Optimal estimation of a physical observable's expectation value for pure states
A. Hayashi, M. Horibe, T. Hashimoto
We study the optimal way to estimate the quantum expectation value of a physical observable when a finite number of copies of a quantum pure state are presented. The optimal estima…

Unambiguous pure state identification without classical knowledge
A. Hayashi, M. Horibe, T. Hashimoto
We study how to unambiguously identify a given quantum pure state with one of the two reference pure states when no classical knowledge on the reference states is given but a certa…

Quantum pure-state identification
A. Hayashi, M. Horibe, T. Hashimoto
We address a problem of identifying a given pure state with one of two reference pure states, when no classical knowledge on the reference states is given, but a certain number of…
