On-demand microwave generator of shaped single photons
P. Forn-Díaz, C. W. Warren, C. W. S. Chang +2
We demonstrate the full functionality of a circuit that generates single microwave photons on demand, with a wave packet that can be modulated with a near-arbitrary shape. We achie…

Observation of the Bloch-Siegert Shift in a Qubit-Oscillator System in the Ultrastrong Coupling Regime
P. Forn-Díaz, J. Lisenfeld, D. Marcos +4
We measure the dispersive energy-level shift of an resonator magnetically coupled to a superconducting qubit, which clearly shows that our system operates in the ultrastrong c…

Strong Coupling of a Quantum Oscillator to a Flux Qubit at its Symmetry Point
A. Fedorov, A. K. Feofanov, P. Macha +3
A flux qubit biased at its symmetry point shows a minimum in the energy splitting (the gap), providing protection against flux noise. We have fabricated a qubit whose gap can be tu…
