Until now, quantum teleportation (that is, sending quantum data from one place to another) has required a room-filling machine. That's not going to usher in a brave new era of quantum computing, is it? However, a team of British and Japanese researchers has shrunk things down to a much more reasonable size. They've stuffed the core optical circuits for quantum teleportation into a single silicon chip that's just slightly longer than a penny -- in contrast, an experimental device from 2013 was nearly 14 feet long. While scientists built the chip using "state-of-the-art nano-fabrication," it should be more practical to make than its ancestors, which took months.
