Who's in Charge?

Does free will exist, or is it merely an illusion? Are we the authors of our own actions? The thinkers of our own thoughts? Or are we mere witnesses of our lives? Prisoners of the strict laws of cause and effect, with no room for freedom of choice? Press the yellow button and find it out!

Workshop on Entanglement

Initially, the concept of entanglement has been coined by Schrödinger to describe a fundamental property of a composed, physical system whose parts have interacted in their common past (Schrödinger, 1935): "When two systems, of which we know the states by their respective representatives, enter into temporary physical interaction due to known forces between them, and when after a time of…

Beam me up, Scotty! How to build a quantum teleportation device

Imagine a world where, at the flick of a switch, you could beam yourself across space to whatever destination you'd like, without having to spend hours on the bus, stuck in traffic, with a group of noisy school kids. All you’d need is a teleportation device. But will science fiction ever become science fact? Press the yellow button, and check it out!

Schrödinger's Cat and the Measurement Problem

In 1935, Erwin Schrödinger devised a horrifying thought experiment about a cat in a box. The appalling results of his experiment went to the crux of the most severe problem of quantum mechanics — the infamous measurement problem. Much of the philosophical discussion about quantum mechanics still revolves around this problem and how one might go about solving it. Can't resist taking a sneak peek at what's going on inside the box? Press the yellow button, and continue reading!
