Quantum stochastic calculus, operation valued stochastic processes, and continual measurements in quantum mechanics
The physical idea of a continual observation on a quantum system has been recently formalized by means of the concept of operation valued stochastic process (OVSP). In this article, it is shown howExpand

Quantum stochastic models of two-level atoms and electromagnetic cross sections
Quantum stochastic differential equations have been used to describe the dynamics of an atom interacting with the electromagnetic field via absorption/emission processes. Here, by using the fullExpand

Instruments and mutual entropies in quantum information
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 quantum state as inputExpand

Instruments and channels in quantum information theory
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 the instrument as aExpand

An analogue of Hunt's representation theorem in quantum probability
In quantum mechanics certain operator-valued measures are introduced, called instruments, which are an analogue of the probability measures of classical probability theory. As in the classical case,Expand

A quantum analogue of Hunt's representation theorem for the generator of convolution semigroups on Lie groups
SummaryIn quantum mechanics certain operator-valued measures are introduced, called instruments, which are an analogue of the probability measures of classical probability theory. As in the classicalExpand
