TL;DR: It is observed that a quantum coherence effect, coherent population oscillations, produces a very narrow spectral "hole" in the homogeneously broadened absorption profile of ruby, which leads to a large value of the group index.

TL;DR: A proof-of-principle experiment that indicates the feasibility of high-dimensional QKD based on the transverse structure of the light field allowing for the transfer of more than 1 bit per photon and demonstrates that, in addition to having an increased information capacity, multilevel QK D systems based on spatial-mode encoding can be more resilient against intercept-resend eavesdropping attacks.

TL;DR: A pragmatic introduction to the weak value in terms of measurable quantities is presented in this paper, along with an explanation for how it can be determined in the laboratory and its application to three distinct experimental techniques is reviewed.

TL;DR: This demonstration of entanglement in an angular basis establishes that angles are genuine quantum observables and can therefore be considered a resource for quantum information processing, capable of secure, high-dimension, key distribution.

TL;DR: In this article, a cancellation of absorption occurs on resonance for two (or any even number of) coupled optical resonators, due to mode splitting and classical destructive interference, particularly when the resonator finesse is large and the loss in resonator farthest from the excitation waveguide is small.
