Semiclassical entanglement analyses in a non-degenerate parametric oscillator (NDPO)
Daniel B. Erenso, Joshua Dodson, K. Fesseha · The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting · 2013
The entanglement of the intracavity photons in subthreshold NDPO coupled to a squeezed vacuum is studied using the von-neumann entropy (VNE). The VNE is calculated in terms of the Q-function representation for the density operator.
