The Gisin-Percival Stochastic Schrödinger Equation from Standard Quantum Filtering Theory

Published 3 Oct 2017 in quant-ph | (1710.01413v1)

Abstract: We show that the quantum state diffusion equation of Gisin and Percival, driven by complex Wiener noise, is equivalent up to a global stochastic phase to quantum trajectory models. With an appropriate feedback scheme, we set up an analogue continuous measurement model with exactly simulates the Gisin-Percival quantum state diffusion.
