Description

Niril George and co-authors find in 2025 the fastest safe control pulses for a two-qubit gate in superconducting quantum computers. Fast gates fight decoherence, the noise that erodes quantum states, but real devices carry parameter errors that standard designs ignore. Their robust control method shapes pulses that stay accurate despite such errors. A cross-resonance gate ran in sixty-four nanoseconds with very high fidelity under ten percent parameter error.

Stretching to seventy-one nanoseconds traded a little speed for similar quality under smaller error. At one hundred nanoseconds, pulses also shrugged off time-varying noise far above typical levels. The work maps the true speed limits for this hardware.
