Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

The standard quantum limit bounds the precision of measurements that can be achieved by
ensembles of uncorrelated particles. Fundamentally, this limit arises from the non …

In 1935, Einstein, Podolsky, and Rosen (EPR) conceived a gedanken experiment which
became a cornerstone of quantum technology and still challenges our understanding of …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

We summarize important recent advances in quantum metrology, in connection to
experiments in cold gases, trapped cold atoms and photons. First we review simple …

Spinor Bose gases form a family of quantum fluids manifesting both magnetic order and<?
format?> superfluidity. This article reviews experimental and theoretical progress in …

The statistical error in any estimation can be reduced by repeating the measurement and
averaging the results. The central limit theorem implies that the reduction is proportional to …

This Colloquium gives an overview of recent theoretical and experimental progress in the
area of nonequilibrium dynamics of isolated quantum systems. There is particularly a focus …

The control of individual quantum systems promises a new technology for the 21st century-
quantum technology. This book is the first comprehensive treatment of modern quantum …
