van Dijk, J.P.G. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author)Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) and their performance is required to demonstrate such quantum supremacy. While scaling up the underlying quantum processor is extremely challenging, building the...journal article 2019

(author), Schouten, R.N. (author), DiCarlo, L. (author)We present two pulse schemes to actively deplete measurement photons from a readout resonator in the nonlinear dispersive regime of circuit QED. One method uses digital feedback conditioned on the measurement outcome, while the other is unconditional. In the absence of analytic forms and symmetries to exploit in this nonlinear regime, the...journal article 2016
