We’re happy to share our new paper, in which we show how one can spatially stack multiple Laguerre-Gaussian c-swap protocols in free space and determine the similarity among multiple data channels within a single integrated measurement.
This is the first work led by Jakub Wronski, and the main research part is the output of his bachelor’s thesis! Congrats also to Przemysław Litwin, who supported this research.
This work would not have been possible without the financial support of NCN National Science Centre under the Opus grant program (2022/45/B/ST7/01234).
