Intra-atomic frequency-comb-based photonic quantum memory using single-atom-cavity setup

On-demand and efficient storage of photons is an essential element in quantum information processing long-distance communication. Most the memory protocols require bulk systems order to store photons. However, with advent integrated photonic chip platforms for processing, on-chip memories are highly sought after. In this paper, we propose a protocol multimode using only single-atom-cavity setup. We show that single atom containing frequency comb coupled optical cavity can efficiently. Further, scheme also be used polarization states light. As examples, rubidium cesium atoms nanophotonic waveguide cavities serve as promising candidates realize our scheme. This provides possibility robust chips.
