The validity of the superposition principle and of Born’s rule are well-accepted tenants of quantum mechanics. Surprisingly, it has been predicted that the intensity pattern formed in a three-slit ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

Today (April 14) marks 2025's World Quantum Day, an international celebration held to promote public understanding of quantum science. The date, 4/14, was chosen because 4.14 represents the first ...

At the quantum boundary This experiment at the University of Vienna proves that objects as big as molecules can interfere. (Image: Robin Riegler) Ever since quantum theory was developed during the ...
