Quantum physicist here: just to correct the mistaken claims in this, interference is definitely a feature of quantum computing, and not a bug.

Interference is also NOT why there are are no error corrected quantum computers. The reason there are no error corrected quantum computers is because we need way (way way) many more physical qubits, and they would need to be of better quality (less decoherence).

I don’t think it’s a mistaken claim so much as a misused term-of-art by conflating it with its layman meaning. If you replace “interference” with “noise”, what’s being said makes sense.

However, the second bit you said is true, even after correcting the term.

They seem to know about decoherence, and in a later post associate interference with probabilities, so I don't think that was the issue. Maybe a typo?
