Forschungszentrum Jülich Demonstrates 6.8-Nanosecond Single-Qubit Gates with > 99.98% Fidelity via Multi-Photon Leakage Suppression

Physicists at Forschungszentrum Jülich, RWTH Aachen University, and the University of Cologne have achieved record-breaking 6.8-nanosecond single-qubit gate operations with over 99.98% fidelity on a superconducting transmon processor. Their "R2D" pulse-shaping method effectively suppresses multi-photon leakage, allowing for ultrafast gates while maintaining high fidelity. This advancement, detailed in Nature Communications, marks a significant step in quantum computing, though scaling to multi-q
