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 …

Interactions govern the flow of information and the formation of correlations between
constituents of many-body quantum systems, dictating phases of matter found in nature and …

Linear quantum measurements with independent particles are bounded by the standard
quantum limit, which limits the precision achievable in estimating unknown phase …

An ensemble of atoms can operate as a quantum sensor by placing atoms in a
superposition of two different states. Upon measurement of the sensor, each atom is …

State-of-the-art atomic clocks are based on the precise detection of the energy difference
between two atomic levels, which is measured in terms of the quantum phase accumulated …

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 …

Quantum scrambling describes the spreading of information into many degrees of freedom
in quantum systems, such that the information is no longer accessible locally but becomes …

Quantum simulation of spin models can provide insight into problems that are difficult or
impossible to study with classical computers. Trapped ions are an established platform for …
