D-Wave Quantum Inc. (NYSE: QBTS) rose in Thursday's premarket trading, gaining 3.62% to $23.75, as investors reacted to the launch of a new quantum simulator and broader market strength. The move extends recent gains fueled by a proposed $100 million CHIPS Act award and analyst optimism, though the stock remains below recent highs.

Gate-Model Simulator Launch

D-Wave introduced what it calls the world's first gate-model quantum computing simulator designed for error-aware programming. Built on dual-rail technology, the simulator allows developers to model processor behavior, detect errors, and test correction workflows. It is scheduled to launch on the Leap cloud platform in September 2026, supporting up to 21 qubits and integration with the Ocean software development kit. The company also introduced Starter and Premium quantum development bundles with pricing available upon request.

Analyst Support and CHIPS Act Funding

Mizuho Securities maintained an Outperform rating and raised its price forecast to $35 from $29 on June 15. Other firms have also increased targets, with B. Riley Securities raising its forecast to $40 and Rosenblatt maintaining a Buy rating with a $43 target. The consensus price forecast stands at $39.56. Optimism also persists after the U.S. Department of Commerce issued a non-binding letter of intent proposing up to $100 million in funding under the CHIPS and Science Act to support system development.

Technical Levels and Earnings Outlook

D-Wave is trading 8.8% below its 20-day simple moving average (SMA) of $26.02 but holds 6.5% above its 50-day SMA of $22.28. The stock faces resistance near $25.00, with support at $22.50. The relative strength index (RSI) is at 47.25, indicating consolidation. The company is expected to report earnings on Aug. 6, with Wall Street projecting a loss of 10 cents per share on revenue of $4.04 million.

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.
