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.

I'm not an expert in quantum holography, but as far as I know, it's a kind of fault tolerance framework. If so, then the most fundamental layer of this technical route would still be qubits, only the requirements for scale or fidelity are looser. Actually I also believe in Fault Tolerant quantum computing, and many great works have been done. But the sad story is our lab chose a route that is not fault-tolerance friendly (at least for now), so I'm a little nervous. Anyway I hope the day will come soon.

The “qubit” or “spin disposition” is the only discretely identifiable information layer we may technologically access. Multidimensional analog “images” may be stored and retrieved (by passive differential) in this space, without collapsing entanglement. Hyperdimensionality means there are dimensionalities folded into the domain like origami. All of this may someday be accessed, and I’m pretty sure this is happening in our very own brains.
