Quantum mechanics imposes a fundamental bound on the minimum time required for the quantum systems to evolve between two states of interest. This bound introduces a limit on the speed of the dynamical evolution of the systems, known as the quantum speed limit. We show that black holes can drastically affect the speed limit of a two-level fermionic quantum system subjected to an open quantum dynamics. As we demonstrate, the quantum speed limit can enhance at the vicinity of a black hole's event horizon in the Schwarzschild spacetime.

  1. Probing the quantum speed limit and entanglement in flavor oscillations of neutrino-antineutrino system in curved spacetime

    gr-qc 2025-04 reject novelty 5.0 of 10

    Gravity-induced neutrino-antineutrino oscillations near a rotating primordial black hole are computed in Kerr-Schild polar coordinates, with quantum speed limit and entanglement entropy estimated.
