The method is scalable for many quantum-field problems and therefore allows first-principles simulations of multimode bosonic fields undergoing continuous measurement, such as those controlled by measurement-based feedback. As examples, we demonstrate a 53-fold speed increase for the simulation of the feedback cooling of a single trapped particle, and the feedback cooling of a quantum field with 32 modes, which would be impractical using previous brute force methods.Keywords: Bosonic fields; Brute force; Continuous measurements; Feedback cooling; First-principles simulations; Master equations; Measurement-based; Multimodes; Quantum field; Speed increase; Stochastic simulations; Trapped particle; Cooling; Stochastic models200910.1103/PhysRevA.80.0136062016-02-24
