One basis point equals three billion yen at this scale
In the spring of 2026, Fujitsu and Daiichi Life Group — one of Japan's largest institutional investors — began a year-long inquiry into whether quantum computing can untangle the ancient human problem of allocating wealth wisely under uncertainty. Managing 30 trillion yen across stocks, bonds, and alternative assets, Daiichi Life faces a complexity that strains classical computation: balancing risk, return, regulation, and future obligations all at once. Their partnership is less a product launch than a deliberate act of preparation — planting seeds for a harvest they believe is inevitable, and choosing to share what they learn along the way.
- Traditional computers buckle under the multidimensional weight of optimizing a 30-trillion-yen portfolio across competing constraints — quantum computing promises to explore that vast solution space in ways classical machines simply cannot.
- The financial stakes are precise and staggering: a single basis point improvement in returns would yield 3 billion yen, making even marginal quantum gains worth serious institutional investment.
- The 12-month research program — running April 2026 through March 2027 — moves in careful stages, from algorithm design to quantum simulators to eventual real hardware, ensuring ideas are validated before the technology fully matures.
- Rather than guarding findings as competitive secrets, both companies have committed to publishing results openly, framing this as foundational work for the entire field rather than a proprietary edge.
- The partnership signals a broader race: firms that experiment with quantum finance now, while hardware is still limited, aim to be deployment-ready the moment large-scale quantum computers arrive.
Fujitsu and Daiichi Life Group have launched a year-long collaboration to explore whether quantum computers can solve one of finance's most persistent challenges — how to invest enormous sums wisely across a tangle of competing demands. The partnership runs from April 2026 through March 2027 and targets the development of quantum algorithms capable of optimizing asset allocation across stocks, bonds, and alternative assets, while simultaneously accounting for risk tolerance, regulatory constraints, and the insurer's own future liabilities.
Daiichi Life is Japan's leading institutional investor, managing roughly 30 trillion yen in assets. The motivating arithmetic is stark: a single basis point improvement in returns — one hundredth of a percent — would generate 3 billion yen in additional value. That precision is exactly what makes quantum optimization worth pursuing. Classical computers struggle with this kind of multidimensional problem, particularly when stress-testing decisions across a wide range of economic scenarios. Quantum machines, in theory, can explore vast solution spaces simultaneously in ways their classical counterparts cannot.
The research will unfold in stages — first designing the algorithms jointly, then validating them on quantum simulators, and eventually testing on real quantum hardware. This methodical approach reflects the current state of the technology: powerful enough to study, not yet powerful enough to deploy at full portfolio scale.
What distinguishes this partnership is its openness. Both companies plan to publish their findings through academic channels, treating the work as a contribution to the broader global effort rather than proprietary advantage to be hoarded. In doing so, Fujitsu and Daiichi Life are making a deliberate bet — that the institutions best positioned to benefit from quantum finance are those experimenting now, building readiness for a future they believe is already on its way.
Fujitsu and Daiichi Life Group have begun a year-long collaboration to test whether quantum computers can solve one of finance's most stubborn problems: how to invest 30 trillion yen wisely. The partnership, which runs from April 2026 through March 2027, aims to develop quantum algorithms that can optimize investment decisions across stocks, bonds, and alternative assets—all while juggling competing demands like risk tolerance, regulatory constraints, and the insurance company's own future liabilities.
Daiichi Life is not a small player in this experiment. As Japan's leading institutional investor, the company manages roughly 30 trillion yen in assets. The math here is straightforward and compelling: if quantum optimization could improve returns by just one basis point—a single hundredth of a percent—the company would gain an additional 3 billion yen. That's the kind of precision that makes quantum computing worth the research investment.
The challenge both companies are tackling is genuinely complex. Asset allocation decisions require simultaneous consideration of multiple moving parts: the balance between risk and return, the characteristics of future liabilities, regulatory requirements, and constraints specific to each asset class. Traditional computers struggle with this kind of multidimensional optimization, especially when you layer in the need to stress-test decisions across a wide range of possible economic scenarios. Quantum computers, in theory, can explore vast solution spaces simultaneously in ways classical machines cannot.
Fujitsu has positioned itself as a serious player in quantum technology development, actively pursuing partnerships across industries to move quantum from laboratory curiosity to practical business tool. Daiichi Life, meanwhile, is pursuing its own digital transformation agenda—it wants to become a global top-tier insurance group, and it sees cutting-edge technology as essential to that ambition. The partnership reflects a shared conviction that quantum computing will eventually reshape finance, and that the companies best positioned to benefit are those experimenting now, while the technology is still maturing.
The research will proceed in stages. First, the two companies will jointly design and develop the quantum algorithms themselves. Then they'll test these algorithms using quantum simulators—classical computers that mimic quantum behavior—and eventually on actual quantum hardware. This staged approach is pragmatic: it lets them validate their ideas before quantum computers become powerful enough to handle real-world portfolio sizes.
What makes this partnership notable is its explicit commitment to sharing findings. Both companies plan to publish their insights through academic papers and other channels, contributing to the broader global effort to understand quantum computing's real-world applications. They're not treating this as proprietary research to be hoarded; they're treating it as foundational work that will benefit the entire field.
The deeper implication is that Fujitsu and Daiichi Life are betting on a specific timeline. They're conducting practical verification now, while quantum computers are still relatively small and specialized, because they want to be ready to deploy these technologies at scale the moment large-scale quantum hardware becomes available. In finance, being first often means being best. The companies are essentially preparing for a future they believe is coming, and they're doing it deliberately, methodically, and in the open.

La Conversación del Hearth Otra perspectiva de la historia
Why does a single basis point matter so much that it justifies a year of quantum research?
Because at that scale, one basis point equals three billion yen. When you're managing 30 trillion yen, the math becomes impossible to ignore. Traditional optimization might get you close, but quantum could get you precise.
But quantum computers barely exist yet. Why start now?
That's exactly why. They want to understand the problem deeply before the hardware catches up. When large-scale quantum computers arrive, they won't have time to learn—they'll need to deploy immediately.
What's the actual bottleneck they're trying to solve?
Asset allocation is a puzzle with hundreds of moving pieces: risk, return, regulations, liabilities, constraints on each asset class. Classical computers can optimize one or two dimensions well. Quantum can theoretically hold all of them in mind at once.
Are they publishing their results?
Yes, openly. They're treating this as foundational research, not a competitive advantage. That's unusual for financial work, but it signals they're thinking long-term about the technology itself, not just their own returns.
What happens if quantum computers don't deliver?
Then they've learned something valuable about the limits of the technology, and they've contributed that knowledge to the field. But both companies are betting they will deliver.
