Science team see the light.
The technology could also lead to the development of ways of communicating over long distances without fear of eavesdropping.
A light pulse was brought to a standstill by a team at Harvard University in Massachusetts.
It's the first time light has been trapped while keeping its electromagnetic energy intact.
It opens up the possibility of harnessing packets, or quanta, of light to store and process data.
The researchers say it could pave the way for quantum computers, which would be able to do mindboggling calculations.
Harvard's Dr Mikhail Lukin said: ``We have succeeded in holding a light pulse still without taking all the energy away from it.''
The light was only trapped for a few hundredths of a millisecond but in optical terms, that is a long time.
