Quatum Computing Questions

Sup /comp/, I have a question that may sound stupid. I've been reading up on quantum computers. I understand that a bit is always in one of two states. Now a qubit, a bit in quantum computing, can be in either state, or a superposition of both.

Now, a qubit can be in either state at the same time, but nevertheless is only two. So how is this any more advanced than a contemporary bit?

I think I have a decent understanding of a "superposition," which is all the possible states, in a qubit's case, 0 or 1. But it's still only two!

Is it that a qubit can be more than those, by which i mean, a qubit can be read by a quantum computer to be a line of multiple bits? This is stupid and makes no sense, where is the date stored? What is the limit, if everything can be stored on a single qubit simply because it the qubit can be everything at once?

I'm sorry if this is a stupid question, but I'm hungry for knowledge. Pic unrelated.

Do you understand standard computer architectures at all? You know how they talk about 16/32/64-bit computing, that's the size of the registers, data bus, etc. For a quantum computer to be useful for real world applications it will need multiple qubits in the same way normal computers need multiple bits.

The speed advantage of a quantum computer comes from doing away with iteration. Say you're try to break a 32 bit encryption, brute forcing it will require up to 4 billion (2^32) iterations, whereas if you had a 32 qubit computer you could test all the keys simultaneously.

Pic unrelated.

you were initially correct though you need not have sought permission
