Two-Level Systems in Nucleated and Non-Nucleated Epitaxial alpha-Tantalum films
L. D. Alegria, D. M. Tennant, K. R. Chaves +4
Building usefully coherent superconducting quantum processors depends on reducing losses in their constituent materials. Tantalum, like niobium, has proven utility as the primary s…
Simulating noise on a quantum processor: interactions between a qubit and resonant two-level system bath
Yujin Cho, Dipti Jasrasaria, Keith G. Ray +4
Material defects fundamentally limit the coherence times of superconducting qubits, and manufacturing completely defect-free devices is not yet possible. Therefore, understanding t…
Demonstration of long-range correlations via susceptibility measurements in a one-dimensional superconducting Josephson spin chain
Daniel M. Tennant, Xi Dai, Antonio J. Martinez +20
Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties…
Low frequency correlated charge noise measurements across multiple energy transitions in a tantalum transmon
Daniel M. Tennant, Luis A. Martinez, Kristin M. Beck +5
Transmon qubits fabricated with tantalum metal have been shown to possess energy relaxation times greater than 300 s and, as such, present an attractive platform for high precis…
