D-Wave Quantum Inc. (QBTS) announced a significant research breakthrough in quantum error correction, advancing its path toward practical, fault-tolerant gate-model quantum computing. The research, published in the peer-reviewed journal Nature, demonstrates a new entangling gate that significantly reduces the hardware overhead required to correct quantum errors.
Key Details
- Breakthrough: The company developed a new fast, high-fidelity, two-qubit entangling gate for its superconducting dual-rail qubit architecture.
- Performance: The research demonstrates approximately 99.9% fidelity during two-qubit operations, with fast gate times of about 500 nanoseconds.
- Business Impact: This technology is designed to make scalable error correction more efficient, potentially reducing the logical error rate by a factor of 10 for each error correction increment and lowering the number of physical qubits needed for fault-tolerant systems.
