Delft-based cybersecurity firm QuDef has announced the commercial availability of SQOUT®, a dedicated quantum threat intelligence and security assessment software platform. Developed to secure Quantum Key Distribution (QKD) and post-quantum network layers, the tool provides chief information security officers (CISOs), risk managers, and red/blue security teams with an environment to model, assess, and mitigate hardware and protocol-specific vulnerabilities. The platform addresses implementation gaps emerging as quantum communication networks transition from isolated laboratories into operational aerospace, defense, and national critical infrastructure systems. Technical Architecture & Vulnerability Analysis While QKD methodologies—including BB84, BBM92, Continuous-Variable (CV-QKD), and Measurement-Device-Independent (MDI-QKD) protocols—maintain mathematical proofs of security [...]

Espoo-based hardware developer IQM Finland Oy and special purpose acquisition company Real Asset Acquisition Corp. (Nasdaq: RAAQ) have reopened and upsized their Private Investment in Public Equity (PIPE) allocation to $146 million. The capital expansion is driven by a new institutional investment from Ilmarinen, one of Finland’s largest private earnings-related pension insurance companies, supplementing the previously secured $134 million anchor PIPE pool. The transaction maintains a pre-money equity valuation of $1.8 billion for the full-stack superconducting developer as it prepares to complete its reverse-triangular merger. Technical Architecture & Vertically Integrated Production Models The expanded financing loop funds IQM's physical hardware scaling [...]

Enschede-based hardware developer QuiX Quantum has announced the initial installation of its Feed-Forward Control Unit (FFCU). Integrated directly into the company’s universal photonic quantum computing stack, the high-performance module is engineered to handle real-time adaptive operations. By automating state reconfiguration at the hardware level, the control mechanism establishes the fast feedback loops required for measurement-based quantum computing architectures. Technical Architecture & Nanosecond Feed-Forward Latency The FFCU addresses the operational constraints of measurement-based photonic frameworks, where calculations are executed via a continuous sequence of single-photon detections. Because information is encoded in single photons propagating through optical paths at the speed of light, [...]

At their annual Build Conference, Microsoft announced improvements in its Majorana qubit design that provides a 20 second parity lifetime with a 1000x increase in the switching time in Majorana parity measurements. This design has been incorporated into their next generation chip called Majorana 2. A key parameter in a Majorana based qubit is called the topological gap and the changes they have made increased this by a factor greater than 2X over their previous design. They have accomplished this by designing an improved material stack incorporating lead (Pb) as the superconductor instead of the previous aluminum, antimony (Sb), and fabricated [...]

This week, Yuval Bogar interviews Sebastian Hassinger, host of The New Quantum Era podcast, and author of a new book by the same name. Sebastian and Yuval have many things in common beyond their jobs in quantum. They are both podcasters, neither of them has a PhD, and they are both authors of new books – Sebastian’s The New Quantum Era, and Yuval's Quantum Bits, the Comic Book Guide to Quantum Computing. In a conversation that is more symmetric than the typical episode, they compare notes about the motivation and process of writing these books, explaining quantum computing for non-physicists, debate [...]

D-Wave Quantum Inc. (NYSE: QBTS) has unveiled a gate-model development roadmap aimed at the production of commercial, fault-tolerant quantum computing systems. Announced at the firm's inaugural Investor Day at the New York Stock Exchange, the strategic plan outlines a trajectory to deliver a 100-logical-qubit system capable of executing over one million operations by 2032. This long-term system architecture incorporates the asset portfolio of recent acquisition Quantum Circuits, Inc., combining D-Wave's existing cryogenic infrastructure with a specialized superconducting dual-rail qubit design and integrated quantum error correction (QEC). Technical Architecture & Dual-Rail Qubit Error Detection The technical roadmap focuses on hardware-level error reduction [...]

Quandela has announced a major restructuring of its executive leadership and governance to drive the international scale-up of its photonic quantum computing hardware. Cyril Dujardin, an executive with 25 years of deep tech and cybersecurity experience at Atos and Eutelsat/OneWeb, has been named Chief Operating Officer (COO). Joining him is semiconductor and aerospace operations veteran Michel Zecri as VP of Industrialization, who will lead the manufacturing and supply chain maturity of Quandela's hardware platforms. Additionally, board member and former CEO of OVHcloud Michel Paulin has been elevated to Chairman of the Board. The full announcement can be found here. Zapata Quantum [...]

Pramatra Space Technology Pvt. Ltd., a deep-tech quantum security venture based in Bengaluru, has closed an undisclosed pre-seed financing round led by Seafund Ventures. The investment round included participation from Rebalance, Magnivia Ventures (co-investing with the Peaceful Progress Fund), and angel investors including Awais Ahmed, founder of earth observation company Pixxel Space. This financing supplements capital from early backers including Techstars, Roh Ventures, Almagest Space, and KRISS Portfolio. The capital injection is designated to fund hardware development, focusing on flight-qualification protocols for the company's proprietary components. Technical Architecture & Integrated Photonics QKD Substrate The technical roadmap managed by Pramatra Space addresses [...]

An electromagnetic wave packet propagating (a) in free space, (b) from free space to a sharp jump in plasma density (which mimics the edge of a confined overdense plasma), and (c) through an inhomogeneous plasma with a spatially varying density profile. Rigetti Computing, in collaboration with Lawrence Livermore National Laboratory and the University of Colorado, Boulder, has executed a noiseless surrogate "spin" model simulation tracking linear plasma wave propagation and scattering profiles. Published in Physical Review Applied, the research was conducted using a nine-qubit cluster on Rigetti's 84-qubit Ankaa-3 superconducting quantum computer. By employing dual error mitigation routines to suppress phase [...]

Quantum Machines (QM) has operated Rigetti Computing’s commercially available Novera superconducting quantum processing unit (QPU) using external control hardware and software, reaching a 99.5% median two-qubit gate fidelity. Configured via the OPX1000 orchestration platform and managed by QUAlibrate automation software, the onsite optimization process achieved full calibration within ten days. The results match the peak internal calibration metrics recorded by the hardware manufacturer, validating that high-performance superconducting processors can maintain stable execution parameters when decoupled from the developer's proprietary control infrastructure. Technical Architecture & Device Tuning Specifications The Novera processor is an on-premises 9-qubit superconducting QPU engineered on Rigetti’s Ankaa-class architecture, [...]
