On the Eve of the Quantum Era: D-Wave Deepens Its Roots in Japan, Revealing the Key Leap from Validation to Operation

From Theoretical Origin to Commercial Frontier: Japan's Unique Position in the Quantum Market

In 1998, Professor Hidetoshi Nishimori of Tokyo Institute of Technology and then-graduate student Masashi Kadowaki published a paper on "quantum annealing." This paper not only laid the foundation of quantum annealing theory, but also became the technological cornerstone of D-Wave, the world's only commercially available annealing quantum computer, years later.

Japan, as the birthplace of quantum annealing theory, now stands at a delicate historical juncture. In January 2026, D-Wave announced the completion of its acquisition of Quantum Circuits, a leading developer focused on error-corrected superconducting gate-model quantum computing systems. This acquisition means that D-Wave will simultaneously possess two technological routes—annealing and gate-model—forming a globally unique dual-platform quantum computing product matrix. And Japan happens to be one of the earliest markets where D-Wave established a subsidiary in its overseas expansion.

In a recent exclusive interview published by JETRO, Shingo Matsushima, Country Manager of D-Wave Japan, elaborated on the attractiveness of the Japanese market, the current progress of quantum applications, and future challenges. Through this dialogue, we can clearly see the deep transformation that Japan's quantum industry is undergoing: moving from research validation toward practical operations, and from point technology breakthroughs toward ecosystem construction.

Industrial Clusters and Early Adoption: Why Japan Has Become a "Natural Testbed" for Quantum Computing

In D-Wave's view, Japan's value lies not only in its status as the world's third-largest economy, but also in its unique industrial structure and academic accumulation. Manufacturing, automotive, electronics, materials science, cutting-edge research—the global competitiveness in these fields makes Japan the ideal cradle for quantum computing application scenarios.

In the interview, Shingo Matsushima pointed out that one of the distinctive features of the Japanese market is the large number of organizations actively adopting quantum computing—from large enterprises and research institutions to universities and government, with extremely broad coverage. This "widespread early adoption" reflects Japan's deep commitment to quantum technology. Particularly noteworthy is that companies in the telecommunications and pharmaceutical industries have begun moving from research to operational applications. This means that quantum computing in Japan is no longer just an exploration in the laboratory, but is entering real scenarios in business processes.

This trend is no accident. Japanese companies' long-standing accumulation in lean manufacturing and complex system optimization makes combinatorial optimization problems—exactly the forte of annealing quantum computers—a natural entry point. Whether it is logistics scheduling, communication network optimization, or drug molecular simulation, Japan's industrial needs are highly aligned with the technical strengths of quantum computing.

From Validation to Operation: The Next Watershed for Japan's Quantum Market

Although Japan ranks among the global leaders in the development of quantum computing application scenarios, Shingo Matsushima also candidly pointed out the current bottleneck: other global markets are rapidly integrating quantum technology into core business operations, and Japan needs to further accelerate in this regard."By strengthening its advantages in research and use-case development, Japan can further reinforce its ecosystem through prioritizing implementation, cross-industry collaboration, and measurable operational outcomes," suggests Shingo Matsushima. This statement reveals a key challenge—Japan's quantum industry still carries a strong "research-driven" character, and moving from proof-of-concept (PoC) projects to production-grade systems requires not only technological maturity but also organizational transformation and innovation in collaboration mechanisms.

This is consistent with the overall pace of Japan's digital transformation that we have observed. Japanese companies tend to pursue extreme precision and low risk in technology adoption. While this is an advantage in certain areas, it can also become a constraint in the rapidly evolving quantum field. How to accelerate the pace of actual deployment while maintaining technical rigor is a challenge that Japan's quantum industry must confront directly.

Dual-Platform Strategy: Injecting New Possibilities into Japan's Quantum Ecosystem

D-Wave's acquisition of Quantum Circuits has brought a new variable to the Japanese market. In the past, D-Wave focused on commercial annealing quantum computers to serve combinatorial optimization problems; meanwhile, Quantum Circuits' expertise in error-corrected gate-model quantum systems is expected to extend computing capabilities to deeper fields such as quantum chemistry and materials science.

Shingo Matsushima believes this acquisition will broaden the application and research opportunities available to Japanese industrial and academic users, creating new pathways for advanced use cases that require near-term optimization capabilities and future gate-model innovation. In other words, Japanese companies and research institutions will be able to access two complementary quantum computing paradigms within the same ecosystem simultaneously, without being tied to different vendors.

This capability is particularly important for Japan's manufacturing and materials industries, which are at a critical juncture of transformation. For example, in fields such as battery materials, catalyst design, and new drug development, gate-model quantum computers—once error correction capabilities are enhanced—are expected to achieve molecular-level simulations that classical computers cannot perform. Meanwhile, the optimization experience previously accumulated on annealing quantum computers can serve as a transitional and complementary step, forming a continuous innovation ladder.

Two-Way Flow: Japan's Strategic Choices in Global Quantum Competition

In the exclusive interview, Shingo Matsushima offered advice to foreign companies entering the Japanese market: leverage global advantages while deeply engaging in local collaboration. "Two-way knowledge exchange is particularly critical—bringing proven international use cases to Japan while showcasing innovations developed in Japan to the global market."

In fact, this statement also applies to Japan's own quantum strategy. In the global quantum race, Japan has both a unique theoretical heritage and a strong industrial base, but if it relies solely on internal circulation, it may become disconnected from the global ecosystem. The D-Wave case shows that overseas companies view Japan not just as a sales market, but also as a partner for co-creating value.Looking deeper, the development logic of the quantum computing industry has transcended single technological breakthroughs and evolved into a comprehensive ecosystem competition involving hardware, software, algorithms, application scenarios, and talent cultivation. Whether Japan can effectively connect its theoretical advantages, industrial strengths, and global collaboration networks will determine its position in the quantum era.

Conclusion: The Leap from "Theoretical Origin" to "Global Leader in Practical Applications"

The era of quantum technology is accelerating. For Japan, this process is full of both opportunities and challenges. D-Wave's continued investment in the Japanese market and the advancement of its dual-platform strategy have injected new momentum into Japan's quantum ecosystem. But the more critical variable lies in Japan itself—how to transform research advantages into operational outcomes, how to break down organizational barriers to promote cross-industry collaboration, and how to establish an irreplaceable position in the global ecosystem.

When the historical legacy of quantum annealing theory meets the practical demands of industrial digitalization, Japan is writing a unique story. In the future landscape of the quantum industry, Japan may no longer be just the source of theoretical innovation but will play the role of a global leader in practical applications. This leap deserves our continued attention.
