Comments on the paper: Optical reflectance, optical refractive index and optical conductivity measurements of nonlinear optics for L-aspartic acid nickel chloride single crystal [PDF]
Optics Commun 361 (2016) 97-98, 2015 We argue that the L-aspartic acid nickel chloride crystal reported by the authors of the title paper (Optics Communications 2013) is actually the well-known diaqua(L-aspartato)nickel(II) hydrate crystal.

Strong converse for the classical capacity of optical quantum communication channels [PDF]
, 2015 We establish the classical capacity of optical quantum channels as a sharp transition between two regimes---one which is an error-free regime for communication rates below the capacity, and the other in which the probability of correctly decoding a ...
