If you look at Google and IBM superconducting quantum processors, they don't use this base 2 for quantum processors (Google's paper on quantum supremacy for instance had 53 qubits and the new IBM one claim to have is 127).
It might be due to this architecture with atoms instead of superconducting circuits, but on theory there is no need for base 2.
