Abstract
The quantitative and qualitative investigation of the entangling power of passive optical elements was described. In an arbitrary multimode Gaussian state, the necessary and sufficient conditions required for the possibility of creating distillable entanglement were presented. The obtained conditions resulted in establishing a connection between the degree of squeezing of a Gaussian state and the degree of entanglement attainable by nonsqueezing operations.
