| contents | The emerging hard X-ray - nuclear interfaces offer unique potential advantages over traditional optical-atomic interfaces for room-temperature, solid-state quantum information processing, including lower background noise, tighter focusing, and exceptionally high resonance quality. Leveraging such interfaces, a major milestone was recently achieved with the first implementation of nuclear quantum memory in the hard X-ray range [S. Velten et al., Nuclear quantum memory for hard X-ray photon wave packets, Sci. Adv. 10, eadn9825 (2024)] using the Doppler frequency comb protocol. However, this approach relies on the synchronous mechanical motion of multiple nuclear absorbers, posing experimental challenges for on-demand photon retrieval. We propose an on-demand hard X-ray quantum memory based on reversing the direction of an external magnetic field in a single stationary solid-state nuclear absorber with sets of Zeeman sublevels. This scheme is exemplified by the quantum storage of an 1.41-$μ$s single photon wave packet at 6.2 keV for over 10 $μ$s in a $^{181}$Ta metallic foil, providing a feasible pathway for the first experimental demonstration of on-demand hard X-ray photon storage. |
