Improving parameters estimation in Gaussian channels using quantum coherence

JFG Santos, CHS Vieira, WR Cardoso - arXiv preprint arXiv:2409.09675, 2024 - arxiv.org
Gaussian quantum channels are relevant operations in continuous variable systems. In
general, given an arbitrary state, the action on it is well-known provided that the quantum …
