Trapped ions are among the most promising systems for practical quantum computing (QC).
The basic requirements for universal QC have all been demonstrated with ions, and …

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 …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

Modern cavity quantum electrodynamics (cavity QED) illuminates the most fundamental
aspects of coherence and decoherence in quantum mechanics. Experiments on atoms in …

An outstanding goal in quantum information science is the faithful map** of quantum
information between a stable quantum memory and a reliable quantum communication …

Determining classically whether a coin is fair (head on one side, tail on the other) or fake
(heads or tails on both sides) requires an examination of each side. However, the analogous …

Precision metrology and quantum measurement often demand that matter be prepared in
well-defined quantum states for both internal and external degrees of freedom. Laser-cooled …

On the occasion of the hundredth anniversary of Albert Einstein's annus mirabilis, we reflect
on the development and current state of research in cavity quantum electrodynamics in the …

Two trapped ions that are kilometers apart can be entangled by the joint detection of two
photons, each coming from one of the ions, in a basis of entangled states. Such a detection …

The physics of optical vortices, also known as twisted light, is now a well-established and a
growing branch of optical physics with a number of important applications and significant …
