A laser pulse working around the intrinsic symmetry of light waves might modify quantum information, possibly assisting in moving closer to room temperature quantum computing.
The semiconductor nanosheets in the water-cooled copper mount turn an infrared laser pulse into an effectively unipolar terahertz pulse. The team says that their terahertz emitter could be made to fit inside a matchbox. Image credit: Christian Meineke, Huber Lab, University of Regensburg
