Robust multi-hypothesis quantum-state discrimination under unknown common unitary perturbations via least favorable priors
Daichi Fujiki, Fuyuhiko Tanaka
We study robust K-ary quantum-state discrimination when all candidate states are affected by the same unknown common unitary perturbation. The unknown perturbation does not represe…
Adaptive quantum state estimation for two optical point sources
Masataka Kimizu, Fuyuhiko Tanaka, Akio Fujiwara
In classical optics, there is a well-known resolution limit, called Rayleigh's curse, in the separation of two incoherent optical sources in close proximity. Recently, Tsang et al.…
Reliable Characterization for Improving and Validating Accurate Quantum Operations
Takanori Sugiyama, Shinpei Imori, Fuyuhiko Tanaka
A reliable method for characterizing quantum operations that is suitable for improving and validating their accuracies is indispensable for realizing a practical quantum computer.…
Quantum Minimax Theorem
Fuyuhiko Tanaka
Recently, many fundamental and important results in statistical decision theory have been extended to the quantum system. Quantum Hunt-Stein theorem and quantum locally asymptotic…
New derivation of Born's law and parameter estimation based on a relative state formulation
Fuyuhiko Tanaka
Excluding the concept of probability in quantum mechanics, we derive Born's law from the remaining postulates in quantum mechanics using type method. We also give a way of determin…
Generalized Bayesian predictive density operators
Fuyuhiko Tanaka
Recently the quantum Bayesian prediction problem was formulated by Tanaka and Komaki (2005). It is shown that Bayesian predictive density operators are the best predictive density…
