Long-Distance Quantum Key Distribution Supported by a PIC-Based Interferometer (W2A.4)
Presenter: Davide Bacco, University of Florence
We demonstrate QKD with efficient-BB84 protocol employing a photonic integrated Mach-Zehnder interferometer in the receiver. Our solution outperforms fiber-based devices, covering a 45 dB link and achieving a 220% higher key rate at 10 dB.
