The future of Photonics: Why light-based qubits might win

Unlike superconducting qubits, photons don't need a dilution refrigerator. They can travel through room-temperature fiber optics. The main challenge? Interaction. How do we make two photons talk to each other reliably?

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

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?
