Abstract

We study certain quantum states for which the PPT criterion is both sufficient and necessary for separability. A class of ntimes n bipartite mixed states is presented and the conditions of PPT for these states are derived. The separable pure state decompositions of these states are explicitly constructed when they are PPT.

Why This Paper Matters

  • This paper contributes to the Entanglement Theory & Quantum Correlations research area in the Quantum Articles archive.
  • It adds a 2013 reference point for readers tracking recent quantum research.
  • We study certain quantum states for which the PPT criterion is both sufficient and necessary for separability.
