Light and divergences: History and outlook
Gerd Leuchs, Luis L. Sanchez-Soto
All experimental evidence {indicates} that the vacuum is not void, but filled with something truly quantum. This is reflected by terms such as {zero-point} fluctuations, and Dirac'…
Sampling the spatial coherence of light
M. Vitek, M. Peterek, D. Koutny +6
We introduce a novel application of the Hartmann sensor, traditionally designed for wavefront sensing, to measure the coherence properties of optical signals. By drawing an analogy…
Robust quantum metrology with random Majorana constellations
A. Z. Goldberg, J. R. Hervas, Ãngel S Sanz +8
Even the most classical states are still governed by quantum theory. A number of physical systems can be described by their Majorana constellations of points on the surface of a sp…
Quantum multiphase estimation
Marco Barbieri, Ilaria Gianani, Aaron Z. Goldberg +1
Quantum phase estimation is fundamental to advancing quantum science and technology. While much of the research has concentrated on estimating a single phase, the simultaneous esti…
