Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
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…
Accelerating Progress Towards Practical Quantum Advantage: The Quantum Technology Demonstration Project Roadmap
Paul Alsing, Phil Battle, Joshua C. Bienfang +32
Quantum information science and technology (QIST) is a critical and emerging technology with the potential for enormous world impact and is currently invested in by over 40 nations…
Implementing two-qubit gates at the quantum speed limit
Joel Howard, Alexander Lidiak, Casey Jameson +8
The speed of elementary quantum gates, particularly two-qubit gates, ultimately sets the limit on the speed at which quantum circuits can operate. In this work, we experimentally d…
Building a Quantum Engineering Undergraduate Program
Abraham Asfaw, Alexandre Blais, Kenneth R. Brown +34
The rapidly growing quantum information science and engineering (QISE) industry will require both quantum-aware and quantum-proficient engineers at the bachelor's level. We provide…
Perspective: Reproducible Coherence Characterization of Superconducting Quantum Devices
Corey Rae H McRae, Gregory M Stiehl, Haozhi Wang +5
As the field of superconducting quantum computing approaches maturity, optimization of single-device performance is proving to be a promising avenue towards large-scale quantum com…
