Dowling, Stefan Floerchinger, Tobias Haas
The second law of thermodynamics is discussed and reformulated from a quantum information theoretic perspective for open quantum systems using relative entropy. Specifically, the r…
Thermodynamics from relative entropy
Stefan Floerchinger, Tobias Haas
Thermodynamics is usually developed starting from entropy and the maximum entropy principle. We investigate here to what extent one can replace entropy with relative entropy which…
