  - "<jats:p>\r\n                    We develop a framework for identifying nonclassical
    speedups in systems with polarization, likewise spin degrees of freedom. By confining
    the dynamics to the manifold of angular momentum coherent states, which act as
    the classical reference in this case, we compute the speed limit that bounds the
    rate of change of the state achievable without generating quantum coherence. A
    comparison with the unrestricted quantum speed limit enables the quantitative
    identification of speedups arising from polarization nonclassicality. We apply
    this framework to the cross-Kerr interaction, demonstrating a persistent speedup
    scaling as\r\n                    <a:math xmlns:a=\"http://www.w3.org/1998/Math/MathML\">\r\n
