>because quantum mechanics is a bunch of garbage nonsense
But it isn't garbage nonsense. Quantum mechanics is the reason why your computer can fit in your pocket.

>Here’s my layman opinion on something I know nothing about

>>11266863
Kinda agree. I mean the theory is true and functions. But it feels like pulling teeth trough ass.

It seems like it both heavily lacks something and is laid out from the wrong end.

Kinda like instead of drawing circle in radial coordinates, you plot sine and cosine and then cant figure out how exactly the circle looks like.

So it's a nice mathematical instrument to calculate when electrons will tunnel or something but is a barely a theory to explain universe.

>I don't understand something therefore it is false
Is this quite possibly the worst type of argument?

>>11266863
Quantum computing research isn't garbage. There are a set of compelling reasons and papers that suggest that we have a direction to go towards understanding quantum computation and building a quantum computer, and there are concerns and open questions about its feasibility - this is normal and healthy for any nontrivial part of math, science, and technology.
>because quantum mechanics is a bunch of garbage nonsense
not really. There are succinct ways to predict the results of experiments, which tells us the theory isn't garbage, but all the popsci explanations tell you that it's not a theory that lends itself to conventional explanation. The short of it is that you shouldn't think too hard about the ontology until you have more experience with phenomena from other fields, and you should understand that quantum mechanics gives you a set of tools that let you predict the interactions of 'quantities' after 'experiments.' As long as you can accept that, quantum does exactly what it was made to do - the only problem is that it isn't clear about its ontology, and you should reserve judgement until you read more physics.

I'm almost tempted to say you think it's garbage because nobody outside of the actual big writers in quantum computing can explain it without saying "le parallization, le more states" which is *not* what makes quantum fundamentally different when talking about computation. Say what you will about Aaronson, but when he says that superposition in computing is a phenomenon that doesn't have classical analogue to "and, or" relations, and that all the quantum 'magic' is a mathematical consequence of complex probability amplitudes over strictly nonnegative probabilities, he was right.

Its true, quantum computers can only do basic math and subtraction at a kindergarten level.

I want to play video games on a quantum computer.

This.

Who cares about that faggot? Do you really think he's a proper physicist?

Can you elaborate on this?

any anon whos more knowledgeable in my on this please do correct me, but essentially Computers are basically any machine that can compute values (Basically take in an input, processes, store, and output, I think). A calculator is a computer, Tvs are computers too; the difference is, is that laptops and desktops are general-purpose computers and as such have multiple functions in general. Now that also includes cell phones (which is what I think what anon was alluding to).

>As part of the research program in 1975 and 1977 at the department of physics at The City College of The City University of New York, Kaku worked on research on quantum mechanics.[6][7] He was a Visitor and Member (1973 and 1990) at the Institute for Advanced Study in Princeton and New York University. He currently holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York.[8]
>Kaku had a role in breaking the SSFL (Santa Susana Field Laboratory) story in 1979.[citation needed] The Santa Susana facility run by Rocketdyne was responsible for an experimental sodium reactor which had an accident in Simi Valley in the 1950s. Kaku was a student involved in breaking the story of the leak of radiation.[citation needed]
>Kaku has had more than 70 articles published in physics journals such as Physical Review, covering topics such as superstring theory, supergravity, supersymmetry, and hadronic physics.[9] In 1974, Kaku and Prof. Keiji Kikkawa of Osaka University co-authored the first papers describing string theory in a field form.[10]
>Kaku is the author of several textbooks on string theory and quantum field theory.

first thing is true unconditionally, second this is true only conditionally. overall 7/10 insight, you just need to overcome your aversion to patchwork explanations

I was sitting in my 11th grade history class. My history teacher said "quantum physics is not real". Immediately, I stood up and asked why. He said "there is no evidence". Typical low IQ statement. I started reciting quantum physics equations from my memory. My history teacher stuttered in disbelief, dropped his books and ran out of the room. Everyone in the class stood up and cheered for me. It felt great being smart. Suddenly, the principal walked in and asked for me. Everyone else sat down and I left and went to his office. He asked me why I made the history teacher cry. I replied "sir, my intelligence can not be handled by the weak minded". He thought and then brought out an IQ test. I took it, and within 15 minutes, I had finished. My score was 168. While I was not surprised at all by this number, my principal was absolutely amazed and was at a loss for words. I went back to class and my crush walked up to me kissed me. The day resumed as normal until I went home. I had a letter in the mail. It was from Harvard.

The dirtly little secret is that all quantum tech was designed and prototyped 30 years ago.
We havent moved an inch since.

Hopefully this explains it.

TL:DR To make really small computer parts, one needs to understand how electrons behave at very small scales, and quantum mechanics is the only framework which explains that adequately.

i also used to think that quantum mechanics is just math and theoretical physics magic then i realized it's just physics for smaller stuff.
if you are familiar with plato's forms theory think of subatomic particles as forms with set features not as physical spheres like the ball you kick. these forms are hard to observe so we describe them using observable allegories/analogues and math

He's a pop sci puppet. His books and talks in the last 15 years are meaningless. He's not a proper physicist, even if that was different in the past.

>>11271794
No. He's making money by saying incorrect things. There's no reason to take him seriously on regards of QC.

Keep pulling the thread brother. Soon the while sweater will unravel lol.
Quantum mechanics is also a hoax.
Read this thread if you want to know more. You have to read the whole thread though.
