Concentration for unknown atomic entangled states via cavity decay
Zhuo-Liang Cao, Li-Hua Zhang, Ming Yang
We present a physical scheme for entanglement concentration of unknown atomic entangled states via cavity decay. In the scheme, the atomic state is used as stationary qubit and pho…
Improving the security of multiparty quantum secret sharing against Trojan horse attack
Fu-Guo Deng, Xi-Han Li, Hong-Yu Zhou +1
We analyzed the security of the multiparty quantum secret sharing (MQSS) protocol recently proposed by Zhang, Li and Man [Phys. Rev. A \textbf{71}, 044301 (2005)] and found that th…
Scheme for deterministic Bell-state-measurement-free quantum teleportation
Ming Yang, Zhuo-Liang Cao
A deterministic teleportation scheme for unknown atomic states is proposed in cavity QED. The Bell state measurement is not needed in the teleportation process, and the success pro…
Entanglement concentration for unknown atomic entangled states via entanglement swapping
Ming Yang, Yan Zhao, Wei Song +1
An entanglement concentration scheme for unknown atomic entanglement states is proposed via entanglement swapping in cavity QED. Because the interaction used here is a large-detune…
Entanglement swapping without joint Measurement
Ming Yang, Wei Song, Zhuo-Liang Cao
We propose an entanglement swapping scheme in cavity QED. In the scheme, the previously used joint measurement is not needed. The entanglement swapping in our proposal is a non-pos…
Generation of pure, ionic entangled states via linear optics
Ming Yang, Zhuo-Liang Cao
In this paper, we propose a novel scheme to generate two-ion maximally entangled states from either pure product states or mixed states using linear optics. Our new scheme is mainl…
