New Technique to Produce Superluminal Pulses

The research team from National Institute of Standards and Technology (NIST) has devised a new method to produce superluminal light pulses. This four-wave mixing novel technique re-structures parts of light pulse, followed by their movement beyond a vacuum. This novel method will enhance the timing of communications signals and to examine the propagation of quantum correlations.
