Particle track reconstruction with noisy intermediate-scale quantum computers

Understand

The reconstruction of trajectories of charged particles is a key computational challenge for current and future collider experiments.

• Considering the rapid progress in quantum computing, it is crucial to explore its potential for this and other problems in high-energy physics.
• The problem can be formulated as a quadratic unconstrained binary optimization (QUBO) and solved using the variational quantum eigensolver (VQE) algorithm.
• In this work the effects of dividing the QUBO into smaller sub-QUBOs that fit on the hardware available currently or in the near term are assessed.
