All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

We propose a review of recent developments on entanglement and nonclassical effects in
collective two-atom systems and present a uniform physical picture of the many predicted …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

An atom that couples to two distinct leaky optical cavities is driven by an external optical
white noise field. We describe how entanglement between the light fields sustained by two …

We model the behavior of an ion trap with all ions driven simultaneously and coupled
collectively to a heat bath. The equations for this system are similar to the irreversible …

The concept of time delayed creation of entanglement by the dissipative process of
spontaneous emission is investigated. A threshold effect for the creation of entanglement is …

We present a protocol that allows the generation of a maximally entangled state between
individual atoms held in spatially separate cavities. Assuming perfect detectors and …

Up to now, the lifetime of experimentally demonstrated entangled states has been limited
due to their fragility under decoherence and dissipation. Therefore, they are created under …

We discuss the creation of entanglement between two two-level atoms in the dissipative
process of spontaneous emission. It is shown that spontaneous emission can lead to a …

In this tutorial we review the physical implementation of quantum computing using a system
of cold trapped ions. We discuss systematically all the aspects for making the …
