It underpins the whole theory of quantum mechanics, but does it exist? For nearly a century physicists have argued about whether the wave function is a real part of the world or just a mathematical tool. Now, the first experiment in years to draw a line in ...

The precise imaging of many-body systems, which are comprised of many interacting particles, can help to validate theoretical models and better understand how individual particles in these systems influence each other.

Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has some strange implications for the theory of quantum mechanics.

A new version of quantum theory sweeps away the bizarre paradoxes of the microscopic world. The cost? Quantum information exists only in your imagination Flawlessly accounting for the behavior of matter on scales from the subatomic to the astronomical ...
