these were taken from Geordie's blog: http://dwave.wordpress.com/

some of my favorites:

(and the two linked from previous mail...)

indeed!  post-quantum reality is NOW.

this computer is using adiabatic QC, which is different from gate
model, but functionally equivalent (just need more qubits
comparatively).  see http://qist.lanl.gov/pdfs/theory.pdf
"""
Aharonov, et al. [3] showed that a slightly more general formulation
of adiabatic algorithms, when used for quantum-state generation, is in
fact universal for QC. Designing quantum algorithms via quantum-state
generation is a novel and potentially important direction, because it
ties into classical algorithm design techniques using Markov chains
and techniques such as bounds on conductance and spectral gaps. As a
first step, it would be interesting to even give such an algorithm for
solved problems such as quadratic residuosity or discrete logarithms.
