Closing the Detection Loophole in the Triangle Network with High-Dimensional Photonic States
Author(s): Tamás Kriváchy and Martin Kerschbaumer
Bell nonlocality without input settings, .g., in the triangle network, has been perceived to be particularly fragile, with low robustness to noise in physical implementations. Here, we show to the contrary that nonlocality based on N00N states already for $N=2$ has an exceptionally high robustness t… [Phys. Rev. Lett. 135, 160803] Published Tue Oct 14, 2025
