Classifying N-qubit Entanglement via Bell's Inequalities
Sixia Yu, Zeng-Bing Chen, Jian-Wei Pan +1
All the states of N qubits can be classified into N-1 entanglement classes from 2-entangled to N-entangled (fully entangled) states. Each class of entangled states is characterized…
Quantum Hall Effect in a Rotating Bose-Einstein Condensate: An Atomic Twin of the Electronic Brother?
Zeng-Bing Chen, Bo Zhao, Yong-De Zhang
We exploit the analogy with the quantum Hall (QH) effect for electrons to study the possible atomic QH states of a rapidly-rotating Bose-Einstein condensate. Actually, there is a n…
All-Versus-Nothing Violation of Local Realism for Two Entangled Photons
Zeng-Bing Chen, Jian-Wei Pan, Yong-De Zhang +2
It is shown that the Greenberger-Horne-Zeilinger theorem can be generalized to the case with only two entangled particles. The reasoning makes use of two photons which are maximall…
Calculation of entanglement for continious variable states
Huai-XIn Lu, Zeng-Bing Chen, Jian-Wei Pan +1
In this paper, we present a general formula for obtaining the reduced density opeator for any biparticle pure entangled state. Using this formula, we derive, in a compact form, the…
Quantum nonlocality and applications in quantum-information processing of hybrid entangled states
Zeng-Bing Chen, Guang Hou, Yong-De Zhang
The hybrid entangled states generated, e.g., in a trapped-ion or atom-cavity system, have exactly one ebit of entanglement, but are not maximally entangled. We demonstrate this by…
Linear Optics Quantum Communication over Long Distances
Zeng-Bing Chen, Huai-Xin Lu, Yong-De Zhang
We propose a feasible scheme for teleporting an arbitrary polarization state or entanglement of photons by requiring only single-photon (SP) sources, simple linear optical elements…
