Distilling and protecting the single-photon entangled state
Lan Zhou, Yu-Bo Sheng
We propose two efficient entanglement concentration protocols (ECPs) for arbitrary less-entangled single-photon entanglement (SPE). Different from all the previous ECPs, these prot…
Cascaded noiseless linear amplification for single-photon state
Lan Zhou, Yu-Bo Sheng
Photon loss is one of the main obstacles in current long-distance quantum communications. The approach of noiseless linear amplification (NLA) is one of the powerful way to distill…
Quantum correlations of two qubits interacting with a macroscopic medium
Yan Liu, Jing Lu, Lan Zhou
We consider two particles of spin-1/2 interacting with a one-dimensional N-spin array, which is an exactly solvable model. The dynamics of entanglement and quantum discord (QD) of…
T-shaped Single-photon Router
Jing Lu, Z. H. Wang, Lan Zhou
We study the transport properties of a single photon scattered by a two-level system (TLS) in a T-shaped waveguide, which is made of two coupled-resonator waveguides (CRWs)--- an i…
Two-step complete polarization logic Bell-state analysis
Yu-Bo Sheng, Lan Zhou
Logic qubit entanglement, which is also called the concatenated Greenberger-Horne-Zeilinger (C-GHZ) state, is robust in practical noisy environment. In this paper, we will describe…
Bell-state Analysis for Logic Qubits Entanglement
Yu-Bo Sheng, Lan Zhou
Decoherence is one of the main obstacles in long-distance quantum communication. Recently, the theoretical work of Fröwis and W. Dür (Phys. Rev. Lett. \textbf{106}, 110402 (2011))…
