Leakage benchmarking with decohering subgroups in the presence of preparation and measurement errors
Shawn Geller, Tongyu Zhao, Alex Kwiatkowski +3
A common problem with physical qubits is that the state can leak outside the computational subspace. To characterize the problem, it is desirable to measure both the leakage probab…
Digital Etching of Single-Crystalline Silicon Fin Barriers Down to Sub-10 nm
Yu Wu, Teun A. J. van Schijndel, Anthony P. McFadden +3
This work presents a fabrication process to realize sub-10 nm-thick, high-aspect-ratio Si fins using high-resistivity float-zone single-crystal Si wafers. Following anisotropic wet…
Magnetic flux distribution, quasiparticle spectroscopy, and quality factors in Nb films for superconducting qubits
Amlan Datta, Bicky S. Moirangthem, Kamal R. Joshi +6
Niobium is a practical material platform for superconducting microwave circuits; however, device-level performance can vary significantly depending on film growth and processing co…
Quasiparticle spectroscopy in tantalum films with different Ta/sapphire interfaces
Bicky S. Moirangthem, Kamal R. Joshi, Anthony P. Mcfadden +8
One of the crucial aspects of current research in quantum information science is the identification and control of loss mechanisms in superconducting circuits. Although microwave m…
