Scientists use Light to Accelerate Supercurrents, access Forbidden Light, Quantum World

This illustration shows light wave acceleration of supercurrents, which gives researchers access to a new class of quantum phenomena. That access could chart a path forward for practical quantum computing, sensing and communicating applications. Larger image. Image courtesy of Jigang Wang.

Scientists are using light waves to accelerate supercurrents and access the unique properties of the quantum world, including forbidden light emissions that one day could be applied to high-speed, quantum computers, communications and other technologies.

The scientists have seen unexpected things in supercurrents – electricity that moves through materials without resistance, usually at super cold temperatures – that break symmetry and are supposed to be forbidden by the conventional laws of physic...
