Entangled State Representation for Four-Wave Mixing

We introduce the entangled state representation to describe the four-wave mixing. We find that the fourwave mixing operator, which engenders the correct input-output field transformation, has a natural representation in the entangled state representation. In this way, we see that the four-wave mixin...

Description
Summary:We introduce the entangled state representation to describe the four-wave mixing. We find that the fourwave mixing operator, which engenders the correct input-output field transformation, has a natural representation in the entangled state representation. In this way, we see that the four-wave mixing process not only involves squeezing but also is an entanglement process. This analysis brings convenience to the calculation of quadrature-amplitude measurement for the output state of four-wave mixing process.
