A quantum computer spotted particle paths in LHCb collisions
Researchers at Nikhef Maastricht ran a track-finding task from LHCb collision data on a quantum computer. The quantum approach produced results comparable to conventional reconstruction methods. This shows a quantum computer can perform a pattern-recognition step used in particle physics.

This could enable quantum-accelerated pattern matching to be added as a drop-in subroutine for track seeding in LHCb's offline reconstruction, targeting events where classical methods face combinatorial ambiguity.
The demonstration already reached parity on a simplified track-finding task, so the immediate bottleneck is integration and scaling rather than proving the concept. If the algorithm can be mapped to currently accessible noisy quantum processors and coupled to LHCb's existing reconstruction software within the next two years, selected high-ambiguity events could be offloaded without fault-tolerant hardware.
