Key Points

The integration of quantum cryptography and quantum memory allows for enhanced communication security.
This protocol successfully meets stringent requirements for storage-and-retrieval efficiency and low error rates.
Demonstrated advancements utilize cold-atom technology to achieve efficient data storage in quantum systems.
Implications of the findings point to improved reliability in secure communications using quantum technologies.

Implication

Demonstration combines a quantum cryptographic protocol and quantum memory layer, highlighting its efficiency and reliability.

Abstract

We report the first demonstration of a quantum cryptographic protocol incorporating a quantum memory layer. The protocol imposes strigent requirements on the memory storage-and-retrieval efficiency and on the error rate of the communication.
