Welcome to this week’s quantum update. The biggest investor-facing story is that D-Wave Quantum Inc. (QBTS) is preparing to launch an error-aware gate-model quantum simulator on its Leap cloud platform in September, giving customers a new way to test applications before D-Wave rolls out future gate-model systems.

The sector is still early, and revenue remains limited across much of the industry. Still, the latest news shows steady progress in control systems, U.S. policy planning, public-market preparation, error correction, and developer tools.
Let’s begin.
1. D-Wave Adds Error-Aware Simulator for Developers
D-Wave Quantum Inc. is a quantum computing company known for its annealing systems and its broader push into gate-model quantum computing. The company unveiled a gate-model quantum simulator designed for error-aware programming, with access expected through D-Wave’s Leap cloud platform in September. The simulator will support up to 21 qubits, integrate with D-Wave’s Ocean SDK, and offer ideal and hardware-emulation modes. The key point for investors is that D-Wave is giving developers a tool to model error behavior before its gate-model hardware is broadly available. Dr. Trevor Lanting, D-Wave’s chief development officer, said the simulator is “an important step in bringing our gate-model roadmap to customers.”
2. Quantum Machines Buys PCB Engineering
Quantum Machines is a privately held, Israeli-founded quantum control systems company whose technology helps run and manage quantum processors across multiple hardware types. The company acquired Hungary-based PCB Engineering, creating a new R&D hub in Budapest and marking its second European acquisition in six weeks. The deal expands Quantum Machines’ engineering base as it builds control systems for neutral atoms, superconducting qubits, trapped ions, spin qubits, and other quantum approaches. CEO Itamar Sivan said “quantum computing is almost reaching its turning point,” adding that fault-tolerant quantum computers are getting closer. For investors watching the private quantum supply chain, the acquisition highlights demand for the hardware around the qubit, not just the qubit itself.
3. Lawmakers Push U.S. Quantum Security Commission
Two New York lawmakers introduced the National Security Commission on Quantum Computing Act of 2026, a bill that would create an independent 11-member commission to study U.S. competitiveness in quantum computing. The commission would review national security risks, economic competitiveness, foreign investment, workforce needs, research priorities, and military applications. If passed, it would receive up to $10 million in Department of Defense funding and operate through October 1, 2030. The investment angle is straightforward: Washington is treating quantum as a strategic technology tied to defense, encryption, AI, and long-term economic leadership. That could help keep federal funding and policy support flowing into the sector.
4. IQM Tells Investors It Has Sold 23 Quantum Computers
IQM Quantum Computers is a full-stack superconducting quantum computing company preparing to go public through a planned business combination with Real Asset Acquisition Corp. (RAAQ). IQM held its first Capital Markets Day at the Nasdaq MarketSite in New York, where management presented its strategy, technology roadmap, financial highlights, and commercial progress. The company said it has sold 23 quantum computers to date, more than any other manufacturer. IQM also hosted a panel with representatives from Nvidia Corporation (NVDA), Amazon.com, Inc. (AMZN) Web Services, and Cambium Ventures. If the transaction closes, IQM plans to list on the Nasdaq Global Market under the ticker IQMX.
5. Quantum Art Says Its Architecture Supports Fault Tolerance
Quantum Art is a privately held, Israeli-based quantum computing company developing trapped-ion systems built around a proprietary scale-up architecture. The company reported simulation and noise-modeling results showing that its multi-qubit gate approach can support scalable fault-tolerant quantum computing with finite error-correction thresholds. In plain terms, Quantum Art says errors remain local and controlled as the system scales, which is important for making error correction practical. CTO and co-founder Dr. Amit Ben-Kish said the results show that “multi-qubit gates” are “fully compatible and advantageous for fault-tolerant codes.” The findings support Quantum Art’s roadmap toward its planned 1,000-qubit Perspective platform and later systems designed to host thousands of logical qubits.
