Physicists develop a novel quantum theory of light-induced matter

A team led by a physicist from City University of Hong Kong (CityU) recently developed a new quantum theory that explains the “light-induced phase” of matter and predicts its novel functionalities. The new theory has the potential to revolutionize the field of quantum photonics and quantum control at room temperature. It also opens the door to a variety of next-generation light-based applications, such as optical communications, quantum computing and light-harvesting technologies.
