Measurements continuous in time and a posteriori states in quantum
A. Barchielli, V. P. Belavkin
Measurements continuous in time were consistently introduced in quantum mechanics and applications worked out, mainly in quantum optics. In this context a quantum filtering theory…

Entropic bounds and continual measurements
Alberto Barchielli, Giancarlo Lupieri
Some bounds on the entropic informational quantities related to a quantum continual measurement are obtained and the time dependencies of these quantities are studied.

Quantum measurements and entropic bounds on information transmission
Alberto Barchielli, Giancarlo Lupieri
While a positive operator valued measure gives the probabilities in a quantum measurement, an instrument gives both the probabilities and the a posteriori states. By interpreting t…
