Reply to comment by digitalindigo in can someone explain the difference between quantum computing and classic computing in simpler words? how can quantum computing benefit us from a consumer perspective? by village_aapiser

Do we yet understand how a quibit can represent 0 and 1? Or is that still undiscovered/still being studied? I'd appreciate the insight!

A quibit is (essentially) a probability of being a zero or a one. Or at least sort of. quantum mechanics has this thing called probability amplitudes which are complex numbers, not a regular percentage, but when you square those you get normal probability

so because these are weird, you don't just have one degree of freedom that you could just represent with normal numbers probability. Each Qubit can be represented by a position on a "bloch sphere".

So you can think about each gate doing some math between two those qubits.

At the end of the whole thing though, you end up with a series of classical bits

I think it's more that the programming is able to use each bit of data as an 'if this, than that' context, much like the human brain can but without the biological limits. It requires a ton of energy but allows it to run simultaneous possibilities against each other without needing to reach entire conclusions sequentially.
