Klea Dhmitri of Hamamatsu joins Yuval to discuss the company’s role as a photonic component provider for trapped-ion and neutral-atom quantum computers. She explains key technologies such as photomultiplier tubes (PMTs), SPADs, and quantitative CMOS cameras, and how scaling to larger qubit arrays changes requirements for speed, resolution, and integration. Klea also shares how customer demand is pushing product innovation, reflects on her unconventional path into quantum, and offers advice for those looking to build careers in photonics and quantum technologies. Transcript Yuval: Hello, Klea. Thank you for joining me today. Klea: Hi, Yuval. I’m glad to be here. Yuval: So who are you [...]

By Doug Finke I attended the third convening of a Quantum California event last week at the University of California, San Diego. Two previous convenings were held: one at the University of California, Berkeley in November 2025 and the other at the University of California, Santa Barbara in March of this year. We have been following the quantum scene in California since May of 2016, starting with our article titled Northern versus Southern California – Who’s More Quantum? While some elements of that original article may be out of date, a lot still holds true. It is important to understand that [...]

French President Emmanuel Macron announced an additional funding of €1 Billion ($1.16B USD) for the country's Quantum Plan. The Quantum Plan was original funded at €1.8 billion for the period 2021-2025 and then supplemented in 2024 by €500 million from a program to support public procurement in the defense sector. This new announcement is in addition to those earlier fundings. In his announcement, he noted an acceleration of quantum activity in both the United States and China and indicated a need to have a more proactive European strategy. The announcement also mentioned that France would commit €550 million ($638M USD) to [...]

Xanadu Quantum Technologies (Nasdaq/TSX: XNDU) has established a synthetic at-the-market equity facility allowing the company to raise via private placements up to $300 million over the next three years in Class B subordinate voting shares. Partnering with Yorkville Advisors, this facility gives Xanadu a flexible, opportunistic mechanism to inject capital directly into its treasury for working capital and general corporate purposes to fund its long-term fault-tolerant quantum computing roadmap. Additional information on this can be seen in a press release provided by Xanadu located here. May 22, 2026

Yuval Boger interviews Brian Gaucher, an experienced engineer and IBM veteran who co-chaired ERVA’s report Engineering Research to Advance Quantum Technologies. Brian explains that while U.S. quantum science remains strong, global competition is accelerating and the key limiter is no longer physics discovery but engineering the path from “lab to fab”—scalable, manufacturable, reliable systems. They discuss why the U.S. should pursue a coordinated, semiconductor-like national strategy with shared pilot lines, standards, metrology, public-private investment, and a broader workforce—not just physicists. They also cover the report’s four pillars (materials, biology, computing, AI), the importance of domestic fabrication, and why biology and quantum [...]

We had reported last month that Quantinuum had submitted a confidential S-1 filing with the U.S. Securities and Exchange Commission (SEC). But now, Quantinuum has now updated the filing to publicly release most of the material, with the exception of details related to the proposed number and pricing of the shares and ownership percentages. Quantinuum was formed in 2021 through the merger of Honeywell Quantum Solutions and Cambridge Quantum, the company is a vertically integrated, full-stack quantum computing company. Although the final valuation of the company hasn't been determined yet, it is expected be in the many billions of dollars. While [...]

QuEra Computing Inc. has released Part 2 of its report on the results of its 2026 Quantum Readiness Survey. The survey queried 291 respondents across more than 25 countries on questions covering demographics, perceptions, organizational readiness, technology preferences, and market outlook. The results highlight a "show me" phase where technical progress is benchmarked against real-world budget constraints and geopolitical filters. Market Sentiment: The "Reality Check" Rising Standards for Readiness: While confidence remains high, it has moderated significantly since 2025. Organizations describing their country as "very well positioned" dropped from over 45% to 25%, reflecting a more cautious confrontation with implementation realities. [...]

by Dr. George Schwartz Executive Summary One pervading question in quantum computing has been whether commercially useful quantum advantage can be achieved with early, near-term devices — referred to as the kiloquop era by Global Quantum Intelligence (GQI). Historically, the field has struggled to move beyond esoteric benchmarks to find real-world applications that demonstrate the useful quantum advantage defined by program Q4Bio. However, at GQI, we are observing a tangible transition. Recent notable demonstrations—such as Q-CTRL’s highly optimized 1D Fermi-Hubbard simulation, Algorithmiq’s hybrid tensor-network pipeline for chemical simulation, and Pasqal's modeling of non-equilibrium dynamics in frustrated magnets—provide encouraging evidence for those [...]

Israel-based Quantum Machines (QM) has acquired QHarbor, a spin-off from TU Delft in the Netherlands, to bolster its software capabilities and establish a physical presence in the Dutch quantum hub. The terms of this acquisition were not disclosed. QHarbor is a data storage and visualisation software platform designed for physics researchers and data driven scientists. It provides a secure, structured repository for measurement data, ensuring compliance with data management best practices.  The QHarbor team will form the core of a new R&D office in Delft, focusing on software-defined experimentation and data management. This acquisition marks a significant expansion of QM’s European [...]

eleQtron, a developer of trapped-ion quantum computers based in Siegen and Hamburg, has closed a €57 million ($61.5M USD) Series A funding round. The investment is led by Schwarz Digits, the IT division of the Schwarz Group, with significant participation from the European Innovation Council (EIC) Fund, Earlybird, Ankaa Ventures, Precitec, NRW.BANK, and IFB Innovationsstarter. The round, which ranks among the largest Series A raises in the quantum computing sector globally, is intended to scale the company’s production capacity and expand cloud-based access to its hardware. The MAGIC Technology: Scaling via Microwaves At the core of eleQtron’s hardware is its proprietary [...]
