D-Wave publishes Nature paper on dual-rail qubit gate with 99.9% fidelity, advancing fault-tolerant quantum computing
--------------------------------------------------------------------------------

- Paper in Nature demonstrates two-qubit entangling gate with ~99.9% fidelity and ~500 ns gate times.
- Dual-rail architecture enables native error detection; simulations show logical error rate reduction by factor of 10 per error-correction increment.
- Supports D-Wave's roadmap to 100-logical-qubit fault-tolerant system by 2032.
- CEO Alan Baratz says breakthrough confirms path to commercial fault-tolerant quantum computing.
