“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

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

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 …

The generation of long-lived entanglement in optical atomic clocks is one of the main goals
of quantum metrology. Arrays of neutral atoms, where Rydberg-based interactions may …

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 …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …

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 …

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<?
