Quantum Discord and Entanglement in Quasi-Werner States Based on
Bipartite Superposed Coherent States
   [PDF]

Ajay K Maurya, Manoj K Mishra, Hari Prakash
Recently, the authors [arXiv quant-ph 1209.3706] studied quantum discord for Werner mixed states based on the four entangled coherent states, which are used for quantum teleportation of single qubit information encoded in superposed coherent state and compared it with entanglement of formation. In the present paper, we consider two more general bipartite superposed coherent states and get two quasi-Werner states. We study quantum discord and entanglement of formation for these states and compare them.
