キーワード:Squeezing, Quantum correlation, Quantum States

The effects of squeezing have been of great importance in quantum computing, as evidenced in the studies of squeezed light presented in the literature. The present work discusses on the possibility of enhancing squeezing using nonlinear coupler utilizing different operating frequencies of the input modes. In our two-channel model, one of the channels contains the fundamental mode, whereas the other one confines the next two higher-order modes. Here we examine numerically the effect of frequency mismatch on the dynamics of the generated squeezed light. The results reveal the system as providing an effective way to obtain enhanced squeezing. Such interaction scheme can be potentially useful to further improve squeezing in other configurations like multichannel- Kerr and second- harmonic generation.
