Overview

Control strategy demonstrates CZ gates under 100ns in fluxonium architectures, suggesting scalability for quantum processors.

Key Points

  • Fast entangling gates using parametric modulation achieve error rates below 0.0001.
  • A bSWAP-type interaction enables rapid excitation and de-excitation of coupled fluxonium plasmon modes.
  • Utilizing a tunable coupler allows for controlled-phase gate realization in scalable architectures.
  • The approach may provide a foundational framework for developing robust quantum processors.
