“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 …

A particular strength of ultracold quantum gases is the range of versatile detection methods
that are available. As they are based on atom–light interactions, the whole quantum optics …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

We propose an approach to quantum phase estimation that can attain precision near the
Heisenberg limit without requiring single-particle-resolved state detection. We show that the …

Quantum metrology exploits entangled states of particles to improve sensing precision
beyond the limit achievable with uncorrelated particles. All previous methods required …

We discuss the experimental engineering of model systems for the description of quantum
electrodynamics (QED) in one spatial dimension via a mixture of bosonic23Na and …

Useful quantum metrology requires nonclassical states with a high particle number and
(close to) the optimal exploitation of the state's quantum correlations. Unfortunately, the …

The recent advances in single atom detection and manipulation in experiments with
ultracold quantum gases are reviewed. The discussion starts with the basic principles of …

Time-reversed evolution has substantial implications in physics, including applications in
refocusing of classical waves or spins and fundamental studies such as quantum …
