Device variability of Josephson junctions induced by interface roughness
Yu Zhu, Félix Beaudoin, Hong Guo
As quantum processors scale to large qubit numbers, device-to-device variability emerges as a critical challenge. Superconducting qubits are commonly realized using Al/AlO$_{\text{…
Frequency estimation under non-Markovian spatially correlated quantum noise: Restoring superclassical precision scaling
Francisco Riberi, Leigh M. Norris, Felix Beaudoin +1
We study the estimation precision attainable by entanglement-enhanced Ramsey interferometry in the presence of spatiotemporally correlated non-classical noise. Our analysis relies…
Two-qubit spectroscopy of spatiotemporally correlated quantum noise in superconducting qubits
Uwe von Lüpke, Félix Beaudoin, Leigh M. Norris +9
Noise that exhibits significant temporal and spatial correlations across multiple qubits can be especially harmful to both fault-tolerant quantum computation and quantum-enhanced m…
Extending comb-based spectral estimation to multiaxis quantum noise
Gerardo A. Paz-Silva, Leigh M. Norris, Félix Beaudoin +1
We show how to achieve full spectral characterization of general multiaxis additive noise. Our pulsed spectral estimation technique is based on sequence repetition and frequency-co…
Non-Gaussian noise spectroscopy with a superconducting qubit sensor
Youngkyu Sung, Félix Beaudoin, Leigh M. Norris +9
Accurate characterization of the noise influencing a quantum system of interest has far-reaching implications across quantum science, ranging from microscopic modeling of decoheren…
Ramsey Interferometry in Correlated Quantum Noise Environments
Félix Beaudoin, Leigh M. Norris, Lorenza Viola
We quantify the impact of spatio-temporally correlated Gaussian quantum noise on frequency estimation by Ramsey interferometry. While correlations in a classical noise environment…
