This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...

An international research team led by physicists from Collaborative Research Centre 1238, 'Control and Dynamics of Quantum Materials' at the University of Cologne has implemented a new variant of the ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

BERKELEY, CA -- The big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is ...

Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists a single, concrete reality. In 2005, a ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is still the star of that show. A new, ultra-clean version of this classic test ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...
