From your morning coffee to the road leading to your office and all other things and people you experience in your everyday life are all part of the classical world. This world is governed by the ...

Students learning quantum mechanics are taught the Schrodinger equation and how to solve it to obtain a wave function. But a crucial step is skipped because it has puzzled scientists since the ...

Quantum theory is one of the great achievements of 20th century science, yet physicists have struggled to find a clear boundary between our everyday world and what Albert Einstein called the "spooky" ...

For the first time, researchers have produced experimental evidence that classical chaos occurs in the quantum world. Chaotic behavior is the rule, not the exception, in the world we experience ...

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 ...

A classical beam of light that would be expected to obey Bell's Inequality can fail this test in the lab, if the beam is properly prepared to have a particular feature: entanglement. Quantum theory is ...
