Quantum anything has typically fallen into our oft-used category of 'awesome things that'll never happen,' but if a crew of researchers at the California Institute of Technology have anything to say about it, they'll soon be changing the fortunes of that segment. The team has recently demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories, and while that probably just blew your mind a little bit, the breakdown is fairly interesting. Essentially, they've uncovered a quantum interface between the atomic memories, which is said to "represent something akin to a computer hard drive for entanglement." If extended, it could pave the way toward quantum networks, and in turn, massive webs of quantum computers. We're obviously decades out from understanding what this all means for the common computer user, but just remember this: "for an entangled quantum system, there exists no objective physical reality for the system's properties." And you thought The Matrix was deep.
I don't even know what half of that means, but it sounds awesome.
