Fully Packaged Multichannel Cryogenic Quantum Memory Module

Realizing a quantum network will require long-lived quantum memories with optical interfaces incorporated into a scalable architecture. Color-center quantum emitters in diamond have emerged as a promising memory modality due to their optical properties and compatibility with scalable integration. However, developing a scalable color-center emitter module requires significant advances in the areas of heterogeneous integration and cryogenically compatible packaging. Here we report on a cryogenically stable and network compatible quantum emitter module for memory use. This quantum emitter module is a significant development towards advanced quantum networking applications such as distributed sensing and processing.
