Edge modes are a key feature of topological materials, but their propagation is difficult to directly observe in condensed matter systems. The controlled injection and propagation of chiral edge modes has now been shown in a rotating ultracold gas.

The dimensionality of a many-body system strongly impacts its physical behaviour. Now, a crossover from 1D to 2D has been observed in the Bose–Einstein condensate of a photon gas.

Approximate—rather than exact—quantum error correction is a useful but relatively unexplored idea in quantum computing and many-body physics. A theoretical framework has now been established based on connections with quantum circuit complexity.

Magnetic phases that are stabilized by quantum fluctuations in low dimensions are rare. A thickness-dependent crossover from three-dimensional antiferromagnetism to a two-dimensional vestigial nematic state that is driven by fluctuations has now been observed.

For solid-state qubits, the material environment hosts sources of errors that vary in time and space. This systematic analysis of errors affecting high-fidelity two-qubit gates in silicon can inform the design of large-scale quantum computers.

Non-classical states with a large, definite number of photons can now be produced in a superconducting cavity and used for quantum-enhanced sensing.

Measurements pervade winemaking, from the size of vineyards to the taste in your mouth. Stefanie Reichert gives us the tour.

In light of the recent Olympic and upcoming Paralympic Summer Games in Paris, we take a closer look at the physics of sports and how it helps athletes improve their performance.

This year marks the hundredth anniversary of Satyendra Nath Bose’s paper that stimulated the study of quantum statistics. We take this opportunity to celebrate the physics of bosons.

High harmonic generation has long been successfully described using the semi-classical three-step model. However, recent progress has introduced a quantum optical formulation, exposing the limitations of the semi-classical picture.
