How To Make a Quantum Bit. Did government scientists really create a secret quantum internet? Scientists ‘freeze’ light for an entire minute. Light completely stopped for a record-breaking minute - physics-math - 25 July 2013. The fastest thing in the universe has come to a complete stop for a record-breaking minute.
At full pelt, light would travel about 18 million kilometres in that time – that's more than 20 round trips to the moon. "One minute is extremely, extremely long," says Thomas Krauss at the University of St Andrews, UK. "This is indeed a major milestone. " The feat could allow secure quantum communications to work over long distances.
