What is a Quantum Internet?

A quantum internet is a radically new technology that allows us to solve tasks that are impossible to accomplish on the classical internet.

Did you know that having only one qubit might be quite enough to build a fully functional quantum internet with many applications? Professor Stephanie Wehner (QuTech) introduces the building blocks of a quantum network and the power of entanglement. Which elements are essential to distribute entanglement in such types of networks successfully? 

Prerequisite knowledge

 

 

Further thinking

If you wanted to build a quantum network and distribute entanglement:

  1. What would you use to transfer the qubits?
  2. What would your end-nodes look like?
  3. Why is the required repeater different from the classical repeater?
