The qubit is a dead end.

The future of quantum computing (which has not yet been invented or explored) is quantum holography.

This will be the mathematicians’ sweetest dreams. Manipulate quantum holographic memory space through constructive and destructive interference, multidimensional transformations, translations between surface areas, and the like. This will more closely resemble analog computing than digital.

The engineering problems today are relevant steps yet any programmatic exercises relying on qubits are useless. Spin disposition is not the most information dense aspect of the quantum domain.

The day will come, only not any time soon.
