Quantum mechanics and superluminal signals

[plutherus]

I mentioned a quantum entanglement experiment and some evidence of a signal apparently being faster than light (aka, backwards in time). (See my posts from last week.)

Thanks to E, more info can be found here:

I'll post more thoughts on these once I've had time to digest them a bit :)
