    "abstract": "We discuss a non-linear stochastic master equation that governs the\ntime-evolution of the estimated quantum state. Its differential evolution\ncorresponds to the infinitesimal updates that depend on the time-continuous\nmeasurement of the true quantum state. The new stochastic master equation\ncouples to the two standard stochastic differential equations of\ntime-continuous quantum measurement. For the first time, we can prove that the\ncalculated estimate almost always converges to the true state, also at\nlow-efficiency measurements. We show that our single-state theory can be\nadapted to weak continuous ensemble measurements as well.",
