Phase-preserving linear amplifiers not simulable by the parametric amplifier
A. Chia, M. Hajdusek, R. Nair +3
It is commonly accepted that a parametric amplifier can simulate a phase-preserving linear amplifier regardless of how the latter is realized [Caves et al., Phys. Rev. A 86, 063802…

Phase diffusion and the small-noise approximation in linear amplifiers: Limitations and beyond
A. Chia, M. Hajdusek, R. Fazio +2
The phase of an optical field inside a linear amplifier is widely known to diffuse with a diffusion coefficient that is inversely proportional to the photon number. The same proces…
