Conditions for Local Entanglement Manipulation from Pure States to Mixed States

Lin-Mei Liang, Ping‐Xing Chen, Cheng-Zu Li +1 more

We discuss the transformation from pure states to mixed states in a bipartite system H A ⊗ H B and provide the sufficient condition for this transformation. We also provide a necessary and sufficient condition for one class of this transformation. Meanwhile, the method of realization for the transformation from pure states to mixed states is also present. Furthermore, we briefly discuss the application.

Purification of two-qubit mixed states

E. Jané

We find the necessary and sufficient condition under which two two-qubit mixed states can be purified into a pure maximally entangled state by local operations and classical communication. The optimal protocol for such transformation is obtained. This result leads to a necessary and sufficient condition for the exact purification of $n$ copies of a two-qubit state.
