Adaptive Leakage Detection for Quantum Error Correction

156 words·1 min

Leaked qubits silently corrupt syndrome extraction and poison decoding in quantum error-correcting codes. This project designs leakage speculation strategies that precisely detect and mitigate leakage errors across QEC codes, plus an adaptive strategy that reduces how long leakage lingers in the code.

Key results
#

  • 16% improvement in logical error rate from speculation-aware decoding.
  • 2–3× reduction in leakage accumulation via adaptive strategies across various QECCs, reducing QEC cycle time.
  • Ongoing follow-up: an efficient ML decoder for the surface code that incorporates leakage speculation and uses adaptive RL to track evolving error profiles.
