Patent number: 10972189Abstract: Multiple bit values can be encoded on a single photon in a quantum key distribution (QKD) system using a plurality of sidebands of an optical carrier frequency. Computational and conjugate bases can be defined, and photons decoded based on a selected state from either basis. If n sidebands are available, as many as log2n bits can be encoded on a single photon. Errors in detected bit values due to selection of an incorrect basis state or other errors can be at least partially corrected by bit distillation to identity bit strings for which a transmitter and a receiver record the same values, without insecure transmission of these values.Type: GrantFiled: January 21, 2020Date of Patent: April 6, 2021Assignee: Triad National Security, LLCInventors: Jane E. Nordholt, Richard J. Hughes, Raymond T. Newell, Charles G. Peterson, Rolando D. Somma

Patent number: 9887976Abstract: Multi-factor authentication using quantum communication (“QC”) includes stages for enrollment and identification. For example, a user enrolls for multi-factor authentication that uses QC with a trusted authority. The trusted authority transmits device factor information associated with a user device (such as a hash function) and user factor information associated with the user (such as an encrypted version of a user password). The user device receives and stores the device factor information and user factor information. For multi-factor authentication that uses QC, the user device retrieves its stored device factor information and user factor information, then transmits the user factor information to the trusted authority, which also retrieves its stored device factor information.Type: GrantFiled: August 16, 2013Date of Patent: February 6, 2018Assignee: Los Alamos National Security, LLCInventors: Richard John Hughes, Charles Glen Peterson, James T. Thrasher, Jane E. Nordholt, Jon T. Yard, Raymond Thorson Newell, Rolando D. Somma
