Tian Zhong, Hongchao Zhou, Ligong Wang, Gregory Wornell, Zheshen Zhang, Jeffrey Shapiro, Franco N. Wong, Rob Horansky, Varun Verma, Adriana Lita, Richard Mirin, Thomas Gerrits, Sae Woo Nam, Alessandro Restelli, Joshua Bienfang, Francesco Marsili, Matthew Shaw


We demonstrate two high-dimensional QKD protocols - secure against collective Gaussian attacks - yielding up to 8.6 secure bits per photon and 6.7 Mb/s throughput, with 6.9 bits per photon after transmission through 20 km of fiber.
