Abstract

The quantum digital signature protocol offers a replacement for aspects of public-key digital signatures. Here, we demonstrate and characterize hardware to implement entanglement-based quantum digital signatures over our campus network, validating use in deployed fiber.

Funding

We thank Benjamin Lawrie for sharing some lab space and several single-photon detectors for the deployed fiber measurements. Also, we thank Joseph Lukens for his design contributions to the White Rabbit synchronization network and, alongside Brian Williams, to the development of the timetagger. This work was performed at Oak Ridge National Laboratory, operated by UT-Battelle for the U.S. Department of Energy under contract no. DE-AC05-00OR22725. Funding was provided by the U.S. Department of Energy, Office of Cybersecurity Energy Security and Emergency Response (CESER) through the Risk Management Tools and Technologies (RMT) Program.
