| Overcoming qubit-based QKD with efficient high-dimensional encoding | QCRYPT 2020 | regular | Ilaria Vagniluca, Davide Rusca, Daniele Cozzolino, Yunhong Ding, Hugo Zbinden, Alessandro Zavatta, Leif Katsuo Oxenløwe, Davide Bacco |
We experimentally tested an alternative fiber-based setup for 4D-QKD, with time and phase encoding and one-decoy technique. We evaluated the secret key rate achievable in a finite-key scenario and we compared it with the binary-encoded BB84 protocol, which was tested with the same experimental setup. Our 4D-QKD system makes it possible to improve the secret key rate by more than a factor 2 in the saturation-regime of single-photon detectors, without requiring additional expensive resources to the 2D-QKD setup. In comparison to previous works, our scheme allows to measure the 4D states with a simplified and compact receiver, thus making it a cost-effective solution for practical and fiber-based QKD. |
