Reply to comment by matpompili in Experimental demonstration of entanglement delivery using a quantum network stack by matpompili

This is great work! Congrats on the publication and looking forward to seeing this network stack used for future technologies!

My question is this: how easy/difficult would it be to use this stack to build networks with other types of quantum hardware (atoms, superconducting circuits, etc)? My naive feeling is that most of the innovation is in the physical layer, which would presumably need to completely rebuilt for a different type of qubit?

Thanks! I would say this was just as much innovation at the physical layer (running quantum network operations in real time) than at the link layer and above (implementing for the first time an entanglement distribution service, keeping track of entangled qubits and states delivered, assigning them to different quantum applications and so on).

The link layer we implemented is completely agnostic to the physical layer implementation, so the job for the developers on a different platform would be to be able to receive a set of instructions from the link layer and to execute the required operation on the hardware and reply with one of the expected outcomes, you can see a list of commands/replies here
Then you can run the exact same Python-based apps we ran on our diamond devices on other platforms, with no other changes (the only caveat is that if the platform does not support some quantum gates, the link layer needs to be made aware of that, such that it can convert the application to use a different set of gates)
