Open AccessThe information of high-dimensional time-bin encoded photons
High-dimensional entanglement is an important physical resource for quantum communication. A basic issue for any communication scheme is how many shared bits two parties can extract subject to experimental no...

Superluminal Communication in Quantum Mechanics
One consequence of the special theory of relativity is that no information can be transmitted between two parties in a time shorter than it would take light, propagating through vacuum, to travel between the p...

Causality in Superluminal Pulse Propagation
The theory of electromagnetism for wave propagation in vacuum, as embodied by Maxwell’s equations, contains physical constants that can be combined to arrive at the speed of light in vacuum c. As shown by Einstei...

Solitons go slow
A new method for slowing down light pulses while minimizing pulse distortion could help create practical photonic devices that route bits of information in optical-telecommunication systems.

Pulse propagation in a high-gain bichromatically-driven Raman amplifier
Using intense electromagnetic fields, it is now possible to tailor the absorption. amplification, and dispersion properties of multi-level atoms [1]. Dramatic examples include the reduction of the group velocity ...

Dynamics of a two-photon laser
The high degree of temporal coherence of laser light arises from a complex interplay between the fundamental light-matter interactions of absorption, spontaneous emission, and stimulated emission. The coherenc...

A Novel Technique for Resonantly Enhanced Sum-Frequency Generation Involving Rydberg Atomic States
Experimental evidence is presented that demonstrates the usefulness of atomic Rydberg states in resonantly enhanced, nonlinear optical mixing. This work provides verification of a recent prediction that large ...
