Let $\N$ be a bosonic Gaussian channel, and let the optimal squashing channel in Equation … is always a bosonic Gaussian channel. This conjecture would reduce the optimization defi…

Let $V_{AB}$ be a covariance matrix (QCM) of a bipartite Gaussian state. Let $E^{\mathrm{\scriptscriptstyle \, G}}_\downarrow(V_{AB})$ denote Gaussian intrinsic entanglement and le…

Equality conjecture. The measures $E_{sq,c}$ and $E_{sq}$ may be the same.

Separation conjecture. The same situation of incomparable measures should occur between $E_I$ and $E_r$ (and $E_r^\infty$), between $E_{sq}$ and $E_{r,\leftrightarrow}^\infty$ (and…
