here's the thing, there are two types of workers in quantum computing:
>lex fridman-tier silicon valley corny ass computer scientists who think they've got it all figured out after doing a summer internship at Google and watching a kurtzgesagt video on how q-bits are just ones and zeros at the same time engaging in machine learning research for quantum computers when NISQ devices still can't even factorize 3 digit numbers..
>physics autists who can't program a computer to save their lives and have zero understanding of computer architecture yet think that by virtue of having a physics degree, they are qualified to work on anything remotely technical, waste time and money trying to figure out how to keep atoms coherent, and will tell you with a straight face "we just need 4 quintillions more qubits and it'll work, trust me bro!"

This shit needs a new research winter to weed out all the fakers and maybe we can start on strong grounds again.
Think about it, Google, IBM and a bunch of startups have been pouring unholy amounts of money on this shit and we've yet to see it do anything even remotely impressive, that's the biggest sign that the current research is headed in the wrong way. We need someone who's both well verse in hardware architecture and physics to develop a new paradigm. But the current generation of researchers prefers publishing about "quantum AI" or whatever that is.

Look into ibm's stuff. Im convinced.

ok how do quantum computers work
explain it with the simplest possible example of a basic calculation
Sure you have particles in a superposition of states, say these states are coherent and highly stable.. where do you go from there to make a computation?

Look at this video and tell me.
Quantum revolution is based on it.

When I first saw it i was in shock.
The experimental setup is so primitive that any conclusions are just whatever we can make up to explain the behavior.
Insanity.

I honestly don't know if it's a scam or not.

For instance are quantum computers actually interacting with real world particles or is it simulating the environment of said particles?

Is the noise that constantly talked about interfering with it related to all manner of vibrations? Or is noise related to any exterior interaction that could leak into the interior environment of the quantum computer?

Is the quantum computer trying to solve real world problems via interacting with matter at the smallest scale or is it just a glorified super computer focused on the P vs NP meme shit through simulation?

>Hearing about a computer that speeds up algorithms by splitting the work between parallel universes and not realizing you are watching boomer cope and mental decay in real time

100% scam. There is no such thing as "superposition". It's just INDETERMINATE state. It's like the far side of the hill outside my window. Now, I can't see what is going on behind that hill. It can be in any number of states. So its state is INDETERMINATE. It would be pretty ridiculous to claim that it is in all number of imaginable states ALL AT ONCE, wouldn't? But that's what they claim when they are talking about the state of particles and "superposition"!!

Oh, and if that doesn't cut it for ya, let's examine complexity class BQP. Now, that's the class of functions that can be calculated in efficient time by a quantum computer. Namely fast integer factorization runs in polynomial time, and so does Grover's algorithm, which is searching an unsorted list. Now, it's really never been proven if BQP≠BPP or BQP=BPP. BPP is the class of randomized algorithms that run efficiently on classical computers. So in other words, fancy algorithms on regular computer.

Oh and one other thing. Integer factorization is NP-indeterminate. That means there's no algorithm that runs faster than subexponential time on a classical computer that we know of. It's not equivalent to other hard problems in NP. So it's not NP complete. There might be an algorithm out there that can do fast integer factorization in polynomial time out there (the above mentioned BPP class). But also, there's OTHER problems that are very similar to integer factorization that are NP indeterminite also. The hidden subgroup problem. Subgraph isomorphism. Very important problems. But here's the kicker: these "quantum computer researchers" NEVER EVER MENTION THOSE PROBLEMS. If I were a quantum researcher, i'd make a freaking name for myself by dreaming up a "quantum algorithm" that could tackle those problems. You'd probably get a number of prizes for that and have your career set for life. But NOBODY even ever MENTIONS those problems.

I assume it just has some degree of bias against technobabble, as I've had this website claim my snippets of my erotica reached over 130. Conversational English also tend to lean towards the simplistic

Why’s it hanging from the ceiling?

>>16001566
Because it has to operate in a cryostat. It's cooled by liquid helium and it's easier for that to flow down into the apparatus than it is to be pumped up into it.

Jurgen Schmidhuber says it's a scam and he's always right and first.

>>15998909
there's been a lot of progress it's just not in any tangible manner that affects us consoomers. IBM for example has created high qubit processors that remain stable long enough to put to work.

Quantum computing will never work. Keeping enough qubits stable long enough to do any significant calculating or processing, is a mathematical impossibility. The whole idea that one day quantum computers will discover new miracle drugs, or crack public encryption systems, is a mirage. Even worse, it’s a hoax.

Tl;dr super-cooled fluids have a tendency to crawl up the walls of their containers, and vibration is detrimental to the operation of such a machine, so it's just easier to hang the thing like a chandelier than it is to try to build a box for it that sits.

Is there nothing sacred anymore? Must everything be regurgitated to the masses in short video format for the fleeting dopamine rush of thousands of (you)s?

>>16002187
I think they waiting for one big thing to calculate with it one time. You can't use it all the time but you can get one good use out of it. Maybe multiples
