Parameter estimation in the presence of the most general Gaussian dissipative reservoir
Marcin Jarzyna, Marcin Zwierz
We analyze the performance of quantum parameter estimation in the presence of the most general Gaussian dissipative reservoir. We derive lower bounds on the precision of phase esti…
Compatibility in Multiparameter Quantum Metrology
Sammy Ragy, Marcin Jarzyna, Rafal Demkowicz-Dobrzanski
Simultaneous estimation of multiple parameters in quantum metrological models is complicated by factors relating to the (i) existence of a single probe state allowing for optimal s…
Super-additivity in communication of classical information through quantum channels from a quantum parameter estimation perspective
Jan Czajkowski, Marcin Jarzyna, Rafal Demkowicz-Dobrzanski
We point out a contrasting role the entanglement plays in communication and estimation scenarios. In the first case it brings noticeable benefits at the measurement stage (output s…
