Non-Gaussian Noise Spectroscopy With Superconducting Qubits. Part 2: Experiment

ORAL

Abstract

Most quantum control and quantum error-correction protocols assume that the noise causing decoherence is described by Gaussian statistics. However, the Gaussianity assumption breaks down when the system is strongly coupled to a sparse environment, such as those consisting of a few two-state fluctuators. Here, we implement open-loop quantum control protocols to characterize both Gaussian and non-Gaussian dephasing processes in superconducting qubits.
