At the University of Bristol, we’re pushing the boundaries of entanglement-based Quantum Key Distribution (QKD) with our novel q-ROADM architecture—designed to bring flexibility and scalability to quantum networks.
🔑 How it Works:
✨ Utilizes a broadband SPDC source for entanglement generation.
🔹 DEMUX splits the entangled photon spectrum into 30 x 100 GHz ITU channels.
🔸 Optical Fiber Switch (OFS) provides dynamic control.
🔹 MUX/Wavelength Selective Switch (WSS) recombines photons into a single fiber for efficient bipartite entanglement sharing.
🔸 Each user is equipped with a polarization analysis module for executing the BBM92 QKD protocol.
By integrating DEMUX, OFS, and MUX/WSS, our q-ROADM enables real-time network reconfiguration, adapting to any topology across time and wavelength domains. This innovation paves the way for scalable, high-performance quantum-secure communication.
Excited to share more insights—stay tuned! 🚀🔑
