Big brains across the globe continue to unlock the secrets of the qubit and harness it for myriad uses -- quantum hard drives quantum computers , and even quantum refrigerators . The internet may be next in line to get quantum-ized now that researchers from Northwestern University found a way to route a photon qubit through an optical cable without losing any of its physical characteristics. A newly developed optical switch does the deed, which allows fiber-optic cables to share multiple users' quantum info at once -- making superfast all-optical quantum communication networks possible -- and gets us closer to having our tweets and status updates whizzing to and fro at the speed of light.[Thanks, Jonathan C]
