Nonequilibrium heat transport and work with a single artificial atom coupled to a waveguide: emission without external driving
Yong Lu, Neill Lambert, Anton Frisk Kockum +5
We observe the continuous emission of photons into a waveguide from a superconducting qubit without the application of an external drive. To explain this observation, we build a tw…
Quantum efficiency, purity and stability of a tunable, narrowband microwave single-photon source
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +7
We demonstrate an on-demand source of microwave single photons with 71--99\% intrinsic quantum efficiency. The source is narrowband (300\unite{kHz}) and tuneable over a 600 MHz ran…
Propagating Wigner-Negative States Generated from the Steady-State Emission of a Superconducting Qubit
Yong Lu, Ingrid Strandberg, Fernando Quijandría +3
We experimentally demonstrate the steady-state generation of propagating Wigner-negative states from a continuously driven superconducting qubit. We reconstruct the Wigner function…
