... Everyday experiences follow clear, sensible rules. For example, if you find a letter in your mailbox, someone obviously delivered it there. This simple logic—called local realism—assumes objects exist clearly and events happen predictably, influenced solely by immediate surroundings. ...
But quantum mechanics rejects such straightforward reasoning. In this bizarre quantum world, particles can exist in multiple states simultaneously until someone observes them. The GHZ paradox illustrates how this idea mathematically breaks classical rules, even suggesting absurd outcomes like one equaling negative one. ...
Photons—the tiny particles making up light—were controlled in ways requiring 37 separate points of reference. Handling quantum states at this scale allowed researchers to deeply explore how quantum mechanics diverges from common sense and classical physics. ...
One of the key takeaways from the experiment is that quantum mechanics does not conform to classical expectations. By creating a GHZ-type paradox in 37 dimensions, the researchers demonstrated a breakdown of local realism in ways previously unexplored. ...
The research team mathematically confirmed that their experiment achieved the strongest recorded manifestation of quantum nonlocality. ...
