Despite its technological importance, there remain gaps in our understanding of silicon’s electronic behaviour, especially at low temperatures. Measurements close to a metal–insulator transition show signs of a collective many-body quantum state.

Individual atoms trapped by optical ‘tweezers’ are emerging as a promising computational platform.

A scheme for converting qubits between two different representations, discrete and continuous variables, paves the way for more-efficient quantum networks.

Enhancement of laser energy conversion into X-rays is obtained using a target made by entwined carbon nanotubes.

Strongly laser-driven quantum correlated many-body systems lead to the generation of light with exotic quantum features — the quantumness of a many-body system is imprinted on the state of the emitted light.

Two studies explore strongly correlated states of Bose–Fermi excitonic complexes realized in two distinct solid-state platforms, setting the stage for tabletop quantum simulators.
