Improving entanglement of even entangled coherent states via superposition of number-conserving operations

Improving entanglement of even entangled coherent states via superposition of number-conserving operations

A scheme for improving entanglement is proposed by repeatedly performing number-conserving generalized superposition of products (GSP) operation, i.e., saa†+ta†amwith s2+t2=1,on each modes of even entangled coherent state (EECS). Both Einstein–Podolsky–Rosen (EPR) correlation and concurrence are use...
