Advanced light: Sending entangled beams through fast-light materials

Posted: 25 May 2014 12:53 PM PDT

Whole beams, not just particles, can be entangled. This, plus anomalous dispersion in 'fast-light' materials, allows signals be to 'advanced' over signals travelling in vacuum, at least in a limited sense.

New method for propulsion in fluids: Researchers discover a way for temperature gradients in fluids to move objects
