Headline: The $100 Million Bet That Could Rewire the Planet
A government writes a check. The ink is still wet. The amount is not small — $100 million for one company, $100 million for another, $2.013 billion spread across nine firms in a single week. The U.S. Department of Commerce signs letters of intent. Commerce Secretary Howard Lutnick calls it “a new era of American innovation.” [3] The stock market responded. Shares of D-Wave Quantum and Rigetti Computing jumped double-digits overnight. Some quantum stocks rose nearly 50 percent in the days that followed.
The next morning, President Emmanuel Macron stands in a supercomputing center south of Paris. He commits another billion euros to France’s own quantum strategy. He drops the diplomatic niceties. He boasts: “We have the means to be the winners of this race.” [4]
Two governments reach for their checkbooks in the same week. Both bet on the same technology. Both frame quantum computing as territory worth defending. The world has seen this before — with semiconductors, with artificial intelligence, with the space race. But quantum computing is different. It does not exist yet in the form that will change everything. It is a promise. A promise that governments now believe is worth $100 million per company, $2 billion per week, and the full weight of national security.
The question is not whether the money is real. The question is whether the technology behind it is ready.
The Old Framework: Grants, Not Stakes
For most of the past decade, governments treated quantum computing the way they treated any laboratory curiosity. They gave grants. They funded national labs. They wrote white papers. They did not take equity stakes.
That changed last month. The U.S. government announced it would take equity stakes in a handful of quantum computing companies. D-Wave Quantum and Rigetti Computing each received up to $100 million in equity investment. The government did not just hand out money. It bought shares. It became a part-owner.
Historically, the U.S. government has taken equity stakes only during periods of severe economic distress. It did so during the 2008 financial crisis. It did so during the COVID-19 pandemic. In each case, the government divested its stake once the companies were healthy again. That was the pattern. That was the expectation.
The Biden administration broke the pattern. It became more proactive with investments. It looked to form partnerships in the interest of national security. It wanted to reduce reliance on foreign competitors. An earlier investment in Intel proved fortuitous — the stock skyrocketed. Now, with quantum computing expected to be the next big technology after artificial intelligence, the U.S. government wants some control over what could become a world-altering technology.
The funding architecture mirrors the CHIPS and Science Act of 2022. Congress passed that act to bring semiconductor manufacturing back to American soil. The government cited national security and supply chain resilience. Its unstated rationale was clear: China is coming for advanced computing, and we are not going to let them have it. Quantum is now getting the same treatment. The two largest checks — $1 billion to IBM and $375 million to another firm — follow the same playbook.
But there is a difference. Semiconductors existed. Quantum computing does not. The government is not investing in a proven industry. It is investing in a set of competing technologies, each with its own strengths, weaknesses, and unanswered questions.
Rigetti: The Speed Problem
Rigetti Computing will receive up to $100 million over three years. The money will support research and development to overcome some of the big technical challenges associated with advancing and scaling superconducting quantum computing. The company’s superconducting technique is fast. It is very fast. But it trails greatly in accuracy when compared to other techniques like trapped-ion.
That is the biggest issue facing the company and its technology. Rigetti had to delay its new 108-qubit Cepheus-1-108Q system to improve its accuracy. When it finally released the system, its 99.1 percent 2-qubit gate fidelity missed the 99.5 percent median 2-qubit gate fidelity it was shooting for at release. The company’s technology also was not chosen to advance to Stage B of the Quantum Benchmarking Initiative for the U.S. Defense Advanced Research Projects Agency. DARPA is a Pentagon-funded program. It helps find and support the best quantum computing technologies. This was a big blow.
Rigetti uses superconducting qubits. These are tiny circuits that conduct electricity without resistance when cooled to near absolute zero. They operate at microwave frequencies. They are fast. They can perform quantum gates in nanoseconds. But they are also fragile. They lose coherence quickly. They accumulate errors. The trade-off between speed and accuracy is the central challenge of superconducting quantum computing.
