Subject: Re: OT: Light Stopped, Stored, And Sent On Its Way
Yes, there is a distinction. The way the physicists stopped the light
retains all the quantum information. In a normal recording, you can only
measure some aspects of a photon's quantum state and lose all the other
information. With a normal recording, you can play back what you measured
any number of times. With the stopped light, once it is played back, all
the information is gone.
