Description
It is possible to couple quantum and classical variables consistently (i.e. without paradoxes like faster than light signalling) provided one accepts a certain amount of stochasticity. This is useful, for example, if one wants to entertain the possibility that spacetime is fundamentally classical. These hybrid dynamics are not trivial (like meanfield) but they are nothing fancy either, and one way to construct them is via “measurement and feedback”. I will explain how this is concretely done, and how the construction gives some intuition about the type of physics one can expect. I’ll also try to mention some of the challenges in applying this formalism to gravity.
