Experiment
Physicists at the University of Vienna have conducted an experiment demonstrating a superposition of different temporal orders in quantum events, using entangled photons and a Bell inequality equivalent. The results deviate significantly from classical expectations, suggesting indefinite causal order is a fundamental quantum feature. However, several experimental loopholes remain open.

A century-old thought experiment proposed by Albert Einstein to challenge Niels Bohr's ideas on quantum mechanics has been realized in a real-world test. Researchers led by Chao-Yang Lu at the University of Science and Technology of China used modern tools to confirm Bohr's principle of complementarity. The findings show that light exhibits both wave and particle properties, but not simultaneously in a clear way.
