The optimal positive operator-valued measure for state discrimination
Wei Li, Shengmei Zhao
Evaluating the amount of information obtained from non-orthogonal quantum states is an important topic in the field of quantum information. The commonly used evaluation method is H…
Privacy amplification scheme based on composite coding
Wei Li, Shengmei Zhao
Privacy amplification is an indispensable step in the post-processing of quantum key distribution, which can be used to compress the redundancy of shared key and improve the securi…
Decoy-state round-robin differential-phase-shift quantum key distribution with source errors
Qian-Ping Mao, Le Wang, Sheng-Mei Zhao
As a promising quantum key distribution (QKD), most of the existing round-robin differential-phase-shift quantum key distribution (RRDPS-QKD) protocols have adopted the decoy-state…
Wave-Particle duality in Single-Photon Entanglement
Wei Li, Shengmei Zhao
The simplest single-photon entanglement is the entanglement of the vacuum state and the single-photon state between two path modes. The verification of the existence of single-phot…
Phase Matching Quantum Key Distribution based on Single-Photon Entanglement
Wei Li, Le Wang, Shengmei Zhao
Two time-reversal quantum key distribution (QKD) schemes are the quantum entanglement based device-independent (DI)-QKD and measurement-device-independent (MDI)-QKD. The recently p…
Multiple Pulses Phase-matching Quantum Key Distribution
Gang Chen, Le Wang, Wei Li +4
We propose a multiple pulses phase-matching quantum key distribution protocol (MPPM-QKD) to exceed the linear key rate bound and to achieve higher error tolerance. In our protocol,…
Thermal effects of the quantum states generated from the isomorphs of PPKTP crystal
Rui-Bo Jin, Guo-Qun Chen, Fabian Laudenbach +2
We theoretically and numerically investigate the temperature-dependent properties of the biphotons generated from four isomorphs of periodically poled (PPKTP):…
Efficient entanglement concentration for arbitrary less-entangled N-atom state
Lan Zhou
A recent paper (Phys. Rev. A 86, 034305 (2012)) proposed an entanglement concentration protocol (ECP) for less-entangled -atom GHZ state with the help of the photonic Faraday ro…
Optimal entanglement concentration for quantum dot and optical microcavities systems
Yu-Bo Sheng, Lan Zhou, Lei Wang +1
A recent paper [Chuan Wang, Phys. Rev. A \textbf{86}, 012323 (2012)] discussed an entanglement concentration protocol (ECP) for partially entangled electrons using a quantum dot an…
Efficient W state entanglement concentration using quantum-dot and optical microcavities
Yu-Bo Sheng, Lan Zhou, Chuan Wang +1
We present an entanglement concentration protocols (ECPs) for less-entangled W state with quantum-dot and microcavity coupled system. The present protocol uses the quantum nondemol…
Efficient two-step entanglement concentration for arbitrary W states
Yu-Bo Sheng, Lan Zhou, Sheng-Mei Zhao
We present two two-step practical entanglement concentration protocols (ECPs) for concentrating an arbitrary three-particle less-entangled W state into a maximally entangled W stat…
Efficient entanglement concentration for three-photon W states with parity check measurement
Yu-Bo Sheng, Lan Zhou, Sheng-Mei Zhao
We present an optimal entanglement concentration ECP for an arbitrary less-entangled W state. By two of the parties say Alice and Charlie performing one parity check measurements,…
Efficient single-photon-assisted entanglement concentration for partially entangled photon pairs
Yu-Bo Sheng, Lan Zhou, Sheng-Mei Zhao +1
We present two realistic entanglement concentration protocols (ECPs) for pure partially entangled photons. A partially entangled photon pair can be concentrated to a maximally enta…
