A basic principle of quantum mechanics has been reaffirmed. Stop the presses. (Or start the tweeting.) It’s no surprise, really, for quantum physics to withstand another assault. It would have been ...

This week marks the centenary of the French physicist Louis de Broglie's doctoral thesis, which later earned him a Nobel prize for "his discovery of the wave nature of electrons." This discovery ...

The classic signature of wave-particle duality in quantum particles is the wave-like interference pattern that is produced when a beam of particles passes through a ‘double-slit’. Researchers have ...

What is the simplest, most fundamental clock? Physicists have shown that a single atom is sufficient to measure time using its high-frequency matter wave. Conversely, the frequency of matter can be ...

In October 1927, some of the greatest minds in physics gathered for the Fifth Solvay International Conference to debate the troubling implications of the then-nascent theory of quantum mechanics. A ...
