How to read Randomized Benchmarking (RB) Results

The decay curve gives the average gate error. But how do we distinguish between coherent and incoherent noise from a standard RB plot?

Scaling this beyond 100 qubits requires a serious rethink of the coaxial routing. Have you considered using monolithic 3D integration with through-silicon vias?

Reliable scaling is the only metric that matters now. If the interconnect bandwidth doesn't improve, these T2 times are just academic benchmarks.

Wait, the cross-talk numbers in this comparison look highly optimistic. Was this measured under simultaneous gate operations or in isolation?
