Bayesian approach to simultaneous quantum multiparameter estimation with finite data
Chun Kit Dennis Law, József Zsolt Bernád
Multiparameter estimation remains a fundamental challenge in quantum estimation theory because the optimal measurements associated with different parameters are generally incompati…
Entanglement in bipartite X-states: Analytical results for the volume of states with positive partial transpose
Yaqing Xy Wang, József Zsolt Bernád
We provide an analytical formula for the volume ratio between bipartite X-states with positive partial transpose and all bipartite X-states. The result applies to arbitrary $m \tim…
Bayesian and frequentist estimators for the transition frequency of a driven two-level quantum system
Chun Kit Dennis Law, József Zsolt Bernád
The formalism of quantum estimation theory with a specific focus on classical data postprocessing is applied to a two-level system driven by an external gyrating magnetic field. We…
Iterates of quantum operations
J. Z. Bernád
Iterates of quantum operations and their convergence are investigated in the context of mean ergodic theory. We discuss in detail the convergence of the iterates and show that the…
