Researchers at the University of Waterloo’s Institute for Quantum Computing (IQC) recorded an interaction between light and matter 10X larger than previously seen. The strength of the interaction between photons and a qubit was so large that it opens the door to a realm of physics and applications unattainable until now. “We are enabling the investigation of light-matter interactions in a new domain in quantum optics,” said Pol Forn-Diaz, a postdoctoral fellow at IQC. “The possibilities are exciting because our circuit could potentially act as a quantum simulator to study other interesting quantum systems in nature.”
The ultrastrong coupling between...
