Did any of u understood any of that

so quantum computers are based on "probable answers" and the quantity determines which one is probably correct? Can one attach a value 0 or 1 to a Qbit so that when it is measured it collapses predictably? I'm pretty sure this is a stupidly inaccurate question but, if anyone with the knowledge can share a hint I'd appreciate.

Heres my question though; if photons are in a state of being either a 0 or 1, how do you keep it from changing? 0 or 1 with the standard electrons is either on or off but photons' 0 or 1 is based on its polar direction that is constantly changing? How is that control?

Quantum computers are fascinating, I am really looking forward to seeing what will be done with them; especially curious if they will ever be reasonably mass produced some day for consumers.

It'S not possible for me yet how can i defined my actual data that i want it means you need another regular computer to defined your data, an how can the quantum will respond for that 🙄

Okay so I get this can be really powerful but tell me how to practically save and read data if a qubit is in both states at once and is only definitive when observed... If you want to save a string saying "Hi" (01001000 01101001) into qubits but next time you read it it suddenly says "No" (01001110 01101111) then how is it useful to use quantum computers?

This video did a better job at explaining transistor functioning that some of my high school teachers. Thanks.
It's the conjuncture of the elephant in the dark room... Maybe we're mesuring the balls, but yet we say they are 2 super imposed shafts! New minds needs to redefine the parameters of the epitemological state of science because I have not a clue of what I am talking about; weed has just been legalized here in Canada and I'm high as a kite. There're bread crumbs stuck in in my keyboard from my munchies; they get smaller and smaller as I am typing... I just hope that I can crush them to quantum size so that there will be a probability for them to "superimpose" and get another serving of toasts, maybe.

TL;DR: At small enough distances, particles just randomly teleport sometimes. It's fucking weird.

So, this is only the miniturization of the switching. This is not processing capacity increase. This doesn't necessarily give a faster clock. What have you guy's been doing. There are nations decades ahead because the have learned to communicate with neutron bombs. Get it! Einstein's clocks where real atomic processing begins.

How can a computer be as small as an atom? A computer consists of more than 1 element on the periodic table so how does this work? Still confused

hrmm the more i look into quantum computing the more i think it's some kind of pseudo science like free energy or the hyperloop, too much theoretical assumptions that's not properly understood or tested that looks great on paper but will not actually work in practice. Take a look at the error rate problem for example, I can't see as how that would ever be solved. The whole concept seems almost barmy... Or is that just me?
