Monitoring a quantum network on AWS

This article discusses how to set up a monitoring system for a quantum key distribution (QKD) network using AWS services. It covers the steps taken by LuxQuanta, a QKD device manufacturer, to streamline the management of their QKD devices using AWS infrastructure automation tools.

Specifically, the article covers:

• Background on LuxQuanta's continuous-variable QKD (CV-QKD) technology and the need for a classical management layer
• Setting up a QKD device monitoring infrastructure on AWS using the Cloud Development Kit (CDK)
• Provisioning resources like VPC, subnets, load balancer, auto-scaling group, and database
• Monitoring and alarming using Prometheus and Grafana
• Time series database with Prometheus and exporters
• Log management with Loki
• Extracting and monitoring QKD metadata like excess noise, secret key rate, and transmittance
• Example of real-time monitoring and insights for multiple QKD systems
• Conclusion on the benefits of using AWS for QKD network monitoring and management
