Reexamination of optimal quantum state estimation of pure states
A. Hayashi, T. Hashimoto, M. Horibe
A direct derivation is given for the optimal mean fidelity of quantum state estimation of a d-dimensional unknown pure state with its N copies given as input, which was first obtai…

Solution to the King's problem with observables being not mutually complementary
Minoru Horibe, Akihisa Hayashi, Takaaki Hashimoto
We investigate the King's problem of the measurement of operators instead of the three Cartesian components , and $σ_…

Extended Quantum Color Coding
A. Hayashi, T. Hashimoto, M. Horibe
The quantum color coding scheme proposed by Korff and Kempe (quant-ph/0405086) is easily extended so that the color coding quantum system is allowed to be entangled with an extra a…
