This is a good read. I like to read journal articles about things that hopelessly baffle me. This often makes me feel secure, like holding a stuffed animal.
3.1.7. Explore Superluminal Tunneling. A pre-requisite to faster-than-light travel is to prove faster-than-light information transfer. The phenomenon of quantum tunneling, where signals appear to pass through barriers at superluminal speed, is often cited as such empirical evidence. Experimental and theoretical work was sponsored to explore the special case where energy is added to the barrier (tunnel). Even in this case it was found that the information transfer rate is still only apparently superluminal, with no causality violations. Although the leading edge of the signal does make it through the barrier faster, the entire signal is still light-speed limited [3-5]. Although other quantum phenomena still suggest faster-than-light connections (e.g. quantum entanglement), the venue of quantum tunneling does not appear to be a viable approach for exploring faster-than-light propulsion.
