Evolution of Flux Noise in Superconducting Qubits with Weak Magnetic Fields
David A. Rower, Lamia Ateshian, Lauren H. Li +18
The microscopic origin of magnetic flux noise in superconducting circuits has remained an open question for several decades despite extensive experimental and theoretical inv…
Hexagonal Boron Nitride (hBN) as a Low-loss Dielectric for Superconducting Quantum Circuits and Qubits
Joel I-J. Wang, Megan A. Yamoah, Qing Li +19
Dielectrics with low loss at microwave frequencies are imperative for high-coherence solid-state quantum computing platforms. We study the dielectric loss of hexagonal boron nitrid…
Tunneling spectroscopy of graphene nanodevices coupled to large-gap superconductors
Joel I-Jan Wang, Landry Bretheau, Daniel Rodan-Legrain +4
We performed tunneling spectroscopy measurements of graphene coupled to niobium/niobium-nitride superconducting electrodes. Due to the proximity effect, the graphene density of sta…
Quantum coherent control of a hybrid superconducting circuit made with graphene-based van der Waals heterostructures
Joel I-Jan Wang, Daniel Rodan-Legrain, Landry Bretheau +14
Quantum coherence and control is foundational to the science and engineering of quantum systems. In van der Waals (vdW) materials, the collective coherent behavior of carriers has…
Tunnelling Spectroscopy of Andreev States in Graphene
Landry Bretheau, Joel I-Jan Wang, Riccardo Pisoni +3
A normal conductor placed in good contact with a superconductor can inherit its remarkable electronic properties. This proximity effect microscopically originates from the formatio…
