**A tool for precisely modelling real-world quantum devices**

Quantum theory governs the behaviour of fundamental particles, atoms, and molecules, i.e., of nature at the smallest scale. Intriguingly and counter-intuitively, quantum systems can simultaneously ‘be’ in combinations of physical states that are mutually incompatible according to classical physics. Examples we can name are the... click to read more

**Magic Squares: A children’s puzzle meets quantum physics**

Magic squares have fascinated people for centuries. A magic square is a grid of numbers such that every column and row sum up to the same number, called the “magic constant”. For example, a magic square can be seen on the façade of the Sagrada... click to read more

**Silencing a quantum drum**

To a classical physicist, there is no fundamental limit to how well you can measure something. A classical object, for example, always exists in a well-defined position; if you want to know that position with better accuracy, you simply build a better microscope. The story... click to read more
