(Forbes.com) A quantum network isn’t the quantum internet. For that to happen, it would take something else for any two users connected to a wide network to be able to store and exchange qubits. We’re a long way from having that, though: There still aren’t networks connecting quantum processors (which will turn those networks into a quantum internet), nor are there quantum repeaters outside a lab A quantum network implies the interconnection of several nodes (devices or computers) that exchange quantum information instead of classic data. So, the second thing needed to understand the quantum internet is knowing what quantum information actually is.
Researchers at the Delft University of Technology have outlined six steps necessary before we get to a quantum internet:
1. Trusted-node network
2. Prepare and measure
3. Entanglement distribution networks
4. Quantum memory networks
5. and 6. Quantum computing networks
