Delivering quantum information – a field-deployed quantum network

The article discusses a field-deployed quantum network developed jointly by researchers from Harvard University and the AWS Center for Quantum Networking (AWS CQN). This network can distribute, store, and process quantum information over long distances using existing fiber optic infrastructure.

Specifically, the article covers:

• The importance of quantum networks for enabling communication between quantum computers and sharing quantum information securely
• The use of silicon vacancy centers (SiVs) in diamond as quantum memories to store and process quantum information in the network nodes
• The successful demonstration of entanglement between two quantum memories located 35 km apart using a deployed fiber network in the Boston area
• Challenges and future steps required for scaling quantum networks, including multiplexing, improving fidelity, and enabling higher operating temperatures
• The potential of quantum communication technology for enabling secure communication and networked quantum computing in the future
