Convex roofs witnessing Kirkwood-Dirac nonpositivity
Christopher Langrenez, Stephan De Bièvre, David R. M. Arvidsson-Shukur
Given two observables and , one can associate to every quantum state a Kirkwood-Dirac (KD) quasiprobability distribution. KD distributions are like joint classical probabili…
Almost no experiments have classical Kirkwood-Dirac representations
Christopher Langrenez, Wilfred Salmon, Stephan De Bièvre +3
A central problem in quantum information is determining quantum-classical boundaries. In the quasiprobability framework, a state is called classical if it is represented by a quasi…
Properties and Applications of the Kirkwood-Dirac Distribution
David R. M. Arvidsson-Shukur, William F. Braasch, Stephan De Bievre +6
Recent years have seen the Kirkwood-Dirac (KD) distribution come to the forefront as a powerful quasi-probability distribution for analysing quantum mechanics. The KD distribution…
