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, [...]

The UK National Quantum Biomedical Research Hub (Q-BIOMED) has been awarded £902,000 ($1.2 million USD) from the Engineering and Physical Sciences Research Council (EPSRC). Delivered through the government's Accelerating Capability Fund—a flexible financial mechanism anchored to the UK's £2.5 billion National Quantum Strategy—the capital injection supports six targeted work packages to develop and translate quantum sensing hardware into clinical medical environments. The initiative establishes new academic partnerships across five research institutions to integrate quantum devices directly into the diagnostics, neuroimaging, and surgical pipelines of the National Health Service (NHS). Technical Architecture & Quantum Hardware Enhancements The six funded work packages target [...]

The University of Tennessee, Knoxville (UT) has launched the Knoxville Quantum Accelerator, branded as K-Quantum, to coordinate regional quantum technology research, hardware validation, and workforce training. The initiative operates in alignment with the Tennessee Quantum Initiative, a $43 million statewide economic strategy directed by Governor Bill Lee to establish localized infrastructure across advanced manufacturing, life sciences, and logistics. By forming public-private research partnerships with regional institutions—including Oak Ridge National Laboratory (ORNL), the Tennessee Valley Authority (TVA), IT consulting firm CGI, and quantum hardware manufacturer IonQ—the accelerator establishes a combined infrastructure pipeline designed to transition foundational quantum mechanics into commercial enterprise tools. [...]

In a sector traditionally dominated by deep-tech milestones and hardware-centric announcements, London-based quantum software startup Moth has broken rank to launch Quantum Backrooms, the world’s first consumer product powered by live quantum hardware. Demonstrating infrastructure agility, Moth confirmed that its consumer applications are platform neutral. Quantum Backrooms was developed to run seamlessly across disparate quantum backends, utilizing hardware from both IBM and IQM during its deployment. The product is currently in the hands of a select group of alpha users and is slated for a wider public launch later this year. Inspired by the popular internet creepypasta and urban legend, Quantum [...]
