Suppressing Counter-Rotating Errors for Fast Single-Qubit Gates with Fluxonium

1 min read

Demonstrates few-cycle, high-fidelity fluxonium control using circularly polarized and commensurate pulses to suppress counter-rotating errors beyond the rotating-wave approximation.

Key Results

  • Best measured average single-qubit gate fidelity: .
  • Optimized commensurate pulse duration: approximately .
  • The best gates were coherence limited and remained stable over 34 hours after calibration.
