# Speed limit of quantum dynamics near the event horizon of black holes

## TL;DR

This paper explores how black holes influence the fundamental quantum speed limit, revealing that the proximity to a black hole's event horizon can significantly enhance the speed of quantum state evolution.

## Contribution

It demonstrates that black holes can drastically alter the quantum speed limit of fermionic systems near the event horizon, a novel intersection of quantum mechanics and general relativity.

## Key findings

- Quantum speed limit increases near black hole horizons.
- Black holes significantly affect quantum dynamical evolution.
- Results connect quantum speed limits with curved spacetime effects.

## Abstract

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.
