The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Quantum phase transitions (QPTs) are usually associated with many-body systems in the
thermodynamic limit when their ground states show abrupt changes at zero temperature with …

Methods for, and limitations to, the generation of entangled states of trapped atomic ions are
examined. As much as possible, state manipulations are described in terms of quantum …

A" Schrödinger cat''-like state of matter was generated at the single atom level. A trapped
9Be+ ion was laser-cooled to the zero-point energy and then prepared in a superposition of …

We report the creation of thermal, Fock, coherent, and squeezed states of motion of a
harmonically bound 9 Be+ ion. The last three states are coherently prepared from an ion …

This is the third, revised and extended edition of the acknowledged" Lectures on Quantum
Optics" by W. Vogel and D.-G. Welsch. It offers theoretical concepts of quantum optics, with …

Nonclassical states of light are of fundamental importance in quantum optics. The properties
of these states are due to the quantal nature of the electromagnetic field. In recent years …

We consider a class of nonlinear coherent states, which are right-hand eigenstates of the
product of the boson annihilation operator and a nonlinear function of the number operator …

We propose a scheme for generating even and odd coherent states of the motion of a
trapped ion via laser excitation of two vibronic transitions. These quantum superposition …

We discuss different ways of generating entanglement in the original picture of circuit QED
(XcQED) and several restrictions that arise in the context of a large-scale quantum …
