Abstract
Entanglement for continuous variable states opens up an avenue for experimental utilization of the entanglement properties of quantum physics very easily. Non- Gaussian continuous variable state improves the efficiency and robustness of a quantum teleportation and communication. Thus, it is important to understand the entanglement properties of non-Gaussian states. For a class of non-Gaussian continuous variable states, we derive a general criterion for SU(2) operators which incidentally coincides with the work of Agarwal and Biswas and another entanglement criteria for SU(1,1) operators for a two-mode non-Gaussian state using uncertainty relation and Cauchy-Schwarz inequality.
