- Abstract: We provide a coherence-based approach to nonclassical behavior by means of
distance measures. We develop a quantitative relation between coherence and
nonclassicality quantifiers, which establish the nonclassicality as the maximum
quantum-coherence achievable. We compute the coherence of several
representative examples and discuss whether the theory may be extended to
reference observables with continuous spectra.

theories: from "matter without matter" to the reappearance of time in quantum
gravity [75.38606213726906]
First-class phase-space constraints may be relaxed if we interpret them as fixing the values of new degrees of freedom.
This idea goes back to Fock and Stueckelberg, leading to restrictions of the gauge symmetry of a theory.
In particular, in the case of canonical quantum gravity, the Fock--Stueckelberg approach is relevant to the so-called problem of time.

Processes [0.0]
We focus on the relationship between Kolmogorov consistency of measurement statistics and the commutativity of measurement operators.
On the other hand, commutativity of measurement operators is a structural property that holds in classical physics.
We detail their implications for memoryless multi-time quantum processes.
