Stroboscopic qubit measurement with squeezed illumination
Andrew Eddins, Sydney Schreppler, David M. Toyli +6
Microwave squeezing represents the ultimate sensitivity frontier for superconducting qubit measurement. However, observation of enhancement has remained elusive, in part because in…
Effect of higher-order nonlinearities on amplification and squeezing in Josephson parametric amplifiers
Samuel Boutin, David M. Toyli, Aditya V. Venkatramani +3
Single-mode Josephson junction-based parametric amplifiers are often modeled as perfect amplifiers and squeezers. We show that, in practice, the gain, quantum efficiency, and outpu…
Engineering shallow spins in diamond with nitrogen delta-doping
Kenichi Ohno, F. Joseph Heremans, Lee C. Bassett +5
We demonstrate nanometer-precision depth control of nitrogen-vacancy (NV) center creation near the surface of synthetic diamond using an in situ nitrogen delta-doping technique dur…
