Diraq has announced the appointment of longtime semiconductor executive Scott A. McGregor as its new Chairman of the Board of Directors. McGregor—former CEO and President of Broadcom and Philips Semiconductors (now NXP), and lead developer of Microsoft Windows 1.0—brings vital CMOS technology scale-up experience to Diraq's silicon-based quantum roadmap. He succeeds the Hon. William Jeffrey, who will remain on the board. The leadership transition coincides with Diraq's accelerating U.S. expansion, supported by a recent Letter of Intent with the U.S. Department of Commerce for up to $38 million in proposed CHIPS Act funding. The full media release can be found here. [...]

Dutch-German hardware developer QuiX Quantum has announced its membership in QuantumBW and Photonics BW, two prominent innovation networks driving technology transfer and industrial scaling within the state of Baden-Württemberg, Germany. The expansion builds directly upon QuiX Quantum’s existing cross-border presence, which includes a dedicated engineering office at the ARENA2036 research campus in Stuttgart and localized operations in Ulm. By embedding its technical capabilities within these regional frameworks, the company aims to link the Netherlands’ established integrated photonics supply chain with southwestern Germany’s specialized high-tech manufacturing base, forming a collaborative corridor to accelerate the industrialization of scalable photonic quantum architectures. Localized Deployment [...]

Cybersecurity and digital identity conglomerate WISeKey International Holding Ltd has finalized the orbital insertion of its WISeSat 4.0 satellite, marking the 21st spacecraft deployed by its space-technology subsidiary, WISeSat.Space Corp. Transported from Vandenberg Space Force Base in California, the payload was launched into low-Earth orbit (LEO) as part of SpaceX’s Transporter-16 rideshare mission. The operation forms part of a systematic infrastructure renewal strategy designed to account for the typical five-year operational lifespan of LEO units, allowing the group to cycle updated hardware configurations into its active satellite network throughout 2026 and 2027. The QS7001 Cryptographic Integration and Space-Based Wallet Topologies The [...]

Cybersecurity and IoT holding entity WISeKey International Holding Ltd has finalized a commercial agreement between its operational subsidiaries, SEALSQ Corp and WISeSat.Space Corp., to co-develop and deploy the Quantum Spatial Orbital Cloud (QSOC). Positioned as a subscription-based managed cloud platform for banking institutions, national defense agencies, and enterprise clients, the QSOC program plans to deploy a 100-satellite low-Earth orbit (LEO) constellation. The space segment will deliver quantum key distribution (QKD), certified quantum random number generation (QRNG), and post-quantum identity frameworks, with incremental hardware deployments scaling toward Full Operational Capability (FOC) by 2033. The Hyperscale Data Center Paradigm: Demarcation of Space and [...]

Post-quantum semiconductor developer SEALSQ Corp and its parent company WISeKey International Holding Ltd have detailed engineering and deployment milestones for their Quantum Spatial Orbital Cloud (QSOC) platform. The space-based infrastructure architecture is designed to configure low-Earth orbit (LEO) satellites as independent, tamper-resistant computing nodes delivering post-quantum cryptography (PQC), certified quantum randomness, and localized edge processing from orbit. The companies confirmed that the initial QSOC-dedicated hardware payload has finalized development and remains on schedule for orbital deployment aboard a SpaceX mission during the fourth quarter of 2026, anchoring a multi-year scaling roadmap aimed at establishing a 100-satellite constellation by 2033. The Converged [...]

United States venture capital firm Alumni Ventures has completed an investment in Yaqumo Inc., a Tokyo-based startup developing neutral-atom quantum computing hardware. Configured as a seed extension financing round, the transaction represents Alumni Ventures’ first capital allocation inside Japan since its institutional founding. The financial placement was co-executed through the firm's North America-focused AV Seed Fund alongside its recently established Japan + US Bridge Fund, an investment vehicle structured to connect the deep-tech startup ecosystems of both nations and facilitate cross-border market expansions. Ytterbium-Based Cold Atom Hardware and Post-Fabrication J-KISS Structuring The capital allocation was formalized utilizing a J-KISS (Keep It [...]

By Doug Finke When I was a junior mainframe computer engineer at IBM, management constantly drilled one core concept into us: RAS: Reliability, Availability, and Serviceability. This principle remains just as vital today as it was back then. The quantum computing landscape is evolving rapidly as these machines transition from laboratory prototypes to commercial production. Quantum systems are growing exponentially more powerful and capable; we are seeing an increase in on-premise installations at remote customer sites, and end users are beginning to rely on quantum computers for mission-critical operations. The Shift from Lab to Enterprise The requirements for a prototype machine [...]

IBM Quantum researchers have introduced ffsim, an open-source Python library engineered for the high-performance classical simulation of quantum circuits that model fermions—the fundamental particles constituting atoms, molecules, and condensed matter. Detailed in a technical preprint deposited on the arXiv repository, the library was developed to supply the quantum information community with faster validation and benchmarking tools as hardware and algorithmic complexities scale. Rather than relying on generic state-vector evolution, ffsim targets specific physical invariants to restrict the active computational workspace, enabling large-scale circuit verifications on standard classical workstations that would otherwise remain inaccessible to general-purpose quantum simulators. Exploiting Physical Symmetries to [...]

Microsoft and trapped-ion hardware developer Quantinuum have published a peer-reviewed paper in the journal Nature detailing physical implementations of quantum error correction (QEC). The paper, titled “Improved quantum processor logical error rates via correction and detection,” presents experimental data collected using Microsoft’s qubit-virtualization platform executed on Quantinuum’s trapped-ion Quantum Charge-Coupled Device (QCCD) hardware architecture. The study documents logical error-rate reductions ranging from 11x to 800x compared to corresponding physical qubit circuit baselines, establishing experimental parameters for error suppression in non-trivial quantum circuits. Dual Code Configurations and QCCD Hardware-Aware Syndrome Extraction The technical framework utilized in the experiments combines two distinct QEC [...]

Swedish DeepTech startup Arkeon Technologies has closed a 6.5 million SEK (€594.2k) ($691K USD) Seed funding round to advance its proprietary post-fabrication precision engineering solutions for the superconducting quantum computing sector. The investment round was backed by a coalition of institutional tech investors, including Chalmers Ventures, Navigare Ventures, and Almi Invest. Founded in 2025 by Peter Hörstedt, Andreas Nylander, and Marcus Rommel, the Gothenburg-based company intends to deploy the capital to accelerate international customer validation, expand its deployment pipeline, and refine its chip-tuning methodologies for commercial foundries.
