Efficient noiseless linear amplification for light fields with larger amplitudes

2016 · Optics Express

We suggest and investigate a scheme for non-deterministic noiseless linear amplification of coherent states using successive photon addition, (â(†))(2), where â(†) is the photon creation operator. We compare it with a previous proposal using the …

Optical estimation of unitary Gaussian processes without phase reference using Fock states

2020 · New Journal of Physics

Abstract Since a general Gaussian process is phase-sensitive, a stable phase reference is required to take advantage of this feature. When the reference is missing, either due to the volatile nature of the measured sample …

Classical emulation of quantum states with coherent mixtures

2021 · arXiv (Cornell University)

We propose a classical emulation methodology to emulate quantum phenomena arising from any non-classical quantum state using only a finite set of coherent states or their statistical mixtures. This allows us to successfully reproduce well-known …
