文摘We introduce the entangled state representation to describe the four-wave mixing.We find that the four- wave 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.
