Description:
Author(s): Chang-shui Yu, Jia-sen Jin, Heng Fan, and He-shan Song We present a nondemolition quantum information processing task of probing the information of a class of quantum state. In this task, the information is extracted by some unitary evolution with the introduced probing qubit assisted, but the probed quantum state (density matrix) is undisturbed at any ... [Phys. Rev.
