Abstract:

Integrated quantum memory plays a crucial role in large-scale quantum networks. Over the past years, rare-earth ions doped solid-state materials have shown significant advantages in achieving high-performance integrated photonic quantum memory. This kind of photonic quantum memory enables photonic quantum storage to have long storage time, high efficiency, high fidelity, large bandwidth and multimode capacity, and can also be integrated with other quantum functional devices. This paper reviews progress of integrated photonics quantum memories with various devices fabricated in rare-earth ions doped solid-state materials, such as erbium doped silica fibers, titanium-indiffused LiNbO3 waveguides, femtosecond laser micromachining waveguides, and focused ions beam etching photonic devices. It also discusses the merits and potential of those photonics quantum memories and the challenges.

Key words: quantum network, quantum storage, rare-earth ions doped solid-state materials, integration
