At the end of part 3 of this series, after getting severely tangled in the weeds of trying to understand entanglement (let alone teleportation) I ended with a joke saying I would be back for part 4 to explain how it all REALLY works.

Well, guess what! With even more surprise than you (though probably less scepticism), I am back with a very different presentation of quantum computing that does away with matrices and kets and replaces them with lovely little diagrams. What’s more, teleportation actually makes sense in these diagrams!

Even better news is that you won’t have to…


So you’ve teleported some qubits, now you must want to know — how?

Welcome back. This is part 3 of my series on quantum teleportation. In the first part, I introduced the foundational theory and notation for quantum computing. In the second part, I showed how to do it in real life (with some minor caveats) on a real quantum computer. Why not check them out if you haven’t already (for the sake of The Algorithm if not your curiosity).

Finally, in this part, I’m going to give you my very unqualified thoughts about what sort of crazy universe could…


With the theory done, we can now teleport a real qubit on a real device!

This is the second part of my series on quantum teleportation. The first part covers the basics of quantum computing and ends with a description of the circuit which we will be using in this article. In this part, we will pick up there and learn how to code it using a python package qiskit. Along the way, you’ll also learn a bit about some of the current challenges in quantum computing. …


Ever wish you could send information instantaneously across the universe perfectly securely? Well that's lucky — you’ve come to the right place.

This is part 1 of my 3-part series on quantum teleportation. In this part, you are going to be led through a wild and woolly path from the very the basics of quantum computing up to a description of the truly mind-blowing quantum teleportation protocol. Don’t worry if you can’t understand it completely, not a brain in the world does! Nevertheless, if you feel stuck at any point please feel free to ask questions in the comments.
