Practical scheme for the optimal measuremnet in quantum interferometric devices
Masahiro Takeoka, Masashi Ban, Masahide Sasaki
We apply a Kennedy-type detection scheme, which was originally proposed for a binary communications system, to interferometric sensing devices. We show that the minimum detectable…
Optimal parameter estimation of depolarizing channel
Masahide Sasaki, Masashi Ban, Stephen M. Barnett
We investigate strategies for estimating a depolarizing channel for a finite dimensional system. Our analysis addresses the double optimization problem of selecting the best input…
Continuous variable teleportation as a generalized thermalizing quantum channel
Masashi Ban, Masahide Sasaki, Masahiro Takeoka
A quantum channel is derived for continuous variable teleportation which is performed by means of an arbitrary entangled state and the standard protocol. When a Gaussian entangled…
