Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

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 …

The manner in which states of some quantum systems become effectively classical is of
great significance for the foundations of quantum physics, as well as for problems of …

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 …

After they have interacted, quantum particles generally behave as a single nonseparable
entangled system. The concept of entanglement plays an essential role in quantum physics …

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 …

According to quantum mechanics, a physical system can be in any linear superposition of its
possible states. Although the validity of this principle is routinely validated for microscopic …

In 1978, while I was a postdoctoral fellow at MIT, I read a paper by Art Ashkin (1978) in
which he described how one might slow down an atomic beam of sodium using the radiation …

Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

When we were preparing the first edition of this book, the concept of de coherence was
known only to a minority of physicists. In the meantime, a wealth of contributions has …
