Rigetti Ankaa-2 vs IBM Condor: Real-world CLOPS comparison

We just finished a benchmarking run comparing the gate fidelity and CLOPS (Circuit Layer Operations Per Second) on the latest architectures. While IBM has a lead in raw qubit count, Rigetti's tiling architecture is showing interesting scaling for certain Variational Algorithms. Has anyone else pulled the latest Qiskit-Experiments data for these?

I've benchmarked Ankaa-2 as well. The crosstalk mitigation is a huge step up from Aspen-M3. Did you use the new 'readout-error-mitigation' package?

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

Actually, IBM's Condor has better connectivity for 100+ qubit circuits. Tiling is great until you need a global swap.

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

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