Breaking and making quantum money: toward a new quantum cryptographic protocol

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

Finally, our dimension witnesses can distinguish between classical and quantum systems of the same dimension, making them potentially useful for quantum information

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

The primitive BSP EXCHANGE send each state s for a pair (i, s) in tosend to the processor i and returns the set of states received from the other processors, together with the

We also note that given a well-known down- conversion process, the nonlocal phase of the daughter photon pair encodes the phase of the pump pulse and is invariant under local

The primitive BSP EXCHANGE send each state s for a pair (i, s) in tosend to the processor i and returns the set of states received from the other processors, together with the

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

The reduction of the persistent current as well as the onset of symmetry breaking, observed in the polarization and in the flux induced capacitance indicate that the coherence of
