A recent experiment [1] shows evidence for strong superluminal group and energy propagation, albeit not for superluminal signal velocity, in light pulses. A few remarks are in order about its implications on the quantum theory of light. 
The effects similar to quantum teleportation and superluminality at propagating of laser pulse in medium with combined nonlinear response
We investigate the phenomena, which are similar to effects of the quantum teleportation and of superluminality, at the two-wave interaction in a medium with the quadratic and cubic nonlinear
On possibility of effect similar to superluminality upon two-frequency interaction in medium with combined nonlinearity
A computer simulation was implemented to study a phenomenon similar to the effect of superluminality appearing upon interaction of two femtosecond pulses in a medium with combined nonlinearity under
Localization of laser pulse and slow light propagation in 2D nonlinear photonic crystal
We investigate optical pulse localization at its propagation in 2D layered photonic crystal (PC) with cubic nonlinear response. In the case under consideration, a light localization takes place due
Localization of laser pulse and slow light propagation in nonlinear photonic crystal
One investigates a light localization at laser pulse propagation in 1D (layered) or 2D nonlinear photonic structure. The light localization takes place due to appearance of spatial solitons which

Gain-assisted superluminal light propagation
TLDR
Gain-assisted linear anomalous dispersion is used to demonstrate superluminal light propagation in atomic caesium gas and is observed to be a direct consequence of classical interference between its different frequency components in an anomalously dispersion region.

The propagation of limited-bandwidth signals, such as Gaussian wave packets, tuned to a transparent spectral region far below the resonance of an inverted two-level atomic medium, can be
Measurement of the single-photon tunneling time.
TLDR
Using a two-photon interferometer, the time delay for a photon to tunnel across a barrier consisting of a 1.1-μm-thick 1D photonic band-gap material is measured, consistent with the group delay («phase time»), but not with the semiclassical time.
VI: Tunneling Times and Superluminality
Publisher Summary Measurements of tunneling times by photons possess certain advantages over those by electrons or other particles, stemming from the fact that the wavelength of visible light is

TLDR
It is shown that a classical Gaussian pulse with such a carrier frequency will propagate at the negative group velocity for many atomic plasma wavelengths, before dispersion deforms the pulse shape.
Causality and negative group delays in a simple bandpass amplifier
We demonstrate a bandpass amplifier which can be constructed from common electronic components and has the surprising property that the group delay is negative in most spectral regions. A pulse
A SUGGESTED INTERPRETATION OF THE QUANTUM THEORY IN TERMS OF "HIDDEN" VARIABLES. II
In this paper, we shall show how the theory of measurements is to be understood from the point of view of a physical interpretation of the quantum theory in terms of hidden variables developed in a

TLDR
Two theorems on the group velocity are presented, one of which is more widely applicable to propagation in waveguides or through multilayer dielectrics, and the other to dispersion in a medium with two resonance lines, where the group speed is abnormal within the absorption line and outside the gain line.
