Quantum control of a linear oscillator using a static dispersive coupling to a nonlinear ancilla
underpins a wide variety of experiments in circuit QED. Extending this control to more than …

Spins and oscillators are foundational to much of physics and applied sciences. For
quantum information, a spin 1/2 exemplifies the most basic unit, a qubit. High angular …

We systematically investigate the influence of the fabrication process on dielectric loss in
aluminum-on-silicon superconducting coplanar waveguide resonators with internal quality …

Studies of strongly nonlinear dynamical systems such as turbulent flows call for superior
