Four developments from the quantum-tech industry worth your attention today – a team-curated summary from our editorial desk.
D-Wave Transfers Its Stock Listing From the NYSE to Nasdaq
D-Wave Quantum Inc. voluntarily transferred the listing of its common stock from the New York Stock Exchange to Nasdaq, effective after market close on July 24, 2026. Trading under the ticker „QBTS“ began on Nasdaq on July 27, 2026, and CEO Dr. Alan Baratz and the company’s management team rang the Nasdaq Opening Bell to mark the listing debut. D-Wave said it met all Nasdaq listing requirements and expected no disruption to trading activity during the transition.

Qedma Integrates Its QESEM Error-Mitigation Software With Quantinuum’s Hardware
Qedma announced the integration of its Quantum Error Suppression and Error Mitigation (QESEM) software with Quantinuum’s trapped-ion quantum computers, developed over the past year as a founding member of Quantinuum’s Startup Partner Program. QESEM re-engineers standardized algorithms before they run on the hardware to suppress noise at the software level, allowing larger and more complex circuits without added hardware overhead. In initial validation runs on Quantinuum hardware, the software showed measurable fidelity improvements on complex simulations spanning chemistry, materials science and financial modeling.

Researchers Identify First „Zinc Oxide Spin Qubit“ for Room-Temperature Quantum Devices
A team led by Sungkyunkwan University (SKKU), working with the University of Wisconsin–Madison and the University of Washington, identified a molybdenum-oxygen-vacancy defect complex in zinc oxide (ZnO) that functions as a robust, room-temperature spin qubit — the first such qubit found in ZnO, a wide-bandgap semiconductor already integrated into commercial fabrication processes. The defect combines bright visible-light emission, a low Huang-Rhys factor and an estimated spin coherence time of about 4 milliseconds, properties that support efficient quantum-light generation and high-fidelity single-shot spin readout. Because ZnO is compatible with existing crystal-growth and fabrication techniques, the authors suggest the defect could offer a scalable platform for integrated quantum devices if experimentally realized.

Defect-Aware Decoding Sharply Cuts Logical Error Rates on a 120-Qubit Surface Code
A new study implements and compares strategies for running distance-5 surface codes on a square-lattice array of 120 superconducting qubits that, as with any fabrication process, inevitably include some underperforming components. Excluding the defective qubits and couplers from the code, and using a defect-aware decoder that accounts for them during post-processing, produced a dramatic reduction in the probability of a logical error in a memory experiment compared with both a standard approach that ignores defects and simple exclusion alone. The result points to defect-aware software handling, rather than defect-free fabrication, as the near-term path to reliable error-corrected processors.
