Excited to share our latest work as part of the Allegro Project—an innovative step toward optimizing the co-existence of Quantum Key Distribution (QKD) and classical optical communication on the same fiber infrastructure.

🔍 What we did:
We developed a novel machine learning-based framework to predict the performance of a QKD-classical channel co-existence system. This system intelligently factors in:

  • 📡 Number and power of classical channels
  • 🧵 Fiber length
  • 📊 Channel frequency placement

📌 Our scenario setup:

  • 1 QKD channel @ 193.2 THz (1551.72 nm)
  • 11 classical channels in the C-band:
    • 5 between 192.80 – 193.00 THz
    • 6 between 193.40 – 193.65 THz

🧠 Our solution:
We implemented an Artificial Neural Network (ANN) with:

  • 1 input layer
  • 2 hidden layers
  • 1 output layer

🧪 Training dataset:
A diverse set of 16,654 co-existence scenarios, varying in:

  • Channel powers
  • Fiber distances
  • On/off configurations

This approach helps forecast and optimize QKD performance in real-world network conditions—moving us closer to secure, scalable quantum-enhanced communication.

Kudos to the team and collaborators who made this possible! 👏
