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…

Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…

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…
