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