Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

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

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 …

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 …

Understanding relaxation processes is an important unsolved problem in many areas of
physics. A key challenge is the scarcity of experimental tools for the characterization of …

We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

The relaxation of isolated quantum many-body systems is a major unsolved problem
connecting statistical and quantum physics. Studying such relaxation processes remains a …

We demonstrate the creation of entangled, spin-squeezed states using a collective, or joint,
measurement and real-time feedback. The pseudospin state of an ensemble of N= 5× 10 4 …

We review the recent progress in the understanding of the relaxation of isolated near-
integrable quantum many-body systems. Focusing on prethermalization and universal …

Modern quantum technologies in the fields of quantum computing, quantum simulation, and
quantum metrology require the creation and control of large ensembles of entangled …
