- Abstract: In Ref. [Katz et al., arXiv:2007.08770 (2020)], we present a mechanism and
optimal procedures for mapping the quantum state of photons onto an optically
inaccessible macroscopic state of noble-gas spins, which functions as a quantum
memory. Here we introduce and analyze a detailed model of the memory operation.
We derive the equations of motion for storage and retrieval of non-classical
light and design optimal control strategies. The detailed model accounts for
quantum noise and for thermal atomic motion, including the effects of optical
mode structure and imperfect anti-relaxation wall coating. We conclude with
proposals of practical experimental configurations of the memory, with
lifetimes ranging from seconds to hours.
