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…
Simple, robust and on-demand generation of single and correlated photons
Sankar Raman Sathyamoorthy, Andreas Bengtsson, Steven Bens +3
We propose two different setups to generate single photons on demand using an atom in front of a mirror, along with either a beam-splitter or a tunable coupling. We show that photo…
Detecting itinerant single microwave photons
Sankar Raman Sathyamoorthy, Thomas M. Stace, Göran Johansson
Single photon detectors are fundamental tools of investigation in quantum optics and play a central role in measurement theory and quantum informatics. Photodetectors based on diff…
Quantum nondemolition detection of a propagating microwave photon
Sankar R. Sathyamoorthy, L. Tornberg, Anton F. Kockum +5
The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement.…
Giant Cross Kerr Effect for Propagating Microwaves Induced by an Artificial Atom
Io-Chun Hoi, C. M. Wilson, Göran Johansson +4
We have investigated the cross Kerr phase shift of propagating microwave fields strongly coupled to an artificial atom. The artificial atom is a superconducting transmon qubit in a…
