Researchers at the National Institute of Information and Communications Technology (NICT), in collaboration with researchers at the NTT Basic Research Laboratories, Nippon Telegraph and Telephone Corporation (NTT-BRL) and the Qatar Environment and Energy Research Institute (QEERI) have discovered qualitatively new lowest energy state of a superconducting artificial atom dressed with virtual photons. The discovery was made using spectroscopic measurements on an artificial atom that is very strongly coupled to the electromagnetic field inside a superconducting resonator. This result provides a new platform to investigate the interaction between light and matter at a fundamental level, helps understand quantum phase transitions and provides a route to applications of non-classical light such as Schrödinger cat states. It may contribute to the development of quantum technologies in areas such as quantum communication, quantum simulation and computation, or quantum metrology.
