The mystery

Quantum mechanics is one of the most mysterious fields of science. You may have heard that particles can exist in two places at once and that the mere act of observation collapses the wave function, altering—or even creating—reality. Allegedly, this collapse is a source of true randomness; a fundamental roll of dice

Entanglement:

Can information travels faster than the speed of light with entanglement? Imagine placing a blue and a red in two same looking box. We ship one of them at random to Mars. Whenever one box is open, we instantly know the color of the other ball, even if kilometers away.

Many world?:

If you're puzzled by these mysteries, you're on the right website. Before buying into the hype, we suggest taking a step back and considering how these claims mesh with the mathematical formalism and experimental observations. Don’t worry, we will walk you through the mathematics of quantum theory, and present you with detailed and clear experiments; some of which will be hands-on as you may want to try out our interactive simulators.