The company’s approach is traditional. It follows the same path that Google and IBM have taken. It builds chips, cools them, and tries to make them better. The $100 million investment will help, but it does not solve the fundamental problem. Accuracy is not just a milestone. It is the barrier between current quantum computers and useful quantum computers.
D-Wave: The Specialization Problem
D-Wave Quantum will receive a $100 million investment. The money will help accelerate the development of its annealing and gate-model quantum computing technologies. Specifically, it will support a 100,000-qubit annealing system and a 10,000-qubit gate-model system.
D-Wave is a leader in quantum annealing technology. Annealing is a narrower, specialized technology. It shines at solving optimization problems by settling on the best or close to the best answers for complex problems. The technology is further along than broad-based quantum computing. D-Wave already sells machines for commercial use. Industries like finance, logistics, and defense use them.
But annealing is not the big quantum computing riddle companies are trying to solve. The big riddle is gate-based quantum computing. Gate-based systems can run any quantum algorithm. Annealing systems can only run optimization algorithms. That is a fundamental limitation. D-Wave knows this. It is now looking to apply its annealing expertise to traditional gate-based quantum computers.
The company acquired Quantum Circuits. It is now pursuing a dual-rail qubit architecture. It says this architecture will have the fidelity of trapped-ion technology with the speed of superconducting qubits. That is a bold claim. It has not released any technical milestones yet that support this claim.
D-Wave’s strength is its commercial track record. It is the only company that has sold quantum computers for real-world use. Its customers include Mastercard, Volkswagen, and the U.S. Department of Energy. But those customers use the machines for specific optimization problems. They do not use them for general-purpose quantum computing. The gap between what D-Wave sells and what the world expects from quantum computing is still wide.
Quantinuum: The Accuracy Champion
While Rigetti and D-Wave received government investments, another quantum company went public. Quantinuum began trading on the Nasdaq Global Select Market on Thursday under the ticker QNT. It was the largest traditional initial public offering in the history of dedicated quantum computing. The company raised $1.68 billion from the sale of 28 million Class A shares priced at $60 apiece.
Quantinuum was formed in 2021 from the merger of Honeywell Quantum Solutions and Cambridge Quantum. It now carries a public valuation of roughly $14 billion against $30.9 million in 2025 revenue. That is a ratio of more than 450 times. Investors are not buying a current earnings stream. They are buying a bet on a specific technology roadmap and a specific engineering claim: that trapped-ion quantum computers will achieve fault-tolerant performance before any competing architecture does.
The $60 price landed above an already-elevated revised range of $53 to $55 per share. The offering had been upsized twice in the preceding week. The deal was more than 20 times oversubscribed. Allocations favored long-only institutional investors who had engaged directly with Quantinuum management. J.P. Morgan and Morgan Stanley served as joint lead book-running managers. Jefferies, Evercore ISI, BofA Securities, UBS, and a consortium of additional banks also participated.
At the center of Quantinuum’s technical case is the Quantum Charge-Coupled Device, or QCCD, architecture. This design treats trapped barium-137 ions not as static qubits wired to adjacent neighbors, but as mobile quantum information carriers that can be physically shuttled between specialized zones on a microfabricated electrode chip. Storage zones hold idle ions shielded from noise. Processing zones bring pairs of ions together for entangling gate operations. Measurement zones read out results. Any ion can reach any other ion on the chip by moving through this grid. This provides all-to-all qubit connectivity without the complex fixed wiring that constrains competing architectures.
The payoff of this design is fidelity. Helios, Quantinuum’s current commercial system, achieved an average two-qubit gate fidelity of 99.921 percent as of December 31, 2025. That is among the highest confirmed for any commercially deployed quantum system. Fidelity measures how accurately a quantum gate executes its intended operation. At 99.921 percent, roughly one out of every 1,270 gate operations introduces an error. That error rate matters enormously for practical quantum algorithms. Lower error rates allow longer computations before errors accumulate and destroy the result.
