The teleportation kata covers quantum teleportation - a protocol which allows to communicate a quantum state using only classical communication and previously shared quantum entanglement.
You can run the Teleportation kata as a Jupyter Notebook!
- Another description can be found in the Wikipedia article.
- An interactive demonstration can be found on the Wolfram Demonstrations Project.
The principle of deferred measurement, applied to teleportation protocol, is described in Nielsen & Chuang, section 4.4 (pp. 185-187).
