The White House held a quantum innovation summit on Tuesday that drew well over 100 attendees in a standing-room-only event, signaling serious federal commitment to a technology that could reshape everything from national security to cryptocurrency markets. The summit reflects a burst of government activity: the Department of Commerce announced more than $2 billion in incentives for nine quantum-focused companies two months ago, and President Donald Trump signed two executive orders days ago aimed at boosting quantum development and preparing federal systems for quantum-enabled cyberattacks.
This isn't idle investment. The government is backing its spending with actual assessment mechanisms. The Defense Advanced Research Projects Agency's Quantum Benchmarking Initiative, or QBI, is determining whether the U.S. can build an industrially useful quantum computer by 2033. The initiative examines the feasibility of creating "utility-scale, fault-tolerant quantum computers" — machines that are cost-effective and can operate despite computational and hardware imperfections. A DARPA spokesperson stated, "QBI's goal is to provide the U.S. government with the best possible assessment of the current state of commercial quantum computing and its likely trajectory, so that those stakeholders can make informed decisions."
What's striking is the intellectual honesty built into the process. Joe Altepeter, the founding program manager of QBI, said during a December conference that the agency is fully prepared to accept that developing an industrially useful quantum computer won't be possible in the next seven years. "Our job is to prevent surprise and give ground truth to the U.S. government to make wise decisions," he told the crowd. "And we are perfectly fine if the answer is: 'No one's going to be able to build this. We should spend our money building giant robots or curing cancer instead — don't worry about quantum computing.'" That's the kind of disciplined thinking that should govern federal spending.
The Crypto Vulnerability
Meanwhile, the cryptocurrency industry is confronting an existential threat that no amount of decentralized idealism can solve. Quantum computers can solve complex mathematical problems much faster than today's sophisticated computers and could unscramble the conventional cryptography that protects the $2 trillion global cryptocurrency market. The threat isn't theoretical anymore. Google research from March suggested quantum computers may be able to break that cryptography by 2029, whereas they were previously seen as at least a decade away. Citigroup and other researchers have concluded that quantum computing, along with artificial intelligence breakthroughs, has compressed the timeline in which cryptocurrencies become vulnerable.
The problem runs deep. Most blockchains rely on decades-old elliptic-curve cryptography to generate public and private keys and digital signatures used to verify ownership of crypto assets. While conventional computers cannot feasibly derive a private key from a public key, a sufficiently powerful quantum computer could do so, allowing hackers to forge digital signatures and authorize fraudulent transactions. Bitcoin, the largest cryptocurrency, is considered particularly vulnerable because its 17-year history has generated a large number of visible public keys. An unpublished June 2026 working paper by independent researcher Ahmed Raza Muhammad Umer estimates roughly 35% of Bitcoin's circulating supply could be exposed to a quantum computing attack. Other research estimates that figure could reach 50%.
The market implications are severe. Cristiano Ventricelli, vice president and senior analyst of digital assets at Moody's Ratings, said just one incident in which a hacker steals and sells a large amount of a token could tank its price. "Everyone will feel the impact," he added. Christopher Wood, the closely tracked global head of equity strategy at Jefferies, removed a 10% bitcoin allocation from his model portfolio in his January newsletter because of the long-term "existential" threat of quantum computing.
The Infrastructure Challenge
Crypto companies are already drawing up plans to upgrade their networks with quantum-resistant cryptography. Chris Tam, head of quantum innovation at BTQ Technologies, called it "the most direct and existential threat towards cryptocurrencies and crypto networks." But the engineering challenge is immense. Post-quantum digital signatures are generally much larger than traditional signatures, increasing storage and bandwidth requirements and potentially raising costs and degrading user experience. Zach Pandl, head of research at crypto asset manager Grayscale, noted, "There is an engineering challenge ahead, but there are engineering solutions already on the table."
One senior cybersecurity executive at a major crypto player expects it will take two years for his company to become fully quantum-resistant. The effort has been compared to a Y2K-style overhaul, when more than $300 billion was spent globally fixing the "millennium bug." The problem is especially thorny for blockchains, which are mostly decentralized, meaning they're operated by communities that may not be able to agree on a path forward.
