Quantum Supply Chain Risk Modeling Enters the Logistics Mainstream via 1QBit and Fujitsu Collaboration

A Practical Quantum Leap in Supply Chain Management

As quantum computing matured into its second decade of applied research, 2018 began with new momentum in quantum-inspired computing—an emerging category that bridges classical systems with quantum problem-solving methods. In January, one of the standout developments came from the continued collaboration between 1QBit, a Canadian quantum software startup, and Fujitsu, the Japanese tech giant.

The two companies expanded their work to tackle a specific challenge: using quantum-inspired optimization algorithms to model complex risk in global supply chains—a core concern in manufacturing, distribution, and intermodal logistics.

Rather than waiting for fully fault-tolerant quantum computers, this partnership focused on applying the mathematical logic of quantum computing—such as QUBOs (quadratic unconstrained binary optimization problems)—to specialized classical processors with massive parallelism.

In essence, it offered logistics operators a "quantum advantage now" strategy by simulating quantum effects on hardware already capable of large-scale commercial deployment.

Fujitsu’s Digital Annealer Gets Real Supply Chain Use Cases

Central to the collaboration was Fujitsu’s Digital Annealer, launched commercially just months earlier in 2017. By January 2018, the technology had matured enough for pilots in real-time risk evaluation and mitigation within global supply chains.

The Digital Annealer mimics the behavior of a quantum annealer—like those built by D-Wave—but runs on classical silicon. This approach enabled Fujitsu and 1QBit to apply combinatorial optimization methods to critical problems such as:

• Supplier risk mitigation across multiple tiers

• Just-in-time inventory planning under uncertainty

• Shipment routing under stochastic delays

• Dynamic reallocation of orders following disruption events

At the heart of the technology was the QUBO model, which naturally expressed constraints like cost, time, capacity, and reliability—all key to logistics planning.

Industry Trials Kick Off in Manufacturing Hubs

In January 2018, Fujitsu disclosed early-stage deployments of the Digital Annealer system in Japanese and South Korean logistics chains, particularly in the automotive and electronics sectors.

The company’s case study with a major tier-one automotive supplier demonstrated how the Digital Annealer could evaluate over 10^25 possible combinations to find optimal parts delivery sequences under real-time disruption scenarios—such as weather, strikes, or supplier quality failures.

1QBit, which had received significant investment from Accenture and Fidelity, worked alongside Fujitsu to build interfaces that allowed supply chain analysts to input dynamic data from ERPs and IoT devices, converting them into solvable optimization problems in minutes.

By January’s end, pilots had already achieved 20–30% faster risk model convergence, reducing inventory imbalances and enabling better upstream communication with at-risk suppliers.

A Global Vision: Quantum-Inspired, Globally Deployed

The significance of this work in January 2018 extended far beyond Japan and Canada. Fujitsu and 1QBit’s approach created a template for quantum readiness in logistics—enabling global operators to begin building problem definitions in QUBO format, even before true quantum hardware scaled up.

This quantum-influenced modeling is particularly important for:

• Supply chains with high geopolitical exposure (e.g., semiconductors, defense, rare-earth materials)

• Logistics with volatile demand cycles (e.g., fashion, perishable goods)

• Multi-tier, multi-region ecosystems (e.g., pharmaceutical distribution)

At the World Economic Forum in Davos (January 22–26, 2018), Fujitsu’s CTO Joseph Reger highlighted the Digital Annealer during a panel on Resilient Global Supply Chains, calling it a “powerful, near-term path to quantum-class optimization.”

Supply Chain Volatility Demands New Models

Traditional supply chain modeling often fails under extreme variability, where deterministic inputs cannot accurately reflect the real-world uncertainties of:

• Supplier insolvencies

• Natural disasters

• Port closures or congestion

• Customs delays

• Political embargoes

Quantum-inspired systems like Fujitsu’s are built to rapidly re-evaluate massive multivariable matrices when disruption hits. They allow operators to simulate hundreds of thousands of “what-if” scenarios per second—calculating alternative fulfillment routes or backup supplier configurations in real time.

This is especially useful for industries using Just-in-Time (JIT) logistics, where failure to adapt in hours can result in shutdowns costing millions.

In January 2018, reports emerged that a major electronics OEM in Taiwan had begun testing a version of the Digital Annealer for semiconductor component sourcing. The company used the platform to rebalance its risk exposure across Tier-2 and Tier-3 suppliers in China and Southeast Asia.

Blending with AI and Predictive Analytics

While quantum-inspired computing is a powerful tool on its own, the real strength lies in hybrid systems.

Fujitsu’s January 2018 roadmap indicated a strong move toward blending Digital Annealer models with AI/ML pipelines. For logistics use cases, this meant using machine learning to:

• Predict likely disruption events from historical data

• Feed probabilistic forecasts into the annealer

• Output multiple viable recovery strategies for logistics managers

This hybrid model effectively linked predictive logistics AI with quantum-level decision engines, providing a decision-support framework that was dynamic, scalable, and commercially viable.

European Interest and Cross-Vertical Expansion

Across the Atlantic, interest was building in applying quantum-inspired optimization to the European supply chain. In early January 2018, the UK’s Digital Catapult and Innovate UK launched a collaborative inquiry into quantum computing's near-term commercial impacts, with 1QBit's hybrid software stack cited as a leading model.

In Germany, Volkswagen Group—already engaged in quantum R&D with D-Wave—was reported to be evaluating Fujitsu’s annealer for internal parts supply chain modeling. Though not publicly confirmed, insiders at the Berlin Logistics Forum (Jan 15–17, 2018) discussed how quantum-inspired methods could augment existing SAP supply network simulations.

Accelerating the Roadmap to Commercial Quantum Use

The 1QBit–Fujitsu work in January 2018 served as a crucial bridge to full quantum computing for the logistics industry. By expressing logistics problems in quantum-native terms (QUBOs), organizations began preparing their data and infrastructure for a smooth transition once universal quantum computers became commercially viable.

In a white paper released January 2018, 1QBit’s Head of Optimization, Mohammad Amin, emphasized that “the real challenge isn’t just building better quantum hardware—it’s ensuring industry has the problem sets, solvers, and workflows ready to leverage them the moment they arrive.”

Conclusion: Quantum-Inspired Logistics Finds Its Commercial Moment

January 2018 marked a turning point where quantum-inspired optimization exited the lab and entered commercial logistics use. With 1QBit’s software stack and Fujitsu’s Digital Annealer, supply chain operators gained access to a level of risk modeling previously impossible with traditional tools.

From Japanese automotive networks to Taiwanese semiconductor hubs and European OEMs, the logistics world began embracing a new class of computing—rooted in quantum theory, executed on classical hardware, and designed for complexity at planetary scale.

As logistics chains grow longer, denser, and more vulnerable to disruption, tools that can model tens of trillions of outcomes in seconds aren’t just impressive—they’re essential. And thanks to work begun in January 2018, they’re now within reach.
