A team of Chinese researchers has tested a type of paradox at the heart of quantum physics by measuring light in 37 dimensions. They used a fiber-based photonic processor to test the Greenberger-Horne-Zeilinger (GHZ) paradox, which challenges local realism and our understanding of reality.
The experiment aimed to find the most extreme case of non-locality using just three contexts, but their findings reveal that even with this limited information, our expectations of local realism can be thrown into doubt. To resolve this, the researchers added 33 extra dimensions, each representing a different spatial dimension, and found that only 37 states could solve the relationships between the three contexts.
The implications of this research are far-reaching, as it challenges our classical understanding of reality and raises questions about the nature of space, time, and causality. While the study’s findings may seem absurd at first, they can lead to deeper explorations of reality’s foundations and potentially inform future applications in quantum technology.
