Patent number: 11442698Abstract: Random number generators include a thermal optical source and detector configured to produce random numbers based on quantum-optical intensity fluctuations. An optical flux is detected, and signals proportional to optical intensity and a delayed optical intensity are combined. The combined signals can be electrical signals or optical signals, and the optical source is selected so as to have low coherence over a predetermined range of delay times. Balanced optical detectors can be used to reduce common mode noise, and in some examples, the optical flux is directed to only one of a pair of balanced detectors.Type: GrantFiled: January 21, 2020Date of Patent: September 13, 2022Assignee: Triad National Security, LLCInventors: Jane Elizabeth Nordholt, Richard John Hughes, Raymond Thorson Newell, Charles Glen Peterson

Patent number: 10574461Abstract: Message authenticators for quantum-secured communications facilitate low-latency authentication with assurances of security. Low-latency message authenticators are especially valuable in infrastructure systems where security and latency constraints are difficult to satisfy with conventional non-quantum cryptography. For example, a message transmitter receives a message and derives an authentication tag for the message based at least in part on an authenticator that uses one or more quantum keys. The message transmitter outputs the message and its authentication tag. A message receiver receives a message and authentication tag for the message. The message receiver derives a comparison tag for the message based at least in part on an authenticator that uses one or more quantum keys. The message receiver checks whether the message is authentic based on a comparison of the authentication tag and the comparison tag. In example implementations, the authenticator uses stream-wise cyclic redundancy code operations.Type: GrantFiled: September 30, 2014Date of Patent: February 25, 2020Assignee: Triad National Security, LLCInventors: Richard John Hughes, Jane Elizabeth Nordholt, Charles Glen Peterson, Kush T.

Patent number: 10291399Abstract: Quantum secure communication systems communicate quantum signals for quantum key distribution and classical signals with encrypted data and commands via a single optical fiber. In some systems, the single fiber carries classical data in both directions along with quantum communications. For example, quantum keys can be used to encrypt packets for bidirectional communication between two parties. In other systems, a single fiber is used for one way classical communications and quantum communications. The communication systems are secured using a security parameter based on the quantum and classical communications across the optical fiber.Type: GrantFiled: September 30, 2014Date of Patent: May 14, 2019Assignee: Traid National Security, LLCInventors: Jane Elizabeth Nordholt, Richard John Hughes, Charles Glen Peterson, Raymond Thorson Newell

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.

Patent number: 9866379Abstract: Quantum communication transmitters include beacon lasers that transmit a beacon optical signal in a predetermined state of polarization such as one of the states of polarization of a quantum communication basis. Changes in the beacon polarization are detected at a receiver, and a retarder is adjusted so that the states of polarization in a received quantum communication optical signal are matched to basis polarizations. The beacon and QC signals can be at different wavelengths so that the beacon does not interfere with detection and decoding of the QC optical signal.Type: GrantFiled: August 31, 2012Date of Patent: January 9, 2018Assignee: Los Alamos National Security, LLCInventors: Jane Elizabeth Nordholt, Raymond Thorson Newell, Charles Glen Peterson, Richard John Hughes

Patent number: 9819418Abstract: Security is increased in quantum communication (QC) systems lacking a true single-photon laser source by encoding a transmitted optical signal with two or more decoy-states. A variable attenuator or amplitude modulator randomly imposes average photon values onto the optical signal based on data input and the predetermined decoy-states. By measuring and comparing photon distributions for a received QC signal, a single-photon transmittance is estimated. Fiber birefringence is compensated by applying polarization modulation. A transmitter can be configured to transmit in conjugate polarization bases whose states of polarization (SOPs) can be represented as equidistant points on a great circle on the Poincaré sphere so that the received SOPs are mapped to equidistant points on a great circle and routed to corresponding detectors.Type: GrantFiled: August 16, 2013Date of Patent: November 14, 2017Assignee: Los Alamos National Security, LLCInventors: Jane E.

Patent number: 9680641Abstract: Techniques and tools for quantum key distribution (“QKD”) between a quantum communication (“QC”) card, base station and trusted authority are described herein. In example implementations, a QC card contains a miniaturized QC transmitter and couples with a base station. The base station provides a network connection with the trusted authority and can also provide electric power to the QC card. When coupled to the base station, after authentication by the trusted authority, the QC card acquires keys through QKD with a trust authority. The keys can be used to set up secure communication, for authentication, for access control, or for other purposes. The QC card can be implemented as part of a smart phone or other mobile computing device, or the QC card can be used as a fillgun for distribution of the keys.Type: GrantFiled: April 6, 2015Date of Patent: June 13, 2017Assignee: Los Alamos National Security, LLCInventors: Jane E.

Publication number: 20160380765Abstract: The present invention provides a quantum-enabled security (QES) protocol which creates a revolutionary new cybersecurity capability: quantum (single-photon) communications are integrated with optical communications to provide a strong, innate security foundation at the photonic layer for optical fiber networks or free-space optical communications. The new protocols will also allow the formation of ad hoc coalitions of users in order to deliver quantum-enabled security users between users who may not have direct quantum communications.Type: ApplicationFiled: April 22, 2016Publication date: December 29, 2016Inventors: Richard John Hughes, Charles Glen Peterson, Jane Elizabeth Nordholt, Raymond Thorson Newell, Peter C.

Patent number: 9287994Abstract: Birefringence in optical fibers is compensated by applying polarization modulation at a receiver. Polarization modulation is applied so that a transmitted optical signal has states of polarization (SOPs) that are equally spaced on the Poincaré sphere. Fiber birefringence encountered in propagation between a transmitter and a receiver rotates the great circle on the Poincaré sphere that represents the polarization bases used for modulation. By adjusting received polarizations, polarization components of the received optical signal can be directed to corresponding detectors for decoding, regardless of the magnitude and orientation of the fiber birefringence. A transmitter can be configured to transmit in conjugate polarization bases whose SOPs can be represented as equidistant points on a great circle so that the received SOPs are mapped to equidistant points on a great circle and routed to corresponding detectors.Type: GrantFiled: August 31, 2012Date of Patent: March 15, 2016Assignee: LOS ALAMOS NATIONAL SECURITY, LLCInventors: Jane Elizabeth Nordholt, Charles Glen Peterson, Raymond Thorson Newell, Richard John Hughes
