@kongakong Do we really believe this?

Does anyone know of a good explanation of quantum mechanics or theory put in a way a layman can understand?

Every one I've ever seen is like "it's fucking weird don't worry about it". Followed by "we're building a computer based on it". Well silicon bits is fucking weird too but it was explained to me and I understood it. Why can't I find a good explanation of quantum and quantum computing?

squid010,

@Tekchip I liked Helgoland. You can also, in all seriousness, ask chatgpt with the right prompts to teach you

@squid010 this one yeah? https://a.co/d/gTmu1av

Thank you for the recommendation!

No comment on the rest of the article, but I'm extremely sad to see the New York Times repeating the same two-places-at-once, Schrödinger's cat, and quantum parallelism nonsense that is so unfortunately common in .

One last note, but before invoking Schrödinger's cat, it's helpful to read what Schrödinger himself had to say.

Historically, the idea of interpreting the Schrödinger equation literally was quite controversial — something he himself rejected. It was largely seen as an effective model for some other theory that was more palatable to classical intuition, but we know from things like Bell's theorem that we actually have to take quantum theory literally to make sense of the world.

Bell's theorem is almost sixty years old now, so we've had plenty of time to come up with new ways of explaining and understanding quantum mechanics that don't depend on appeals to classical mechanics — we don't need to carry Schrödinger's century-old misunderstandings along with us now.

Steve Gibson’s explanation of the quantum computing breakthrough

I’ve not really bothered to follow the quantum computing hype until it was going to become any sort of reality in our future. The issue has been mostly around its instability and required error correction.
