Famous Double-Slit Experiment Holds Up When Stripped To Its Quantum Essentials


Longtime Slashdot reader ndsurvivor shares a report from MIT: 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 light. They also happen to confirm that A...

Today, with the formulation of quantum mechanics, the double-slit experiment is now known for its surprisingly simple demonstration of a head-scratching reality: that light exists as both a particle and a wave. Now, MIT physicists have performed the most "idealized" version of the double-slit experiment to date. The researchers thus confirmed the predictions of quantum theory: The more information was obtained about the path (i.e. the particle nature) of light, the lower the visibility of the interference pattern was.
