Leading experimentalists have provided lectures on the up-to-date experimental evidence confirming these paradoxical features of the quantum world, such as quantum non-locality (demonstrated ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum ...

Quantum Entanglement is the biggest mystery of science that could upend life as we know it, writes Satyen K. Bordoloi.

How do you calculate infinite quantum outcomes? Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

A world-renowned chemical theorist will visit the West Lafayette campus Sept. 23-24 to initiate a new lecture series created by the Department of Chemistry's Theory Group. Henry F. Schaefer III, ...

Visualization of a quantum field theory calculation showing virtual particles in the quantum vacuum. (Specifically, for the strong interactions.) Even in empty space, this vacuum energy is non-zero.

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory ...
