An Exact Formula for Quantum Entropy Production along Quantum Trajectories

An Exact Formula for Quantum Entropy Production along Quantum Trajectories

We give an exact formula for the rate of change of the von Neumann entropy for the conditional state of a quantum system undergoing continuous measurement. Here we employ Paycha's Formula \cite{Paycha} which gives the noncommutative Taylor series development.
