D-Wave Quantum Inc. announced a forthcoming gate-model quantum computing simulator designed for error-aware programming, enabling developers to prototype applications and model quantum processor behavior. The simulator, expected to be the first of its kind, is scheduled for availability in September 2026 on D-Wave's Leap cloud platform. This development marks the next step in D-Wave's gate-model roadmap, following its recent outline of a differentiated approach to fault-tolerant quantum computing.

The simulator is built around D-Wave's dual-rail technology, which integrates error detection and real-time control into the architecture. This design provides developers with visibility into errors, allowing them to design applications and workflows that respond to real processor behavior. The toolkit will include support for up to 21 qubits, ideal and hardware emulation modes, and Monte Carlo simulation of real-time quantum system dynamics. It also integrates with D-Wave's Ocean SDK and other familiar development tools.

D-Wave will offer quantum development bundles to provide access to the simulator and systems. These bundles, available as Starter and Premium packages, include monthly access allocations and guidance from D-Wave's team of experts. The offerings are designed to streamline onboarding, support flexible research and development, and maximize customer value. Pricing for the bundles is available upon request.

Key Features of the Simulator

Dr. Trevor Lanting, chief development officer at D-Wave, emphasized the importance of error awareness in the architecture. He stated that the simulator is intended to help customers build expertise in advance of the company's forthcoming gate-model quantum systems. Customers can sign up to request future access to the simulator and systems.
