TL;DR: In this article, the authors proposed an OAM complex spectrum analyzer that enables simultaneous measurements of the power and phase distributions of OAM modes by employing the rotational Doppler effect.

TL;DR: The detrimental effects of unstable fiber birefringence are overcome by employing the reference-frame-independent QKD protocol for polarization qubits in polarization maintaining fiber, where standardQKD protocols fail, as it opens the way for quantum enhanced secure communications between companies and members of the public equipped with handheld mobile devices, via telecom-fiber tethering.

TL;DR: In this article, an OAM complex spectrum analyzer was proposed to measure the power and phase distribution of OAM modes simultaneously by employing rotational Doppler Effect (DoE).

TL;DR: In this article, a one-dimensional discrete-time quantum random walk with orbital angular momentum (OAM) of photons was implemented. But the three steps of the random walk were implemented in the protocol were different from the classical random walk.

TL;DR: In this paper, the authors present a theoretical model to sufficiently investigate the optical rotational Doppler effect based on modal expansion method and find that the frequency shift content is only determined by the surface of a spinning object and the reduced DoP shift is linear to the difference of mode index between input and output orbital angular momentum (OAM) light.
