The Quantum Internet

Season 5 Episode 26

The world is widely regarded as being well and truly into the digital age, also called the information age. However, it’s one thing to design a protocol, it’s something else entirely to build a system to support it. To understand what needs to be done we need to get to the foundations of quantum mechanics - we need to talk about quantum information theory.
