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…
Ultrahigh Vacuum Packaging and Surface Cleaning for Quantum Devices
M. Mergenthaler, S. Paredes, P. Müller +7
We describe design, implementation and performance of an ultra-high vacuum (UHV) package for superconducting qubit chips or other surface sensitive quantum devices. The UHV loading…
Laser-annealing Josephson junctions for yielding scaled-up superconducting quantum processors
Jared B. Hertzberg, Eric J. Zhang, Sami Rosenblatt +8
As superconducting quantum circuits scale to larger sizes, the problem of frequency crowding proves a formidable task. Here we present a solution for this problem in fixed-frequenc…
Suppression of Unwanted Interactions in a Hybrid Two-Qubit System
Jaseung Ku, Xuexin Xu, Markus Brink +4
Mitigating crosstalk errors, whether classical or quantum mechanical, is critically important for achieving high-fidelity entangling gates in multi-qubit circuits. For weakly anhar…
