Distinguishability measures between ensembles of quantum states
Ognyan Oreshkov, John Calsamiglia
A quantum ensemble is a set of quantum states each occurring randomly with a given probability. Quantum ensembles are necessary to describe situations with incompl…

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…
