      abstract     = {Particle track reconstruction plays a crucial role in the
                      exploration of new physical phenomena, particularly when
                      rare signal tracks are obscured by a significant background.
                      In muon colliders where beam muons interacting with the
                      detector produce secondary and tertiary background
                      particles, track reconstruction can be computationally
                      intensive due to the large number of detector hits. The
                      formulation of the reconstruction task as Quadratic
                      Unconstrained Binary Optimisation (QUBO) enables the use of
                      quantum computers, which are believed to offer an advantage
                      over classical computers in such optimisation
                      scenarios.Timing information provided by the tracker is a
                      key element in suppressing the large background at muon
                      colliders. The QUBO parameters are determined by combining
                      spatial and temporal information from detector hits,
                      resulting in a 4D quantum algorithm.To demonstrate the
                      effectiveness of this approach, the quantum algorithm is
                      used to reconstruct signal tracks from samples consisting of
                      Monte Carlo simulated charged particles overlaid with
                      background hits. I will present the obtained reconstruction
                      performance and discuss possible paths for further
                      improvements.},
