Forschungszentrum Jülich Demonstrates 6.8-Nanosecond Single-Qubit Gates with > 99.98% Fidelity via Multi-Photon Leakage Suppression
TL;DRGerman researchers achieved ultra-fast, ultra-accurate quantum gates using new pulse-shaping technique.
Why it matters: Near-perfect fidelity at high speeds moves practical quantum computers closer to viability.
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…
