▲ [19a-PA5-4] Mixed-Mode Quantum Squeezing in a Chain of Nonlinear Coupled Oscillator
キーワード：Quantum communication, Quantum information processing
Inevitable exhaustion of resources in classical technologies has been important in quantum computing, where the non-classical effect of squeezing becomes relevant for faster factorization of quantum algorithm. Studies of squeezed light indicate the occurrence of mixed-mode squeezing in multichannel waveguides to be of interests. This work reports squeezing in a chain of nonlinear coupled oscillator system designed using multichannel waveguides with the third-order nonlinear polarization. In the model, a four-channel nonlinear waveguide operates under Kerr effect; the waveguides being coupled via evanescent coupling. Results reveal the system as providing an effective way to manipulate squeezing, especially in the mixed-mode basis. As such, the system design using multichannel waveguides remains useful.
