Quantum relative states

The photon-box experiment of the Haroche group Modelling based on three quantum rules Measuring photons without destroying them Stabilizing measurement-based feedback.. Model

For the states with constant mass, the corresponding units of action contribute to the quantum number k which characterises the angular action independent of the action associated

In this paper it is shown that diffusion equations for the state vector can be used effectively for the analysis of a quantum system in interaction with its

A nonlinear stochastic Schro¨dinger equation for pure states describing non-Markovian diffusion of quantum trajectories and compatible with non-Markovian master equations is

We show how, by a suitable complete set of measurements, the elements of the density matrices of the one- and two-particle states can be directly expressed in terms of the currents

We study relations between the ground-state energy of a quantum graph Hamiltonian with attractive δ coupling at the vertices and the graph geometry.. We derive a necessary and

This paper shows three results of such a type that are stronger in some sense than other ones because (a) they deal with models of quantum finite automata with very little
