It's a lot more impressive than most whitepaper-y publications on the topic.
You could also look at the Comscire one, they also publish a fair bit of info
on them, including test results.  However, both of them seem to build a bit
heavily on the magic of quantum.  Still, the Whitewood one seems more 
quantum-y than the Comscire one.
