Quantum gates set speed record at 6.8 nanoseconds with over 99.98% accuracy

AI Summary

Researchers from Jülich, Aachen, and Cologne performed a quantum operation on a qubit in 6.8 nanoseconds with more than 99.98% accuracy, setting a speed benchmark. The findings, published in Nature Communications, could advance quantum computing by making superconducting-qubit operations faster.

Researchers from Jülich, Aachen and Cologne have performed a quantum operation on a qubit in just 6.8 nanoseconds—with more than 99.98% accuracy. Such operations typically take several tens of nanoseconds in superconducting quantum computers. The paper was published in Nature Communications.
