Restless Tuneup of High-Fidelity Qubit Gates
M. A. Rol, C. C. Bultink, T. E. O'Brien +11
We present a tuneup protocol for qubit gates with tenfold speedup over traditional methods reliant on qubit initialization by energy relaxation. This speedup is achieved by constru…

Active resonator reset in the nonlinear dispersive regime of circuit QED
C. C. Bultink, M. A. Rol, T. E. O'Brien +8
We present two pulse schemes for actively depleting measurement photons from a readout resonator in the nonlinear dispersive regime of circuit QED. One method uses digital feedback…
