Optimal estimation of an observable's expectation value for pure states for general measure of deviation
Minoru Horibe, Akihisa Hayashi, Takaaki Hashimoto
We investigate the optimal estimation of quantum expectation value of a physical observable, which minimizes a mean error with respect to general measure of deviation, when a finit…

Stationary quantum Markov process for the Wigner function
T. Hashimoto, M. Horibe, A. Hayashi
As a stochastic model for quantum mechanics we present a stationary quantum Markov process for the time evolution of the Wigner function on a lattice phase space Z_N x Z_N with N o…
