I'm not familiar with the Belavkin equation, so I can't answer that part without lots of study, but here's what I would look for: consider a more complete model (one that includes measurement equipment and recording devices in the quantum system) that uses unitary time-evolution together with periodic applications of the projection rule to the recording devices (not to the particle). Maybe some kind of period $\to 0$ limit gives something like the Belavkin equation for the particle itself. I don't know if it does, but that's what I would look for. | |

| Sep 10, 2020 at 9:29 | comment | added | Roman | Thank you for the answer. Is there a way to connect your explanation with Belavkin equation ( en.wikipedia.org/wiki/Belavkin_equation). It seems to be relevant since it also describes a continuous observation of position (according to the linked wikipedia page). How is it connected to your approach? | |

Changed a value-judgement word to a more objective word
