Abstract
We analyze the entanglement condition of a new kind of non-Gaussian quantum state, which is prepared by photon number subtraction from a two mode Gaussian state. Fock space criterion and Shchukin-Vogel criterion are applied and the results are compared. Two kinds of the original Gaussian states are utilized. Their photon subtracted states have different entanglement properties.
