Quasi-probability representations quantum theory applications quantum information science
2010/11/5
This article comprises a review of both the quasi-probability representations of infinite-dimensional quantum theory (including the Wigner function) and the more recently defined quasi-probability rep...
Manipulating quantum information on the controllable systems or subspaces
Manipulating quantum information controllable systems subspaces
2010/10/29
In this paper, we explore how to constructively manipulate quantum information on the controllable systems or subspaces. It is revealed that one can make full use of distinguished properties of Pauli ...
