Example of a quantum algorithm better than its classical counterpart which involves only $1$ qubit?

I was reading over the proof of the Deutsch-Jozsa algorithm, which in its simplest case, involves at least 2 qubits. Is there an example of a quantum algorithm that is better than it's classical ...

Is "classical information" the same as "Shannon information"?

does Shannon meet Feynman? Bits underlie classical information measurements in information theory, while qubits underlie quantum information measurements in, what I can only assume to be called, ...

Is there any real world problem where I can see quantum computing being better than classical computing?

Is there any paper or piece of code showing, on a REAL quantum computer, that a specific real world problem (possibly related to computer science, machine learning or finance and possibly NOT related ...

How to copy value from classical register to quantum register?

I have 1-qubit of quantum register and 2-bit of classical register. I have this simple algorithm: First, I'm doing simple process for q[0] with NOT. Second, I want ...
