Doesn't current quantum teleportation require optical connectivity because the state transfers along photons?
The abstract says
>Here, we report the demonstration of chip-to-chip quantum teleportation and genuine multipartite entanglement, the core functionalities in quantum technologies, on silicon-photonic circuitry
So while there may not necessarily be a phsyical connection this does require line-of-sight by my read, and "silicon-photonic circuitry" sounds like this is all on one physical board.
I guess I don't understand how this is "two different chips" as the article claims. Did they use two photomasks? Baby steps, I suppose.
