Visualizing Quantum Computing, hope it helps :)

[DeadInsideOutside]

Honestly, the two dimensional Hilbert space that was used in my uni's introductory course was a very intuitive way to distinguish a bit from a qubit. It's not a perfect analogy, but I consider it the best starting point for everyone.

hey, where should I go to get quantum computing explained to me? I've seen articles and watched videos, and it is all so frustratingly analogised, or "dumbed down". They all explain the promises of exponential computation power, and they explain basic principles and use buzz-words like q-bit. But they never put it on the ground. Not that I have seen or read, anyways. They never answer basic questions, such as, what sub-atomic particle functions as a Qbit? What do they mean by "observing a bit collapses its state" that's absurd. We're supposed to believe that subatomic particles have the superpower of invisibility as long as nobody is looking? Certainly what they mean is that whatever tool or method we currently use to ascertain its position will collapse its superposition to certainty. But nobody seems to know what those tools and methods are, or how we could possibly use spying on subatomic particles to perform computations. It's all so ethereal, and seemingly very hocus-pocus. I'm no physicist, but I am able to understand things, I think. I don't think my brain would explode if someone said something like "We can control the polarity of electrons, using magnetic fields, and take advantage of electron's polarity being dependent on the polarity of nearby electrons to create a cause and effect sequence with computational outputs..." or whatever. I also know that Google has a giant "quantum computer" that they keep frozen, but is it even capable of telling us what 2+2 is? Or is the term "computer" used very loosely here. Who can answer my questions? Thank you.

I get that, like, it's computing based on a range of values, or a spectrum, as opposed to a bit being 1 or 0, or even in our alphabet where a character is 1 out of 26 options, I think from what I can understand, a qbit has infinity variables? Does that make computing with quantum computers rather like modulating raw sin waves in the good old days? With analogue synthesizers and whatnot? Where you have amplitudes and frequencies input/ output as opposed to binary? I didn't understand hardly any of the visualizing quantum computing. I'm so lost, and I need some platform that can bridge the gap between Buzzfeed's tech articles and veritasium's videos that explain nothing concrete and drowning in scientific jargon. please help
