Quantum computing is a way of using the properties of quantum mechanics, which is the physics that describes how very small things behave, to perform calculations that are faster than is possible using classical computers.

Classical computers use bits to store information and perform calculations. A bit is a unit of information that can be either a 0 or a 1. Quantum computers use quantum bits, or qubits, to store information. Qubits can represent both a 0 and a 1 at the same time, which allows quantum computers to perform many calculations at once.

Because of this, quantum computers have the potential to solve certain problems much faster than classical computers. For example, they could be used to break encryption codes that would take a classical computer many years to crack. However, quantum computers are still very experimental and there are many challenges to overcome before they can be used for practical applications.

ChatGPT is like the Midjourney of language AIs. It can spit out some pretty impressive stuff, but it all kinda sounds the same once you learn to recognize it.

Yeah, it's a great launch point, but definitely formulaic. It lacks personality but does a lot of the information gathering and structuring. This just happened to be an example question it uses that was one of the best explanations I'd seen.

You can tell because the second paragraph sucks lol

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.
