SUMMARY
The dimensionality of vector spaces for different quantum states is not the same, as demonstrated in the particle in a box problem. The energy eigenbasis is countably infinite, while the position eigenbasis is uncountably infinite. This discrepancy arises because the eigenstates of the position operator (X) exist in a larger topological vector space compared to the eigenstates of the Hamiltonian operator (H). Consequently, the spectral equations for X and H do not yield solutions within the same vector space.
