01
// The context
By 2026, autonomous fleets had reached critical density across European metropolises, and legacy traffic-light infrastructure, designed around human reaction times, had become the single biggest bottleneck in urban mobility. The client manages a city of 2.1 million people, with over 4,800 intersections and a social cost of congestion estimated at €340 million a year. The brief demanded a paradigm shift, not incremental optimisation.
02
// The challenge
Coordinating 100,000+ vehicles is an NP-hard combinatorial problem: classical solvers collapse beyond a few hundred variables. The maximum tolerable latency between a trajectory update and vehicle actuation is 18 ms, ruling out any centralised cloud architecture. On top of that, the system had to meet safety-critical fault tolerance: a coordination error at 50 km/h through a dense intersection is not recoverable.
03
// The solution
Zeklar designed a three-tier hybrid architecture. A Qiskit quantum layer runs annealing on D-Wave Advantage hardware to solve macro-clusters of 800–1,200 vehicles in parallel, shrinking the solution space by four orders of magnitude versus classical methods. A Go edge layer, across 220 nodes embedded in the road network, ingests V2X telemetry at 10 ms intervals and applies deterministic local corrections. The WebGL visualisation layer processes two million trajectory segments per second. Everything runs on Kafka with geographically partitioned topics, ensuring fault isolation without cascading failures.

// What made it special
// The process
01
Research & modelling
Historical mobility analysis, fluid-dynamic model definition, and QUBO problem formulation for the annealing layer.
02
Quantum prototype
Benchmarking the hybrid solver on synthetic clusters from 100 to 5,000 vehicles, with iterative embedding optimisation on Pegasus topology.
03
Edge infrastructure
Deployment and stress-testing of 220 Go nodes, latency budget validation under peak load, and systematic fault injection.
04
Pilot & validation
Live rollout on an 18 km corridor with 340 intersections and 90-day continuous monitoring for safety certification.
“We expected an applied research project. Zeklar delivered an operating system for our city. That's an entirely different thing.”
// The impact
VORTEX proved that computational fluid dynamics and quantum computing are no longer academic domains. They're production-ready tools for urban engineering. The consortium will extend the system to the full city network by 2027, with replication across 12 European cities already in negotiation.
