A paradox at the heart of quantum physics has been tested in an extraordinary fashion, pushing the boundaries of human intuition beyond breaking point by measuring a pulse of light in 37 dimensions. Led by scientists from the University of Science and Technology of China, a team of researchers developed a method of testing a type of Greenberger-Horne-Zeilinger (GHZ) paradox according to strict criteria using a fiber-based photonic processor. Their findings clarify how quantum weirdness operates on a fundamental level, potentially informing future applications in quantum technology. Not to mention reaffirming just how useless our brains are at understanding the…