Quantinuum’s CEO is Rajeeb Hazra. The company grew out of Honeywell International’s quantum hardware division and the UK-based software firm Cambridge Quantum, which was founded by Ilyas Khan. Khan remains Quantinuum’s largest individual shareholder and chief product officer. Post-IPO, Honeywell retains approximately 49.1 percent of the combined voting power. Public shareholders have meaningful economic exposure but limited governance influence. Cambridge Quantum Holdings holds roughly 32.5 percent of voting rights. Nvidia, Amgen, JPMorgan, and Fidelity participated in the September 2025 private funding round. Their post-IPO positions have not been publicly disclosed.
IonQ: The Other Accuracy Player
Quantinuum is not the only company pursuing trapped-ion technology. IonQ is another. IonQ has achieved 99.99 percent 2-qubit gate fidelity. That is even higher than Quantinuum’s 99.921 percent. Quantinuum has achieved 99.92 percent. Both give them a distinct advantage in accuracy.
IonQ went public earlier than Quantinuum. It trades on the New York Stock Exchange under the ticker IONQ. The company was founded in 2015 by Chris Monroe and Jungsang Kim. Monroe is a professor at Duke University and a pioneer in trapped-ion quantum computing. Kim is a professor at Duke as well. The company has partnerships with Amazon Web Services, Microsoft Azure, and Google Cloud.
IonQ’s approach uses ytterbium ions trapped in a vacuum chamber. Laser pulses perform quantum gates. The system operates at room temperature, unlike superconducting systems that require cryogenic cooling. This is a practical advantage. It reduces the cost and complexity of deploying quantum computers in data centers.
But IonQ faces the same fundamental challenge as every other quantum company. The number of qubits is small. The error rates, while low, are still too high for practical fault-tolerant computation. The company has not yet demonstrated a clear path to scaling beyond a few hundred qubits. The trapped-ion approach is accurate, but it is slow. Gate times are measured in microseconds, not nanoseconds. The trade-off between speed and accuracy remains.
The Government’s Strategy: A Widespread Bet
One notable thing about the investments the government made is that they are spread among companies pursuing quantum computing in very distinct ways. Rigetti is taking a traditional superconducting approach. D-Wave is pursuing a dual-rail qubit architecture based on its leadership in quantum annealing. The government is also investing in Infleqtion, which uses a neutral-atom approach, and Quantinuum, which is pursuing trapped-ion technology.
Overall, the government’s investments look like a widespread bet on different competing quantum technologies. It is not really a bet on individual stocks. As such, I would not necessarily look at it as a validation of the stocks. I would continue to view both D-Wave and Rigetti as highly speculative at this point. I would actually prefer stocks pursuing trapped-ion technology, like IonQ and Quantinuum, given the technology’s accuracy edge.
The government is not picking winners. It is hedging. It is placing small bets on multiple approaches, hoping that one of them pays off. This is a sensible strategy for a government. It is not a sensible strategy for an individual investor. An individual investor cannot afford to bet on every approach. An individual investor must choose.
The Historical Context: From Transistors to Qubits
The current moment in quantum computing resembles the early days of the semiconductor industry. In 1947, John Bardeen, Walter Brattain, and William Shockley invented the transistor at Bell Labs. The device was crude. It could only amplify signals. It could not do much else. Governments and corporations poured money into research. They did not know which approach would win. Bipolar junction transistors competed with field-effect transistors. Silicon competed with germanium. The industry was messy.
By the 1960s, silicon had won. The integrated circuit followed. Moore’s Law was born. The rest is history.
Quantum computing is in a similar phase. Multiple architectures compete. Superconducting qubits, trapped ions, neutral atoms, photonic qubits, topological qubits — each has its advocates. Each has its strengths and weaknesses. None has achieved fault-tolerant quantum computation. None has demonstrated a clear path to scaling beyond a few hundred qubits.
The government’s investments reflect this uncertainty. They are not a vote of confidence in any single technology. They are a vote of confidence in the field as a whole. They are a recognition that quantum computing will matter, even if no one knows exactly which approach will succeed.
