Abstract

In this work, we combine an on-chip, telecom, broadband polarization-entangled photon source with industry-grade flexible wavelength management techniques to build a reconfigurable entanglement distribution quantum network over up to 75 km between up to 8 users. As an application, we implement a multi-user QKD protocol (BBM92) over our network.
