Advancing Quantum Error Correction With Dual-Rail Technology D-Wave's peer-reviewed Nature paper demonstrates a fast, high-fidelity two-qubit entangling gate that preserves the error-correction advantages of its superconducting dual-rail qubit architecture. This breakthrough advances the path to practical, fault-tolerant quantum computing. Removing a Barrier to Fault-Tolerant Quantum Computing Error correction is one of the industry’s most consequential challenges on the path to scaled fault-tolerant gate-model quantum computing. The benefits of quantum error correction typically come with high overhead in the number of physical qubits, creating substantial engineering complexity, cost and performance constraints. D-Wave's Nature paper, “An entangling gate for dual-rail erasure qubits,” details a new two-qubit entangling gate, a fundamental building block of quantum computation, designed to support efficient quantum error correction. The research demonstrates approximately 99.9% fidelity during two-qubit operations, with fast gate times of about 500 nanoseconds, enabled by native hardware-level error detection. The results establish an important foundation for scalable quantum error correction, validating that D-Wave's superconducting dual-rail architecture can reduce the quantum and classical hardware overhead typically required to detect and correct quantum errors while maintaining fast, high-fidelity operations. D-Wave's dual-rail qubits are superconducting quantum devices that create, store, and manipulate quantum information to perform computations. Unlike other quantum computing architectures, the dual-rail qubit is designed to detect errors at the hardware level. Click here to see the full annotated graphic. A Two-Qubit Gate Designed for Quantum Error Correction D-Wave's dual-rail architecture is designed to create a favorable error hierarchy in which the most common quantum errors are also the easiest to correct. The newly published research demonstrates that this favorable error hierarchy is preserved during two-qubit operations, with the technology maintaining both speed and high fidelity. The results establish an important foundation for scalable quantum error correction with substantially lower hardware overhead. Leveraging these results, D-Wave simulations
