Abstract

We have chosen the method of quantum trajectories [1] to simulate a system of two damped resonator modes, coupled by a nonlinear interaction Hamiltonian and pumped by coherent fields. Balanced homodyne detection of the output field has been included in the simulations for two reasons: it generates the homodyne signal which could be observed in an experiment, and it also ensures that every individual trajectory will remain localized in phase space. A quasi-simultaneous measurement of both the X and Y quadrature is implemented by changing the phase of the local oscillator at a high rate. The simulation code is optimized for and runs on a Cray J916/6-1024.
