#4 : Quantum computers

Quantum computers

How do you build a quantum computer and what can you do with it?

A little qubit more.

In the previous track you've learned about qubits (quantum bits). According to Julia there are many ways you can build them.

And speaking of ultracold atoms...

That is how they are building a quantum computer at the Technical University of Eindhoven.

There we meet Servaas Kokkelmans.

He is the director of the Eindhoven Center for Quantum Materials and Technology.

How do you cool down those atoms?

Servaas shines his light on this.

Not just any atom.

When Servaas speaks of atoms, he means a special type: Rydberg atoms. If you shoot these with a laser, you move the electron (the green dot) to the outside.

Atoms that work together.

Researcher Denise Ahmed-Braun explains how they influence each other and work together.

You’ve guessed it…

The more qubits, the more you can compute with such a computer.

How does Denise deal with this challenge?

In summary.

Thanks to our visit to Eindhoven we know a lot more:

That you can use atoms as qubits
That you can place atoms on a lattice by using light
That they can transmit information that way
That there are still challenges with error correction
That this makes a hybrid computer more plausible
