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!
