Quantum computing hardware for HEP algorithms and sensing

April 19, 2022
Author(s)
Corey Rae McRae
Quantum information science harnesses the principles of quantum mechanics to realize computational algorithms with complexities vastly intractable by current computer platforms. Typical applications range from quantum chemistry to optimization problems and

Perspective: Reproducible coherence characterization of superconducting quantum devices

September 6, 2021
Author(s)
Corey Rae McRae, Joshua Combes, Gregory Stiel, Haozhi Wang, Sheng Xiang Lin, David P. Pappas, Josh Mutus
As the field of superconducting quantum computing approaches maturity, optimization of single-device performance is proving to be a promising avenue toward large-scale quantum computers. However, this optimization is possible only if performance metrics

Cryogenic single-port calibration for superconducting microwave resonator measurements

June 28, 2021
Author(s)
Haozhi Wang, Suren Singh, Corey Rae McRae, Joseph C. Bardin, S.-X. Lin, A. R. Castelli, Y. J. Rosen, David P. Pappas, J. Y. Mutus
Superconducting circuit testing and materials loss characterization requires robust and reliable methods for the extraction of internal and coupling quality factors of microwave resonators. A common method, imposed by limitations on the device design or

Cryogenic microwave loss in epitaxial Al/GaAs/Al trilayers for superconducting circuits

January 14, 2021
Author(s)
Corey Rae McRae, A. McFadden, Ruichen Zhao, Haozhi Wang, Junling Long, Tongyu Zhao, Sungoh Park, Mustafa Bal, Christopher J. Palmstrom, David P. Pappas
Epitaxially grown superconductor/dielectric/superconductor trilayers have the potential to form high-performance superconducting quantum devices and may even allow scalable superconducting quantum computing with low-surface-area qubits such as the merged

Materials loss measurements using superconducting microwave resonators

June 9, 2020
Author(s)
Corey Rae H. McRae, Haozhi Wang, Jiansong Gao, Michael R. Vissers, Teresa Brecht, A Dunsworth, David P. Pappas, J. Mutus
The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two-level system (TLS) losses at single photon powers and millikelvin temperatures. The identification

Overlap junctions for superconducting quantum electronics and amplifiers

May 25, 2020
Author(s)
Mustafa Bal, Junling Long, Ruichen Zhao, Haozhi Wang, Sungoh Park, Corey Rae H. McRae, Tongyu Zhao, Russell Lake, Daniil Frolov, Roman Pilipenko, Silvia Zorzetti, Alexander Romanenko, David P. Pappas
Due to their unique properties as lossless, nonlinear circuit elements, Josephson junctions lie at the heart of superconducting quantum information processing. Previously, we demonstrated a two-layer, submicrometer-scale overlap junction fabrication

Dielectric loss extraction for superconducting microwave resonators

May 5, 2020
Author(s)
Corey Rae H. McRae, Russell Lake, Junling Long, Mustafa Bal, Xian Wu, Battogtokh Jugdersuren, Thomas Metcalf, Xiao Liu, David P. Pappas
The investigation of two-level-state (TLS) loss in dielectric materials and interfaces remains at the forefront of materials research in superconducting quantum circuits. We demonstrate a method of TLS loss extraction of a thin film dielectric by measuring

Enhanced superconducting transition temperature in electroplated rhenium

April 30, 2018
Author(s)
David P. Pappas, Don David, Mustafa Bal, Ilke Arslan, Paul T. Blanchard, Ronald B. Goldfarb, Dustin A. Hite, Hsiang S. Ku, Russell E. Lake, Junling Long, Alexana Roshko, Lee D. Pappas, Britton L. Plourde, Jianguo Wen, Xian Wu, Corey Rae H. McRae
We show that electroplated Re films in multilayers with noble metals such as Cu, Au, and Pd have an enhanced superconducting critical temperature relative to previous methods of preparing Re. The dc resistance and magnetic susceptibility indicate a critical
