Now that you’ve seen the possibilities the quantum internet has to offer, you can ask the question: So what do we actually need to build a quantum internet? In this video, David will explain the elements needed to construct an internet, and how we can realize those elements.

Main takeaways

• A quantum network consists of three main building blocks.
• The quantum channel is the physical medium that enables to transmit quantum bits. Two types of channels are commonly used: free-space channels and fiber-optical channels.
• Quantum repeaters are fundamental to faithfully connect nodes distant from each other.
• We call the end node (or quantum node) the device in charge of performing the necessary tasks of quantum information processing.
