Any evidence that these are quantum coherent devices? In seems like the only reference in the paper is that "future improvements" will allow entanglement generation. I don't think the use of "closes in" in the HN title would be appropriate if these are such early stage devices that they can't even put a number on the coherence time yet.

It may be that the use of photons gives long coherence in these devices as compared to other types of potential qubits, but then you still have to ask about (coherence time) / (gate time).
