Protecting sing-photon multi-mode W state from photon loss
Yu-Bo Sheng, Yang Ou-Yang, Lan Zhou +1
Single-photon entanglement is of major importance in current quantum communications. However, it is sensitive to photon loss. In this paper, we discuss the protection of single-pho…

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 -particle state concentration with different parity check gates
Yu-Bo Sheng, Lan Zhou, Yu-Wei Sheng +1
We present an universal way to concentrate an arbitrary -particle less-entangled state into a maximally entangled state with different parity check gates. It comprises t…
