An edX course co-taught by Caltech and TU Delft covering quantum cryptography, including quantum key distribution and the quantum principles behind secure communication. It is described as more advanced than introductory cryptography courses.
Commenters call it a highly recommended free course for learning about quantum cryptography and the quantum internet, and note it goes beyond introductory cryptography material.

That research quantum network has a different purpose. Quantum key distribution (QKD) as mentioned in the article has been commercially available for a number of years now (for example by ID Quantique [1]). These products rely on having a direct connection, i.e. a single fibre line without repeaters or other ‘interruptions’. This limits their range to about 100km (20dB attenuation).
The research network in The Netherlands is more ambitious than that. The researchers’ goal is to build a true quantum internet, with ‘quantum repeaters’ that allow connections over longer distances [2]. These quantum repeaters work on the principe of quantum entanglement generation and purification to achieve quantum teleportation of qubits to allow end to end communication [3].
If you’re interested in learning more about this, I can highly recommend the free edX course by TU Delft and Caltech on quantum cryptography [4].

This is currently on edx. Its more advanced that the courses mentioned here. I do not know what edx will do after the course ends, but if you want it you can get it while it ss still available.