None of the top 20 blockchains have implemented a post-quantum signature algorithm. In Bitcoin's case, developers and market participants are divided over which fix to adopt and when to move. The Ethereum Foundation, which supports the blockchain underpinning ether, the second-largest cryptocurrency, says it's targeting 2029 for full protection. Christopher Smith, CEO of Quantus, a blockchain that already uses post-quantum cryptography, warned, "The sort of disaster scenario is that it happens way sooner than we think."
The Algorand Foundation, which supports the Algorand blockchain with a market capitalization around $780 million, is among the early movers. It published a post-quantum roadmap a month ago and plans to start supporting post-quantum accounts later this year. Bruno Martins, Algorand Foundation's chief technology officer, said, "It felt right to start doing something now, because it's responsible to have a plan."
European Innovation and Manufacturing Speed
While America focuses on quantum development and defense, Europe is moving aggressively on the manufacturing side. QuantumDiamonds, a German startup applying a novel approach to inspecting chips, received €76 million in non-dilutive funding with European Commission approval, provided by Germany's federal economy ministry and the state of Bavaria. The startup also raised a €15 million equity round led by VC firm World Fund, backed by Bayern Kapital and existing investors including Creator Fund, Earlybird, First Momentum, IQ Capital, Onsight Ventures and UnternehmerTUM.
QuantumDiamonds is a spinout from the Technical University of Munich and represents the kind of deep-tech commercialization that Europe's funding ecosystem is designed to support. The company compresses a defect detection process that usually takes weeks into a two-minute inspection that doesn't stop production lines. CEO Kevin Berghoff said it can help major foundries and memory makers save hundreds of millions of dollars, with hardware typically paid back entirely within a couple of months. The startup also charges subscription fees for on-site support and software that interprets data.
Berghoff explained that QuantumDiamonds uses synthetic diamonds and their tiniest properties to observe how electricity flows through chips. Compared with current inspections that look at the top layer of a chip with a microscope, this approach detects defects through all layers without destroying the chip. The capability is particularly relevant as chips become increasingly multi-layered. "The transistors cannot get smaller, so in order to get the same power and the same compute, you start to add more and more layers," he said.
Large competitors, including "100 billion market-capped U.S.-based inspection companies," will likely adapt at some point, but QuantumDiamonds has first-mover advantage. "There is no U.S. or Asian company that has shipped those tools," Berghoff noted. The startup is moving from client labs to semiconductor manufacturing plants, or fabs. Lab tools cost single-digit millions, while high-throughput systems could reach $10 million to $15 million—far below ASML machines that cost around $400 million.
Daria Saharova, World Fund managing partner, wrote that QuantumDiamonds "can become Europe's next ASML." The new funding will generate jobs in Munich, where most of the company's 70-person team is based. Berghoff and co-founder Fleming Bruckmaier plan to double the engineering team over the next 12 months, leveraging affordable talent with both quantum and semiconductor expertise. QuantumDiamonds has already opened a regional hub in Taiwan and completed first commercial deployments in Taiwan and the U.S., installing a system at Eurofins EAG Laboratories in Sunnyvale, California.
Why This Matters:
The quantum computing race reveals three critical governance challenges. First, the federal government is appropriately using structured assessment—DARPA's Quantum Benchmarking Initiative—to avoid throwing money at hype. The willingness to accept that 2033 goals may be unachievable shows disciplined fiscal stewardship. Second, the cryptocurrency vulnerability exposes the limits of decentralized systems when facing existential infrastructure challenges; the inability of blockchain communities to coordinate upgrades demonstrates why property rights and clear governance matter. Third, Europe's aggressive funding of manufacturing innovation through non-dilutive capital shows how targeted, outcome-focused investment can build competitive advantage without government picking winners. The U.S. is investing in quantum development; Europe is investing in the tools to manufacture quantum-era chips. Both approaches matter, but they reveal different philosophies about government's role—assessment and defense versus direct commercialization support.
