Quantum entanglement, the spooky action at a distance that promises to be so useful for things like high-powered computing and security, is generally considered a function of the tiny world. It’s easy — OK, not easy, but relatively practical nowadays — to take two particles or two microscopic things and intertwine their fates. Now for the first time, scientists have accomplished quantum entanglement on the macro scale, entangling two millimeter-sized diamonds.
Over five years ago, scientists succeeded in teleporting information. Unfortunately, the advance failed to bring us any closer to the Star Trek future we all dream of. Now, researchers in Japan have used the same principles to prove that energy can be teleported in the same fashion as information. Rather than just hastening the dawn of quantum computing, this development could lead to practical, significant changes in energy distribution.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
