Single atoms and molecules can be trapped in tightly focused beams of light that form
'optical tweezers', affording exquisite capabilities for the control and detection of individual …

After many years of development of the basic tools, quantum simulation with ultracold atoms
has now reached the level of maturity at which it can be used to investigate complex …

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 …

Arrays of optically trapped atoms excited to Rydberg states have recently emerged as a
competitive physical platform for quantum simulation and computing, where high-fidelity …

Ultracold polar molecules are promising candidate qubits for quantum computing and
quantum simulations. Their long-lived molecular rotational states form robust qubits, and the …

We use the resonant dipole-dipole interaction between Rydberg atoms and a periodic
external microwave field to engineer XXZ spin Hamiltonians with tunable anisotropies. The …

We report the implementation of universal two-and three-qubit entangling gates on neutral-
atom qubits encoded in long-lived hyperfine ground states. The gates are mediated by …

The concept of topological phases is a powerful framework for characterizing ground states
of quantum many-body systems that goes beyond the paradigm of symmetry breaking …

This topical review addresses how Rydberg atoms can serve as building blocks for
emerging quantum technologies. Whereas the fabrication of large numbers of artificial …

A great challenge in current quantum science and technology research is to realize artificial
systems of a large number of individually controlled quantum bits for applications in …
