Recently I read some main-stream journals reporting about superluminal transport of EM energy; they say that is a quantum effect. For example, Phys. Rev. A 75, 042105 (2007) [4 pages] "Theoretical evidence for the superluminality of evanescent modes" http://pra.aps.org/abstract/PRA/v75/i4/e042105 Annalen der Physik, Volume 17, Issue 5, pages 319–325, May 2008 "Superluminal propagation of evanescent modes as a quantum effect" http://onlinelibrary.wiley.com/doi/...ionid=71EA4DFAA213DD3DB158976C861E2690.d04t01 If the EM energy propagates at faster-than-light speed, then the photon moves at faster-than-light speed because the photon is the carrier of energy. But in the quantum theory, they say there are no concepts about particle's location and velocity, but just probability, or energy eigen states. How to understand the results reported in the above papers?
