Disentangling the sources of ionizing radiation in superconducting qubits
L. Cardani, I. Colantoni, A. Cruciani +27
Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we mea…
Navigating the noise-depth tradeoff in adiabatic quantum circuits
Daniel Azses, Maxime Dupont, Bram Evert +2
Adiabatic quantum algorithms solve computational problems by slowly evolving a trivial state to the desired solution. On an ideal quantum computer, the solution quality improves mo…
Multi-mode Analysis of Surface Losses in a Superconducting Microwave Resonator in High Magnetic Fields
T. Braine, G. Rybka, A. A. Baker +6
This paper reports on a surface impedance measurement of a niobium titanium superconducting radio frequency (SRF) cavity in a magnetic field (up to ). A novel method i…
Characterization of Nb films for superconducting qubits using phase boundary measurements
Kevin M. Ryan, Carlos G. Torres-Castanedo, Dominic P. Goronzy +8
Continued advances in superconducting qubit performance require more detailed understandings of the many sources of decoherence. Within these devices, two-level systems arise due t…
Quasiparticle spectroscopy, transport, and magnetic properties of Nb films used in superconducting transmon qubits
Kamal R. Joshi, Sunil Ghimire, Makariy A. Tanatar +10
Niobium thin films on silicon substrate used in the fabrication of superconducting qubits have been characterized using scanning and transmission electron microscopy, electrical tr…
Visualizing heterogeneous dipole fields by terahertz light coupling in individual nano-junctions used in transmon qubits
R. H. J. Kim, J. M. Park, S. Haeuser +12
The fundamental challenge underlying superconducting quantum computing is to characterize heterogeneity and disorder in the underlying quantum circuits. These nonuniform distributi…
