Noise cross-correlations from single-shot measurements
Juan S. Rojas-Arias, Peter Stano, Yi-Hsien Wu +3
We introduce a novel method that we call Single-Shot Cross-Spectroscopy (SSCS), for extracting the auto- and cross-power spectral densities of dephasing noise of a qubit pair. The…

Spin-qubit readout analysis based on a hidden Markov model
Maria Spethmann, Peter Stano, Daniel Loss
Across most qubit platforms, the readout fidelities do not keep up with the gate fidelities, and new ways to increase the readout fidelities are searched for. For semiconductor spi…
