Long-distance quantum information distribution is hindered by photon loss in optical fibers. While quantum repeaters are proposed as a solution, their complexity limits communication distance. This paper demonstrates coherent storage of light in an atomic frequency comb memory for over one hour using a zero-first-order-Zeeman magnetic field and dynamical decoupling, significantly exceeding previous records (~1 minute). This breakthrough paves the way for large-scale quantum communication using long-lived solid-state quantum memories.
