There are several mathematical formulations of quantum mechanics. The Schrödinger
picture expresses quantum states in terms of wavefunctions over, eg, position or momentum …

Quasiprobabilities are mathematical quantities describing the statistics of measurement
outcomes evaluated at two or more times, which incorporate the incompatibility of the …

In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Quantum theory is traditionally formulated using complex numbers. This imaginarity of
quantum theory has been quantified as a resource with applications in discrimination tasks …

Abstract The Kirkwood-Dirac quasiprobability distribution, intimately connected with the
quantum correlation function of two observables measured at distinct times, is becoming …

Kirkwood-Dirac representations of quantum states are increasingly finding use in many
areas within quantum theory. Usually, representations of this sort are only applied to provide …

Quantum imaginarity and quantum nonlocality capture the essence of quantumness of a
physical system from different aspects. We establish a connection between the imaginarity …

Quantum correlation functions are a natural way to encode multitime information, as they are
ubiquitous in analysis from fluctuation theorems to information scrambling. Correlation …

The Kirkwood–Dirac (KD) quasiprobability distribution can describe any quantum state with
respect to the eigenbases of two observables A and B. KD distributions behave similarly to …

In a multi-level quantum system Fano coherences stand for the formation of quantum
coherences due to the interaction with the continuum of modes characterizing an incoherent …
