Generalized Limits for Single-Parameter Quantum Estimation
Sergio Boixo, Steven T. Flammia, Carlton M. Caves +1
We develop generalized bounds for quantum single-parameter estimation problems for which the coupling to the parameter is described by intrinsic multi-system interactions. For a Ha…
Generalized Coherent States as Preferred States of Open Quantum Systems
Sergio Boixo, Lorenza Viola, Gerardo Ortiz
We investigate the connection between quasi-classical (pointer) states and generalized coherent states (GCSs) within an algebraic approach to Markovian quantum systems (including b…
On Decoherence in Quantum Clock Synchronization
Sergio Boixo, Carlton M. Caves, Animesh Datta +1
We study two quantum versions of the Eddington clock-synchronization protocol in the presence of decoherence. The first protocol uses maximally entangled states to achieve the Heis…
