    You’re talking the old CPU designs, not the current ones fighting tunneling effects or the work-in-progress photonics & 2D hybrids.

      No, I am not sure that I am.

      Photonic processing, whilst very cool and super exciting, is not a quantum thing… Maxwells equations are exceedingly classical.

      As for the rest it’s transistor design optimisation, enabled predominantly by materials science and ASMLs EUV tech I guess:), but still exploits the same underlying ‘quantum 1.0’ physics.

      Spintronics (which could be what you mean by 2D) is for sure in-between (1.5?), leveraging spin for low energy compute.

      Quantum 2.0 is systems exploiting entanglement and superposition - i.e. qubits in a QPU (and a few quantum sensing applications).
