This paper is a case study of a general method for designing generators of repeatable non-Poisson sequences of pseudorandom pulses. A class of normal distributions and some classes of skew distributions are derived. Block diagrams and design guides are given. The study is based both on analytical and simulation approaches. Applications of the proposed system may be found in the field of hardwar...

We propose a decoy-pulse method to overcome the photon-number-splitting attack for Bennett-Brassard 1984 quantum key distribution protocol in the presence of high loss: A legitimate user intentionally and randomly replaces signal pulses by multiphoton pulses (decoy pulses). Then they check the loss of the decoy pulses. If the loss of the decoy pulses is abnormally less than that of signal pulse...
