Description
Although linear system solvers are not currently part of particle track reconstruction workflow, our work demonstrates how a lightweight quantum linear solver, such as the Harrow-Hassidim-Lloyd (HHL) could be adapted to this context. The HHL quantum algorithm for solving linear systems promises exponential speed-up. We present a novel variant, 1-bit HHL, which reduces phase estimation to a single bit of precision. This simplification replaces costly eigenvalue inversion with a binary-controlled operation, significantly lowering qubit and gate requirements. The method achieves a favorable trade-off between efficiency and accuracy, providing a potential path toward near-term quantum applications in high-energy physics.
