The transition to the High-Luminosity Large Hadron Collider (HL-LHC) presents a computational challenge, as particle reconstruction complexity may outpace classical computing resources. A 1-bit quantum filter reformulates tracking from matrix inversion to binary ground-state filtering, achieving an asymptotic gate complexity of \({{\mathscr{O}}}(\sqrt{N}\log N)\) given Hamiltonian dimension N.
