Quantum annealing in the NISQ era: railway conflict management

Understand

We are in the Noisy Intermediate-Scale Quantum (NISQ) devices' era, in which quantum hardware has become available for application in real-world problems.

• However, demonstrating the usefulness of such NISQ devices are still rare.
• In this work, we consider a practical railway dispatching problem: delay and conflict management on single-track railway lines.
• We examine the issue of train dispatching consequences caused by the arrival of an already delayed train to the network segment being considered.
