Optimal quantum estimation of the Unruh-Hawking effect
Mariona Aspachs, Gerardo Adesso, Ivette Fuentes
We address on general quantum-statistical grounds the problem of optimal detection of the Unruh-Hawking effect. We show that the effect signatures are magnified up to potentially o…
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…
