Currently wondering if the #optical hybrid used to analyze #phase, #amplitude and #polarization in Clivati et al. 2020 https://doi.org/10.1364/OE.378602 can be used (or tweaked) to serve as a #bb84 Bob terminus if suitably sensitive PDs are used.

Very interesting (and open-) accessible #paper about the operation of long-distance fiberlink networks for time and frequency dissemination and optical clock comparisons with a focus on how to address gaps in the data.

I had the pleasure of meeting Anne Amy-Klein on a workshop in Les Houches this Spring, when I was as new to the field of #fiberlinks #metrology and #clocks as I am #newhere now, and I'm still just scratching the surfaces.
