Quantum computing often grabs the headlines. The word "quantum" itself is intriguing enough, but what exactly is quantum computing?

Elliott Lieb has been awarded the 2022 Gauss Prize for outstanding contributions to physics, chemistry, and pure mathematics.
Natalia Berloff explains how quantum particles, that are both light and matter, help solve infamous NP hard problems.

The "quantum mechanic" talks about how quantum computers might impact society and the limits of measurement.

This year's Nobel Prize for Physics brings together the physics of materials with one of our favourite areas of maths – topology. In this final article in a series, we asked Fiona Burnell to explain the maths behind the work, and how it may help lead to quicker and smaller electronics, and even the elusive quantum computer.
