On the quantum polarization and entanglement of superposition of two two-mode coherent states
arXiv:0807.0037
Abstract
This work discuss the entanglement and quantum polarization of superpositions of two-mode coherent states. We use the concurrence to measure their entanglements and the quantum Stokes parameters and the Q function in order to analyze their polarization and degree of polarization.
