AlphaCNOT uses model-based RL with tree search to reduce CNOT gate counts in quantum circuits by up to 32% versus classical methods.

  • CNOT gates dominate error propagation in noisy quantum devices; minimizing them improves reliability.
  • AlphaCNOT frames gate minimization as a planning problem, enabling lookahead evaluation of gate sequences.
  • Model-based RL with MCTS outperforms model-free RL by exploring future trajectories before committing to actions.
  • Achieves 32% reduction over Patel-Markov-Hayes baseline on linear reversible synthesis without topology constraints.
  • Handles topology-aware synthesis where CNOT gates operate only on specific qubit pairs.
  • Scales to 8-qubit systems with consistent improvements over prior RL approaches.
  • Framework generalizes to other circuit optimization tasks like Clifford gate minimization.

  • A CNOT (Controlled-NOT) is a two-qubit quantum gate fundamental to universal quantum computation. Current quantum devices are noisy; each gate introduces errors that accumulate. Minimizing CNOT count reduces total error propagation, improving circuit reliability and success rates on real hardware.
