A glass fiber that brings light to a standstill
By coupling atoms to glass fibers light was slowed down to a speed of 180 km/h. The team even managed to bring the light to a complete stop and to retrieve it again later. This technology is an important prerequisite for a future glassfiber-based quantum-internet, in which quantum information can be teleported over great distances.
"Quantum physics allows us to create a connection between sender and receiver, which makes eavesdropping impossible", says Arno Rauschenbeutel. "The fundamental laws of quantum physics make sure that no one can tap the connection without being noticed."
