Quantum Lego: Building with single atoms

What if you could build a machine atom by atom? At our interactive booth, discover how researchers use light to trap, move and arrange individual atoms with extraordinary precision. These techniques are helping to create new quantum technologies and are enabling powerful quantum computers and quantum simulators.

See a real experimental setup in action and learn how tightly focused laser beams act like optical tweezers, holding atoms in place and arranging them into programmable patterns. Find out how scientists can control individual atoms and use them to store and process quantum information.

Want to try it yourself? Explore hands-on demonstrations that reveal how light can be shaped and controlled. Observe how optical devices change the shape of light in a predictable and programmable way. Then take on a challenge inspired by real quantum research: develop your own strategy for moving “atoms” from a random pattern into target positions. Can you find an optimal solution with the minimal steps?

With real laboratory equipment, visual demonstrations, and interactive exhibits, our booth offers a glimpse into the fascinating world of quantum research, where light is used to control individual atoms and assemble quantum machines capable of performing tasks beyond the reach of classical machines.
