Quantum Key Distribution in QNE

In this video, we will take a look at one of the most promising applications of a quantum network: the quantum key distribution (QKD) protocol. After explaining the goal of QKD, the steps involved in the protocol are discussed, and we will see how to run the protocol in the QNE environment.

Main takeaways

• Introduces quantum network protocol through QKD protocol; the learner will understand how a quantum network protocol is written and executed.
• Introduction to running a quantum network protocol on the QNE platform.
• Introduces how the performance of quantum network protocol is assessed - in this case introducing quantum bit error rate.

Further thinking

Is generating entanglement necessary to perform QKD?
