On May 11, 2026 we reported on the first public S-1 filing that Quantinuum submitted to the U.S. Securities and Exchange Commission (SEC) that provided much detail on the company's technology and operations. Previously, the company announced it had submitted a confidential S-1 in April. In the first public S-1 filing, much of the financial information related to the IPO including valuation, share price, and other important items had not yet been determined and were not included in the document. Now, the company has just submitted an amended S-1A filing that does include this information. We have determined the most significant [...]

Guest Post by Zeynep Koruturk, Dr. Kris Naudts, and Donald Harmitt of Firgun Ventures For years, the headline metric in quantum computing has been a simple one: how many qubits can a company fit onto a single chip. Qubits are the basic units of quantum information, and increasing their number signals that the field is moving beyond laboratory prototypes. The race produced steadily larger processors, but it is widely believed that increasingly fitting a significant number of qubits onto a single chip will eventually run into a wall that physics and manufacturing impose together. Beyond a certain size, fabricating a flawless [...]

MareNostrum-Ona, the quantum computing partition of MareNostrum 5, housed in the Torre Girona chapel at the Barcelona Supercomputing Center. The red and blue systems are the digital quantum computers; the green system in the centre is the newly inaugurated analog quantum computer.Credit: BSC-CNS Qilimanjaro Quantum Tech has officially inaugurated a new analog quantum computer at the Barcelona Supercomputing Center (BSC-CNS). The newly deployed system will integrate directly with BSC’s existing digital quantum infrastructure and the MareNostrum 5 supercomputer. Together, these technologies form MareNostrum-Ona, a unified, hybrid computing environment that stands as one of the most advanced of its kind in Europe. [...]

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. [...]
