SUMMARY
The recent experiment conducted by Glasgow student Jacquie Romero, which involved firing an ultraviolet laser into an optical crystal to produce entangled infrared photons, has significant implications for the de Broglie-Bohm theory and nonlocal realism. The results, published in the paper "Violation of Leggett inequalities in orbital angular momentum subspaces," demonstrate that a large class of nonlocal realism models is ruled out, challenging the compatibility of these theories with quantum mechanics. Experts like Simon Gröblacher emphasize that while realism is challenged, nonlocal non-realism models may still be viable, indicating that the de Broglie-Bohm theory may not be entirely refuted.
