Quantum algorithms sort of operate on all superposed states at the same time.

This is not entirely correct.

Also, from your linked article:

I will now introduce the Deutsch Oracle algorithm, one of the first examples of a quantum algorithm that is exponentially faster than its classical counterpart on the size of the input.

This is not entirely correct either.

Hi, thanks for going through my blog post!

Could you elaborate on why you believe my writings are imprecise? I read the link you provided, but couldn't find any divergence with its text though.

Here's the line of thought behind my statements if it's not clear to you:

1) Until a measure is made leading to the collapse of the quantum state qubits remain (possibly) in a superposed state. When a quantum gate is applied to these qubits it affects all superposed states (from a linear algebra point of view).

2) I took this statement from Wikipedia [1], forgot to link the source in the article: Simon, Daniel (November 1994). "On the Power of Quantum Computation". 94 Proceedings of the 35th Annual Symposium on Foundations of Computer Science: 116–123.
