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 …

Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

Electric-field noise near surfaces is a common problem in diverse areas of physics and a
limiting factor for many precision measurements. There are multiple mechanisms by which …

Advanced applications in optical metrology demand improved lasers with high spectral
purity, in form factors that are small and insensitive to environmental perturbations. While …

Single trapped ions represent elementary quantum systems that are well isolated from the
environment. They can be brought nearly to rest by laser cooling, and both their internal …

The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

Among the numerous types of architecture being explored for quantum computers are
systems utilizing ion traps, in which quantum bits (qubits) are formed from the electronic …

The superposition principle plays the most central role in all considerations of quantum
information, and in most of the" gedanken" experiments and even the paradoxes of quantum …

We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto
cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry …

Quantum computers hold the promise of solving certain computational tasks much more
efficiently than classical computers. We review recent experimental advances towards a …
