| Abstract: | This work discusses the entanglement and quantum polarization of superpositions of two-mode coherent states of the types |ψ1〉 = N1(|α, β〉 + |β, α〉) and |ψ2〉 = N2(|−α, −α〉 + |α, α〉). 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. |
