Teleporting

Scientists in China have managed to teleport information sixteen kilometers using photon entanglement. The scientists entangled two photons of light, then sent one about ten miles from Beijing. When they altered the state of the proton in Beijing, the proton ten miles away changed state in the exact same way at the same time. According to the article, it's one thing to mess about with protons, and quite another to assume that we'll shortly be putting the airlines out of business by teleporting to our vacations in Fiji. (How I wish that weren't the case...flying is not my favorite mode of transportation.) The experiment may yet lead to new computing and communications techniques allowing for faster, more secure transmission of data. Put computer modules inside a cyborg that calculate using entangled protons and you can effectively deprogram that cyborg by removing him or her from the planet - you'd unentangle the protons over distance. Presumably, as technology and knowledge advances, the distances over which protons remain entangled will increase, but still. Would it hurt in some vaguely physical way to have embedded processing modules essentially die inside your head? How easy (or difficult) would it be for someone to modify the protons of your onboard computer - re-entangle them to protons - and therefore programming - they control?

Hacking the Brain

An article at Wired.com suggests that the brain is the next great hacking frontier and contemplates the possibilities for securing neural interface devices. The article focuses on the lack of attention being paid to creating robust security for such hardware as deep brain stimulators used to treat a variety of illnesses, or for the systems being developed that would allow an amputee to mentally control a prosthetic limb. May I just say "story goldmine"? Whether you have a character hacking a cyborg's interfaces in order to commit third person murder, or a futuristic tech shop specializing in security layers for people whose neural implants weren't entirely on the up and up, or whether you character is a hacker who happens , one day, to drop into the wrong brain - there's far too much fun to be had here. In fiction. In reality, I'd rather know that anything wired directly into my brain was safe against some random gold farmer.
