A research team led by Professor Takao Aoki worked together with researchers from the National Institute of Information and Communications Technology, Japan Telegraph and Telephone Corporation, Qatar Environment & Energy Research Institute, and Tokyo Medical and Dental University, and became the first to measure relatively large light shifts of superconducting flux qubits coupled with photons in superconducting LC oscillators.
(a) Circuit diagram. A superconducting flux qubit (red and black) and a superconducting LC oscillator (blue and black) are inductively coupled to each other by sharing an inductance (black).
Their study was published in Physical Review Letters on May 4, 2018.
