This new quantum router proves it's possible to truly guide a quantum signal. The information used is encoded in two different types of polarized photons (like 1s and 0s). Scientists then create a single photon that acts as both (the combined 1s and 0s). That photon is then broken down into two photons that share the combined state. The router picks up one to determine the route, then the other photon is used to transfer the information. A simple series of half mirrors guides the photons along the correct route.
