The article seems to suggest it's impossible to communicate faster than light speed using entanglement b/c they need to know a bit of information at the sender's side which can't be sent using the entanglement phenomenon itself.<p>That's something I'd like to understand better..<p>Is it really impossible to distinguish between an 'On' state and an 'Off' state at the receiver's end without this piece of information? Is it our ability to measure the observation that hinders this or is this a law of physics that will 'never' be broken?
