Methods and devices for processing a signal. The methods include supplying to a first modulator a first RF signal and a first optical signal, wherein the first modulator is configured to output a first output signal; generating a first intensity signal that is based on the first output signal, wherein the first intensity signal is further based on a first biasing parameter; and providing a first intensity signal to a first analog-to-digital converter (ADC) to create a first digital signal processable by a signal processing unit.

An umbilical having a plurality of sensors (single, multi-component, or distributed) disposed in a sealed encapsulant, optionally with 'accessories' or connectors at the ends, and the methods or manufacturing and deploying such an umbilical for seismic imaging in geological formations and other applications.

Key management and user authentication systems and methods for quantum cryptography networks that allow for users securely communicate over a traditional communication link (TC-link). The method includes securely linking a centralized quantum key certificate authority (QKCA) to each network user via respective secure quantum links or 'Q-links' that encrypt and decrypt data based on quantum keys ('Q-keys'). When two users (Alice and Bob) wish to communicate, the QKCA sends a set of true random bits (R) to each user over the respective Q-links. They then use R as a key to encode and decode data they send to each other over the TC-link.

A medical voice data system includes a hand-held recording device, an electronic information carrier (EIC), and a host station. The hand-held device records medical information from a user that is examining a person in an extreme environment such as battlefield or disaster area. EICs are stored within a housing interior and can be dispensed therefrom by the user. Recording electronics within the housing interior are operably connected to at least one of the EICs. A microphone is operably connected to the recording electronics to record on a EIC medical information about the injured person. The EIC is configured to be attached to and travel with the person as they are evacuated so that the recorded medical information is immediately available to medical personnel at a care center via the host station. The medical voice data system may also employ a wireless EIC. A host station is used to receive and process the recorded information and convert it to text-based medical record.

Systems and methods for enhanced quantum key distribution (QKD) using an actively compensated QKD system. The method includes exchanging quantum signals between first and second QKD stations and measuring the quantum signal error. An error signal Srepresentative of the system visibility error is then generated. An error-signal threshold Sthat defines a system visibility error limit is then selected. Those qubits measured with the condition S&#x3e;Sare called 'above-threshold' qubits, while those qubits measured with the condition S&#x2266;Sare called 'below-threshold' qubits. Only below-threshold qubits are stored and used to form the final quantum key. This is accomplished by sending a blanking signal Sto the memory unit where the qubits are stored. The blanking signal prevents above-threshold qubits from being stored therein. The raw quantum key so formed has few errors and thus forms a longer final quantum key for a given number of exchanged quantum signals.

A quantum key distribution (QKD) cascaded network with loop-back capability is disclosed. The QKD system network includes a plurality of cascaded QKD relays each having two QKD stations Alice and Bob. Each QKD relay also includes an optical switch optically coupled to each QKD station in the relay, as well as to input ports of the relay. In a first position, the optical switch allows for communication between adjacent relays and in a second position allows for pass-through communication between the QKD relays that are adjacent the relay whose switch is in the first position.

A method for enhancing the security of a quantum key distribution (QKD) system having QKD stations Alice and Bob. The method includes encrypting key bits generated by a true random number generator (TRNG) and sent to a polarization or phase modulator to encode weak optical pulses as qubits to be shared between Alice and Bob. Key bit encryption is achieved by using a shared password and a stream cipher. Bob obtains at least a subset of the original key bits used by Alice by utilizing the same stream cipher and the shared password.

QKD with classical bit encryption

A method of integrating quantum key distribution (QKD) with Internet protocol security (IPSec) to improve the security of IPSec. Standard IPSec protocols impose limits on the frequency at which keys can be changed. This makes efforts to improve the security of IPSec by employing quantum keys problematic. The method includes employing multiple security associations (SA) in in-bound and outbound SA Tables in a manner that enables a high key flipping rate and that enables combining quantum keys with classical keys generated by Internet Key Exchange (IKE), thereby enabling QKD-based IPSec.

Method of integrating QKD with IPSec

Systems and methods for exchanging and processing encoded quantum signals in quantum key distribution (QKD) systems in real time. A stream of quantum signals is sent from Alice to Bob. Alice only encodes sets or 'frames' of the streamed quantum signals based on receiving a 'ready' message from Bob. This allows for Bob to finish processing the previous frame of data by allowing different bit buffers to fill and then be used for data processing. This approach results in gaps in between frames wherein quantum signals in the stream are sent unencoded and ignored by Bob. However, those quantum signals that are encoded for the given frame are efficiently processed, which on the whole is better than missing encoded quantum signals because Bob is not ready to receive and process them.
