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…
Cryogenic growth of aluminum: structural morphology, optical properties, superconductivity and microwave dielectric loss
Wilson J. Yánez-Parreño, Teun A. J. van Schijndel, Anthony P. McFadden +7
We explore the molecular beam epitaxy synthesis of superconducting aluminum thin films grown on c-plane sapphire substrates at cryogenic temperatures of 6 K and compare their behav…
Cryogenic growth of tantalum thin films for low-loss superconducting circuits
Teun A. J. van Schijndel, Anthony P. McFadden, Aaron N. Engel +5
Motivated by recent advancements highlighting Ta as a promising material in low-loss superconducting circuits and showing long coherence times in superconducting qubits, we have ex…
Frequency-Tunable Josephson Junction Resonator for Quantum Computing
K. D. Osborn, J. A. Strong, A. J. Sirois +1
We have fabricated and measured a high-Q Josephson junction resonator with a tunable resonance frequency. A dc magnetic flux allows the resonance frequency to be changed by over 10…
