One of the most exciting applications of a quantum network is in combination with quantum computation. A bottleneck of quantum processors is scalability, but what if we could just keep the processors at a reduced and realistic number of qubits and enhance the connection between them, configuring a multi-node quantum computer?
Can you think of other protocols or synchronization functionalities that could have a solution in quantum networks that are impossible to solve using a classical internet?
Imagine there are four robots on the mountain, all of them well-behaving. Can you come up with how they will agree on the attack? Can you write down the quantum state that needs to be distributed?
