qc-002Established result
Superconducting circuits, trapped ions, neutral atoms, photonics, and semiconductor spins are distinct hardware approaches with different engineering trade-offs.
They differ in how qubits are made, controlled, connected, and measured, so raw qubit counts alone are not comparable performance measures.
