Particles of light helped test a quantum paradox Arlume/Alamy
Particles of light that effectively exist in 37 dimensions at once have been used to test an extreme version of a quantum paradox.
鈥淭his experiment shows that quantum physics is more nonclassical than many of us thought. It could be [that] 100 years after its discovery, we are still only seeing the tip of the iceberg,鈥 says at the Technical University of Denmark.
He and his colleagues focused on the Greenberger-Horne-Zeilinger (GHZ) paradox, which shows quantum particles can…
