Implement Quantum Random Walks with Linear Optics Elements
Zhi Zhao, Jiangfeng Du, Hui Li +3
The quantum random walk has drawn special interests because its remarkable features to the classical counterpart could lead to new quantum algorithms. In this paper, we propose a f…
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…
Deterministic and Highly Efficient Quantum Cryptography with Entangled Photon Pairs
Zhi Zhao, Tao Yang, Zeng-Bing Chen +2
We present a protocol for deterministic and highly efficient quantum cryptography with entangled photon pairs in a 4x4-dimentional Hilbert space. Two communicating parties, Alice a…
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…
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…
