Item 7.01 Regulation FD Disclosure.
On August 5, 2026, D-Wave Quantum Inc. (“D-Wave”) announced a major research breakthrough advancing the path to practical, fault-tolerant gate-model quantum computing. Published in the peer-reviewed scientific journal Nature, the research demonstrates a fast, high-fidelity, two-qubit entangling gate that preserves the error-correction advantages of D-Wave’s superconducting dual-rail qubit architecture. The results address one of the industry’s most consequential challenges by reducing the immense quantum and classical hardware overhead typically required to detect and correct quantum errors as systems scale.
The 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. Leveraging these results, D-Wave simulations indicate its dual-rail architecture could reduce the logical error rate by as much as a factor of 10 for each increment in error correction, significantly reducing the physical qubit overhead required for fault-tolerant quantum computing.
According to D-Wave’s CEO, Dr. Alan Baratz, this research demonstrates that D-Wave’s dual-rail architecture combines fast superconducting operations with high-fidelity performance while preserving native hardware-level error detection. D-Wave believes this work confirms that its path to commercial fault-tolerant quantum computing is practical and achievable. A copy of the press release is attached as Exhibit 99.1.
