depends on how faithful you need it. We sloppily simulate QED on classical computers just fine (not in real time though). Sloppy simulation only needs to sloppily produce observations that are being done by an experimentalist, and even that ultimately happens in classical domain. They may have precomputed a bunch of stuff since before photoelectric effect was discovered. EPR/Bell tells you nothing if the simulation is non-local. Yes, it's instructive to compare quantum limits on computation with thermodynamic ones. https://plus.google.com/+OlegZabluda/posts/LVeboW9xq5f
Munroe is being uncharacteristically stupid. They didn't dig a canal because 1. There is no way to dig a canal. 2. They can't pump ocean through the borehole 3. If they could, ocean would lose. 4. They didn't want to mess with the Devil.
"Yesterday (Feb 5 2014) NBC News ran a story claiming that if you bring your mobile phone or laptop to the Sochi Olympics, it'll immediately be hacked the moment you turn it on. The story was fabricated. The technical details relate to going to the Olympics in cyberspace (visiting websites), not going to there in person and using their local WiFi."
Nothing to see here, move along, business as usual.
