QuantumTrack: How C12 and Thales Are Using Quantum Annealing to Solve Radar's Hardest Problem

This is your Quantum Computing 101 podcast. A radar screen flickers in Stuttgart, and behind every moving dot lies a problem too complex for any single machine. I’m Leo—Learning Enhanced Operator—and this week, quantum computing stepped closer to the real world. On September 29, French company C12 and defense technology leader Thales announced QuantumTrack, a quantum-classical system for real-time, multi-target radar tracking. It has also won the 2026 Quantum Effects Award in the quantum-computing-hardware category. Here is the challenge. A radar does not simply see aircraft or ships; it receives thousands of pulses, many overlapping, and must determine which observations belong to which object. That becomes a combinatorial optimization problem. The number of possible assignments can explode like sparks from a struck wire. QuantumTrack uses a method called multiple-hypothesis tracking. Classical software first breaks the enormous problem into smaller pieces. Those subproblems are then translated into graphs and sent to a quantum annealer, which searches for low-energy configurations—the arrangements that best satisfy the tracking constraints. The classical system gathers those partial answers, maps them back onto the original problem, and merges them into a coherent picture. That division of labor is the essential lesson. Classical computers are exceptional at memory, data movement, control logic, and stitching results together. Quantum processors are promising as specialized search engines, exploring certain landscapes through quantum effects rather than testing every possibility one by one. Think of it as a modern rescue operation. The classical computer is the command center, sorting maps and coordinating teams. The quantum processor is the scout entering the fog, rapidly examining the hardest intersections and returning with promising routes. Neither replaces the other; together, they turn confusion into a decision. According to The Quantum Insider, tests on C12’s Callisto emulator matched the best classical solver’s time to solution and ran about one hundred times faster than competing quantum annealers in the reported benchmark. The companies estimate an end-to-end runtime near fifty milliseconds, including decomposition, quantum processing, and recombination. QuantumTrack is currently at Technology Readiness Level 5, with a physical-processor demonstration targeted at Level 6. The timing matters. This week, researchers and industry are not presenting quantum computers as magical replacements for supercomputers. At UMass Amherst’s NeSQom workshop, researchers also examined hybrid networks connecting quantum processors, sensors, communication systems, and classical infrastructure. That is where I see the future: not a quantum machine alone, but a living computational ecosystem. CPUs organize, GPUs accelerate, and QPUs attack carefully selected bottlenecks. The breakthrough is not choosing one world. It is learning how to make them cooperate. Thank you for listening.
