Quantum langevin equation input and output
WebIn quantum probability, the Belavkin equation, also known as Belavkin-Schrödinger equation, quantum filtering equation, stochastic master equation, is a quantum stochastic differential equation describing the dynamics of a quantum system undergoing observation in continuous time. It was derived and henceforth studied by Viacheslav Belavkin in 1988. WebAug 1, 2014 · The factor of 2 in the δ-correlation and the square root in the Langevin equation are usually chosen for convenience. Details can be found in [ 12 ]. Since the drift and diffusion function have a physical interpretation, one could apply the model in Equation (2) to a particular system and define ad hoc the functional shape of both functions from …
