Photon-Efficient High-Dimensional Quantum Key Distribution

Not Accessible

Your library or personal account may give you access

Abstract

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.
