D-Wave Quantum Inc. launched the beta program for its gate-model quantum computing simulator on Oct. 1, 2026, giving four commercial and research organizations early access to a tool designed around its dual-rail superconducting technology — an architecture the company claims can deliver quantum error correction with significantly lower hardware overhead as systems scale.

The Palo Alto, Calif.-based company positions the beta as a milestone on its gate-model development roadmap. Participants will experiment with error-aware programming and build quantum applications ahead of D-Wave's forthcoming gate-model systems, before the simulator reaches general availability. Named beta customers include Spanish bank BBVA, quantum software firm FirstQFM, Florida Atlantic University and the Jülich Supercomputing Centre in Germany.

"Quantum error correction is a defining challenge in the race to commercially useful gate-model quantum computing," said Dr. Alan Baratz, CEO of D-Wave. "By giving leading organizations early access to our simulator, we're enabling them to explore a fundamentally more efficient approach to fault tolerance and the applications we expect it will unlock. The beta program marks a major step in the rapid execution of our roadmap and reinforces D-Wave's leadership in advancing fault-tolerant gate-model quantum computing."

The simulator's underlying dual-rail architecture received recent validation in peer-reviewed research published in Nature. The paper demonstrated a fast, high-fidelity two-qubit entangling gate that preserves the architecture's inherent error-detection advantages — the property D-Wave says lets it detect errors natively rather than paying the heavy qubit overhead that conventional surface-code error correction demands.

Beta customers access the simulator through D-Wave's Leap quantum cloud service and the Ocean software development kit. The company also plans to sell flexible development bundles that combine simulator and future gate-model hardware access with expert guidance, aimed at shortening onboarding for research and development teams.

The early customers span distinct use cases. BBVA, whose quantum lead is Escolástico Sánchez Martínez, will explore financial workloads including portfolio optimization, fraud detection and derivatives valuation. "Quantum computing could open new approaches to some of the financial services industry's most complex computational challenges," Sánchez Martínez said.

FirstQFM CEO Vish Ramakrishnan said his company plans to apply its proprietary foundation models for quantum computing to test whether detected errors, mid-circuit error signals and real-time control can improve the quality and reliability of quantum computations — techniques it intends to port later to dual-rail gate-model hardware. "Error detection creates an opportunity to recover useful information that might otherwise be discarded," Ramakrishnan said.

Florida Atlantic University brings both workforce and research angles. Robert Loredo, executive director of FAU's Center for Quantum Technologies, framed the beta as hands-on preparation for the quantum workforce, while Dr. Arslan Munir, professor of electrical engineering and computer science, said the simulator will let researchers test how error-aware, qubit-efficient approaches affect the robustness of quantum machine learning under realistic hardware constraints — and establish practical design guidelines for future gate-model systems.

At Jülich, Dr. Kristel Michielsen, director of the supercomputing centre, said early access to the "differentiated technology" would let her team contribute insights that could help shape D-Wave's future gate-model systems.

D-Wave describes itself as the world's first commercial supplier of quantum computers and the only vendor offering dual-platform products spanning both annealing and gate-model technologies. Its Leap cloud service, which carries a stated 99.9% availability and uptime figure, serves more than 100 commercial, government and research organizations. The simulator betas signal that the company's gate-model effort is moving from architecture papers toward an operational software stack; whether the dual-rail approach's lower-overhead error correction holds up on real dual-rail hardware will determine how competitive D-Wave becomes against established gate-model players.
