摘要: Secure, semi-classical authentication schemes are presented. An authentication token is generated by applying a pre-determined measurement to a plurality of random quantum states to obtain a sequence of classical measurement outcomes. The token is validated by receiving the classical measurement outcomes and verifying whether the sequence corresponds to a statistically plausible result for the pre-determined measurement of the plurality of quantum states.

摘要: A security system uses a source capable of producing an entangled state of a sensing mode and a reference mode. The sensing mode has a path that enters an area around an object being secured. A state measurement system in the security system can measure a combination of the sensing mode after traversal of the sensing path and the reference mode after traversal of a reference path.

摘要: A method of establishing a shared secret random cryptographic key between a sender and a recipient using a quantum communications channel is described. The method comprises: generating a plurality of random quantum states of a quantum entity, each random state being defined by a randomly selected one of a first plurality of bases in Hilbert space, transmitting the plurality of random quantum states of the quantum entity via the quantum channel to a recipient, measuring the quantum state of each of the received quantum states of the quantum entity with respect to a randomly selected one of a second plurality of bases in Hilbert space, transmitting to the recipient composition information describing a subset of the plurality of random quantum states, analysing the received composition information and the measured quantum states corresponding to the subset to derive a first statistical distribution describing the subset of transmitted quantum states and a second statistical distribution describing the corresponding measured quantum states, establishing the level of confidence in the validity of the plurality of transmitted random quantum states by verifying that the first and second statistical distributions are sufficiently similar, deriving a first binary sting and a second binary string, correlated to the first binary string, respectively from the transmitted and received plurality of quantum states not in the subset, and carrying out a reconciliation of the second binary string to the first binary string by using error correction techniques to establish the shared secret random cryptographic key from the first and second binary strings.

摘要: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the oxidant flow at a rate less than half of its maximum when the coolant temperature is near 0° C.

摘要: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the volumetric oxidant flow at a rate less than two thirds of its maximum when the coolant temperature is near 0° C.
