Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator
Quantum information transfer nitrogen-vacancy centers coupled whispering-gallery microresonator
2010/11/9
We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (NV) centers coupled to a high-Q microspherical resonator. We show that, base...
Comparing globalness of bipartite unitary operations acting on quantum information: delocalization power, entanglement cost, and entangling power
Comparing globalness bipartite unitary operations acting quantum information delocalization power entanglement cost entangling power
2010/11/8
We compare three different characterizations of the globalness of bipartite unitary operations based on different tasks, namely, delocalization power, entanglement cost for LOCC implementation, and e...

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 ...

Temporal Leggett-Garg-Bell inequalities for sequential multi-time actions in quantum information processing, and a re-definition of Macroscopic Realism
Temporal Leggett-Garg-Bell inequalities sequential multi-time actions quantum information processing a re-definition Macroscopic Realism
2010/10/19
The usual formulation of Macrorealism is recast to make this notion fully concurrent with the basic ideas behind classical physics. The assumption of non-invasiveness of measurements is dropped. Inste...
Superconducting nanowire single photon detectors for quantum information and communications
Superconducting nanowire single photon detectors quantum key distribution Gifford-McMahon
2010/3/10
Superconducting nanowire single photon detectors (SNSPD or SSPD) are highly promising devices in the growing field of quantum information and communications technology. We have developed a practical S...