The Parallel: CHIPS Act and Quantum
The funding architecture for quantum computing mirrors the CHIPS and Science Act of 2022. That act provided $52.7 billion for semiconductor manufacturing and research. The government cited national security and supply chain resilience. Its unstated rationale was that China is coming for advanced computing, and the United States is not going to let them have it.
Quantum is now getting the same treatment. The two largest checks — $1 billion to IBM and $375 million to another firm — follow the same playbook. The government is not just funding research. It is building infrastructure. It is creating incentives for domestic production. It is reducing reliance on foreign suppliers.
The difference is that semiconductors are a mature industry. Quantum computing is not. The government is investing in a technology that does not yet exist in a practical form. It is betting that the technology will mature before the geopolitical threat does.
The French Reply: A Weight Scale
The French government’s response to the U.S. investments is revealing. President Macron did not just announce funding. He stood in a supercomputing center south of Paris and committed another billion euros to France’s own quantum strategy. He dropped the diplomatic niceties. He boasted: “We have the means to be the winners of this race.”
The French reply is effectively a weight scale. It measures the heft of how seriously the world now takes the American hand. Over the past decade, governments treated quantum the way they would treat any laboratory curiosity — with a grant here, a national lab there. This time, the global response frames quantum as territory worth defending.
France is not alone. The European Union has committed €1 billion to quantum research through its Quantum Flagship program. Germany has committed €2 billion. The United Kingdom has committed £1 billion. China has committed an estimated $15 billion. The global race is on.
The Technical Challenge: Fidelity and Scaling
The central challenge in quantum computing is not building a single qubit. It is building many qubits that work together without errors. This is the problem of fidelity and scaling.
Fidelity measures how accurately a quantum gate executes its intended operation. A 99.9 percent fidelity means that one out of every 1,000 gate operations introduces an error. A 99.99 percent fidelity means that one out of every 10,000 gate operations introduces an error. The difference matters enormously for practical quantum algorithms. Lower error rates allow longer computations before errors accumulate and destroy the result.
Scaling is the other challenge. Current quantum computers have between 50 and 1,000 qubits. Practical quantum algorithms will require millions of qubits. The gap is enormous. No one knows how to bridge it.
Different architectures approach these challenges differently. Superconducting qubits are fast but noisy. Trapped ions are accurate but slow. Neutral atoms are scalable but unproven. Photonic qubits are fast but hard to entangle. Topological qubits are theoretical.
The Investment Verdict: Speculation or Validation?
The question is whether the government’s investment is a validation of quantum computing technology or just a speculative bet. The answer is both.
The government is validating the field. It is saying that quantum computing matters. It is worth investing in. It is worth protecting. That is a signal to the market. It tells investors that the government believes in the technology.
But the government is also speculating. It is betting on multiple approaches. It is hedging its bets. It is not saying that any single company or technology will succeed. It is saying that the field as a whole is worth a bet.
For individual investors, the distinction matters. A widespread bet on the field is not the same as a targeted bet on a specific stock. The government’s investments do not guarantee that D-Wave or Rigetti will succeed. They guarantee that the government wants to be involved in the outcome.
The Sound of the World Changing
The world changes slowly. Then it changes fast. The sound of that change is not a bang. It is a whisper. It is the sound of a check being signed. It is the sound of a government official saying “a new era of American innovation.” It is the sound of a French president boasting that “we have the means to be the winners of this race.”
That sound is not a metaphor. It is an actual sound. It is the sound of paper moving across a desk. It is the sound of a keyboard clicking as a trade is executed. It is the sound of a stock price rising 50 percent in a week.
That sound is. The global race for quantum computing has begun. Governments are investing, companies are competing, and the outcome remains uncertain. The next decade will determine which technologies and nations lead this transformation.
The investments signal a turning point. Quantum computing may still be in its infancy, but the commitment from governments and markets indicates that its impact could be profound. The race is on, and the stakes have never been higher.
