In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.Check out the new Space Time Merch Store!https://pbsspacetime.com/Support Space Time on Patreonhttps://www.patreon.com/pbsspacetimeNeed a Black Hole Refresherhttps://youtu.be/vNaEBbFbvcY#cryptography #quantumcomputing #spacetimeHosted by Matt O'DowdWritten by Graeme Gossel and Matt O'DowdGraphics by Leonardo WilleDirected by Andrew KornhaberProduced By: Kornhaber BrownQuantum theory may seem like an obscure subject of questionable relevance to the average person. But in fact much of our technological world depends on our understanding of the quantum properties of the subatomic universe. And soon, perhaps very soon, we’ll be interacting with the weirdness of quantum mechanics even more directly – with the coming of quantum computing and the quantum internet. Quantum computing is a topic that’s that has been well covered, so we’re going to be talking about the quantum internet. Specifically quantum cryptography and quantum key distribution – the foundations of the prospective quantum internet. We may come back to quantum computer in detail – but for now let me show you why their advent will demand a quantum internet.
