Tomogram-based homodyne nonclassical area and sum tomographic entropy provide experimentally accessible quantifiers that track the onset, fractional revivals, and decay of nonclassicality in damped nonlinear optical media.
Absence of coherent superpositions in the coherent-state basis is a sufficient condition for Wigner function positivity, necessary and sufficient for cat states and limiting cases of higher-order cat states.
Boson correlations for states with well-behaved Glauber-Sudarshan P-representations are spurious statistical correlations due to Simpson's paradox from symmetry-breaking in ensemble averages over varying geometries.
Negative quantum states from discrete Wigner functions show resilience advantages over Bell states under non-Markovian dynamics, are protected via weak measurements, and are realized on IBM superconducting hardware.
The paper provides an expository review of squeezed states of light and related phenomena using the Wigner phase-space formalism and groups such as Lorentz and symplectic.
