A quantum cryptographic key distribution (QKD) endpoint () includes a QKD receiver and a feedback system (). The QKD receiver receives symbols transmitted over a QKD path. The feedback system () controls a length of the QKD path based on the received symbols.

Systems and methods for implementing path length control for quantum cryptographic systems

A system () and method for the production and distribution of random bits is disclosed. The system uses a truly random source () to generate random data. The random data is sent to an input interface (), which converts the random data to a random bit stream. The random bit stream is coupled from the input interface () to a processor () via bus (). The processor () executes instructions received from memory () and converts the random bit stream into a machine-readable format. The machine-readable random bit stream is sent to network connection () and made available to network (). A remote user () requests a random bit stream from system () over network (). System () sends the requested number of random bits to the remote user (). System () can include other functionality such as accounting procedures, error checking, user authorization, and data archiving to further enhance operation and aid in conducting business involving the production and distribution of random bit streams.

Method and apparatus for the generation and distribution of random bits

A wireless network [includes a number of first wireless terminals configured to operate as cluster heads [by communicating with at least one other cluster head over a relatively long range backbone link [. Each one of the first wireless terminals includes a backbone transceiver. The backbone transceivers may operate in a first frequency range. At least one second wireless terminal is configured to operate as a cluster member [by communicating with an associated cluster head over a local link. Each one of the second wireless terminals includes a cluster transceiver. The cluster transceivers may operate in a second frequency range that is different from the first frequency range of the backbone transceivers. At least one of the first and second wireless terminals includes both a backbone transceiver and a cluster transceiver.
