Future quantum internet could utilize current fiber networks as scientists bring "light to a standstill"

Light is an extremely useful tool for quantum communication, but it has one major disadvantage: it usually travels at the speed of light and cannot be kept in place. A team of scientists at the Vienna University of Technology has now demonstrated that this problem can be solved - not only in strange, unusual quantum systems, but in the glass fiber networks we are already using today.

By coupling atoms to glass fibers light was slowed down to a speed of 180 km/h.
