= Superconducting qubits are bad because of fabrication variation
Atom-based <qubits> like <trapped ion quantum computers> have parameters fixed by the laws of physics.
However superconducting qubits have a limit on how precise their parameters can be set based on how well we can fabricate devices. This may require per-device characterisation.
