D-Wave Demonstrates Entangling Gate for Dual-Rail Qubits

D-Wave, with collaborators, reports successfully testing an entangling gate on its dual-rail qubits, a design that encodes quantum information differently from standard superconducting qubits. The work, published in Nature, validates a key component needed for dual-rail erasure qubits, which offer a promising path toward more efficient quantum error correction. This marks an important step in making this qubit architecture a viable contender for large-scale quantum computing.
