Phase estimation for thermal Gaussian states
M. Aspachs, J. Calsamiglia, R. Munoz-Tapia +1
We give the optimal bounds on the phase-estimation precision for mixed Gaussian states in the single-copy and many-copy regimes. Specifically, we focus on displaced thermal and squ…
Phase-Covariant Quantum Benchmarks
J. Calsamiglia, M. Aspachs, R. Munoz-Tapia +1
We give a quantum benchmark for teleportation and quantum storage experiments suited for pure and mixed test states. The benchmark is based on the average fidelity over a family of…
Phase variance of squeezed vacuum states
Emilio Bagan, Alex Monras, Ramon Munoz-Tapia
We consider the problem of estimating the phase of squeezed vacuum states within a Bayesian framework. We derive bounds on the average Holevo variance for an arbitrary number o…
