Physicists have demonstrated they can move atoms with incredible reliability, both in 2D and in 3D – and to really show it off, they created the world's smallest cat video: a movie of 2024 rubidium atoms showing the famous quantum cat thought experiment first suggested by Erwin Schrodinger. The approach employs a machine learning algorithm and optical traps that can rearrange thousands of atoms in just 60 milliseconds. The movie, which can be watched below, is slowed down by about 33 times. The rest of this article is behind a paywall. Please sign in or subscribe to access the full content.

The quantum cat is probably the most famous of all quantum thought experiments, and aims at linking the macroscopic world we inhabit to the quantum. Imagine you have a vial of poison in a box that is
