Quantum technologies are extremely sensitive to environmental disturbance. Control techniques inspired by classical systems engineering allow selective filtering of the noise spectrum, suppressing time-varying noise over defined frequency bands.Letter p825; News & Views p794 IMAGE: HARRISON BALL AND MICHAEL J.

Editorial

  • Many people around the world will remember 2014 as the year Brazil hosted the football World Cup. But for Brazil's science communities, the decisions made by the new government could leave scars much deeper than the semi-final defeat.

  • The ability to harness spin polarization is critical for many semiconductor spin devices. It now seems that spin–orbit coupling with locally broken symmetry can enable a giant spin polarization in a semiconductor that is otherwise inversion symmetric.

Review Article

  • Exciton–polaritons, resulting from the light–matter coupling between an exciton and a photon in a cavity, form Bose–Einstein-like condensates above a critical density. Various aspects of the physics of exciton–polariton condensates are now reviewed.
