Dynamics of transient cat-states in degenerate parametric oscillation with and without nonlinear Kerr interactions

R. Y. Teh, F. -X. Sun, R. E. S. Polkinghorne +4

A cat-state is formed as the steady-state solution for the signal mode of an ideal, degenerate parametric oscillator, in the limit of negligible single-photon signal loss. In the p…
