with error correction, qc is entirely distinct from analog computing. that is what makes it even remotely viable, theoretically.

I'm using the term "analog computing" to mean using non-digital (or even digital but in a nonstandard way). A quantum processor is not digital as each qubit has an uncountable number of states. A quantum computer would likely have a classical (digital) part to measure the quantum processor's registers, which are a bunch of "analog" states. And even if one wants to use terminology in a way that qc isn't analog, it would still objectively share many qualities with "normal" analog computing (basically all of its differentiators against classical compute).

Then again, I should probably also ask what you mean by "analog computing", and why you think quantum error correction would not allow qc to be classified as analog.

For context, I did research on crafting a high-fidelity (error-correcting) quantum gate (successfully).
