A Simple Approach to Error Reconciliation in Quantum Key Distribution
We discuss the error reconciliation phase in quantum key distribution (QKD)
and analyse a simple scheme in which blocks with bad parity (that is, blocks
containing an odd number of errors) are discarded. We predict the performance
of this scheme and show, using a simulation, that the prediction is accurate.Comment: 19 pages. Presented at the 53rd Annual Meeting of the Australian
Mathematical Society, Adelaide, Oct 1, 2009. See also

Some comments on C. S. Wallace's random number generators
We outline some of Chris Wallace's contributions to pseudo-random number
generation. In particular, we consider his idea for generating normally
distributed variates without relying on a source of uniform random numbers, and
compare it with more conventional methods for generating normal random numbers.
Implementations of Wallace's idea can be very fast (approximately as fast as
good uniform generators). We discuss the statistical quality of the output, and
mention how certain pitfalls can be avoided.Comment: 13 pages. For further information, see
