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…

Instruments and mutual entropies in quantum information
Alberto Barchielli, Giancarlo Lupieri
General quantum measurements are represented by instruments. In this paper the mathematical formalization is given of the idea that an instrument is a channel which accepts a quant…

Instrumental processes, entropies, information in quantum continual measurements
Alberto Barchielli, Giancarlo Lupieri
In this paper we will give a short presentation of the quantum Levy-Khinchin formula and of the formulation of quantum continual measurements based on stochastic differential equat…
