Impossibility Criterion for Obtaining Pure Entangled States From Mixed States By Purifying Protocols
Ping-Xing Chen, Lin-Mei Liang, Cheng-Zu Li +1
Purifying noisy entanglement is a protocol which can increase the entanglement of a mixed state (as a source)at expense of the entanglement of others(as an ancilla)by collective me…
A Necessary And Sufficient Condition of Distillability with unite fidelity from Finite Copies of a Mixed State: The Most Efficient Purification Protocol
Ping-Xing Chen, Lin-Mei Liang, Cheng-Zu Li +1
It is well known that any entangled mixed state in systems can be purified via infinite copies of the mixed state. But can one distill a pure maximally entangled state…
Necessary And Sufficient Condition of Separability of Any System
Ping-Xing Chen, Lin-Mei Liang, Cheng-Zu Li +1
The necessary and sufficient condition of separability of a mixed state of any systems is presented, which is practical in judging the separability of a mixed state. This paper als…
