TLS Dynamics in a Superconducting Qubit Due to Background Ionizing Radiation
Ted Thorbeck, Andrew Eddins, Isaac Lauer +2
Superconducting qubit lifetimes must be both long and stable to provide an adequate foundation for quantum computing. This stability is imperiled by two-level systems (TLSs), curre…
High-fidelity superconducting quantum processors via laser-annealing of transmon qubits
Eric J. Zhang, Srikanth Srinivasan, Neereja Sundaresan +19
Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key challenge for quantum computing. Presently, superconducting quantum processors with >50-qub…
Demonstration of quantum volume 64 on a superconducting quantum computing system
Petar Jurcevic, Ali Javadi-Abhari, Lev S. Bishop +28
We improve the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume, with a combination of dynamical decoupling, compiler opt…
Challenges and Opportunities of Near-Term Quantum Computing Systems
A. D. Corcoles, A. Kandala, A. Javadi-Abhari +6
The concept of quantum computing has inspired a whole new generation of scientists, including physicists, engineers, and computer scientists, to fundamentally change the landscape…
Verifying Multipartite Entangled GHZ States via Multiple Quantum Coherences
Ken X. Wei, Isaac Lauer, Srikanth Srinivasan +6
The ability to generate and verify multipartite entanglement is an important benchmark for near-term quantum devices devices. We develop a scalable entanglement metric based on mul…
Analytical determination of participation in superconducting coplanar architectures
Conal E. Murray, Jay M. Gambetta, Douglas T. McClure +1
Superconducting qubits are sensitive to a variety of loss mechanisms which include dielectric loss from interfaces. The calculation of participation near the key interfaces of plan…
