Quantum computing will turn everything upside down

You're taking things a little bit too far, don't you think?

Have some respect.

Are we still in the beginning “over promise, under deliver” stage of this tech? Looking forward to the inevitable reality crushing real world usage followed by the eventual achieving of 80% of the expectations a few decades later.

Unless LK-99 is a superconductor, not much will change. To achieve a quantum computer currently you have to have near 0 temperatures. It's not like this will be in our handheld devices anytime soon.

Wouldn't the first country to develop this have the capacity to decrypt all information of any country that can be reached by the internet? Digital barriers would stand no chance, you could just straight up get taken over or at the very least completely exposed.

Quantum computers are cool and all. But we have yet to solve the problem of quantum decoherence (long story) in a way that doesn't involve us cooling the system to near absolute zero using the (on earth) ultra-rare Helium-3 and relying on super conductors. Until then they will be far from practical and spend more computing power correcting their own errors than what we can actually use.

Quantum Computing is really good at solving certain things (like really efficient search algorithms (Grover Search can find an element in an unsorted(!) list in O(sqrt(N)), for example. Or application in factorization problems, which is why some cryptographers freaked the fuck out back then) but are not that great in other tasks like for example normal file-system shit where you'd need to work around the no-cloning theorem. And tasks where data integrity of long sequences is a problem because the models of quantum computers (at least to my a bit outdated knowledge) are all probabilistic models (which is not surprising given the nature of Q-Bits), which you'd need error-correction mechanisms just for ensuring that everthing remains stable (Q-Bits are a lot less stable in general, this might get fixed over time, who knows. But right now, the rule of thumb is: The more gates you add, the more potential noise you introduce into your probability distribution, the more shit you need to add to denoise/stabilize it).

I think, as with many other things, this topic gets overhyped to hell and back.

"Google has unveiled a new chip which it claims takes five minutes to solve a problem that would currently take the world's fastest super computers ten septillion – or 10,000,000,000,000,000,000,000,000 years – to complete."

Bet it still can't answer why women won't just say what they want :p

I like to think that we really are living in a simulation, and quantum computing is our way of exploiting our own code.

Digital computers work with ‘bits’, noughts and ones, ‘a very crude approximation of reality’. But quantum computers use the qubit – the state of an atom – as a unit of computation. As we know from quantum theory, atoms can point up or down, but also spin: ‘There are infinitely more states than just zeros and ones…

So atoms are basically:

It is quite literally the birth of 'almost real' artificially intelligent researchers. A single Auto GPT set up on a QCPU can in effect simulate 10,000 human researchers working 24/7 for their entire lives and output it every few seconds.

What do the researchers and lab assistants whose jobs might be on the line think of this?

Still seems like there are too much uncertainty/unreliability regarding quantum computers to get anything interesting done with them. That’s my impression at least.

It’s a cool concept though.
Uncertainty is literally the concept of a quantum computer.

Uncertainty is literally the concept of a quantum computer.
I can’t really recall my specific line of thought when I wrote that.

But yes, and it’s worthless if it’s too uncertain. Doesn’t matter if a quantum computer can theoretically solve a problem that’d take a regular computer X amount of decades to solve if you don’t know if its solution is correct or not. I’m not too invested in this topic but I imagine the main goal/load of work is trying to make these actually become reliable with answers that are at least 95% probable to be correct.

But maybe they’ve manage that already? I’m not all that invested in the topic.

What I find more fascinating is the error rate. So, if they run it 100 times they can get a bunch of different answers and the more they run it, the more likely it is there are errors? Kind of shoddy if true...

At least it can play modern Zelda for you.

Why? Because quantum computers are unimaginably more powerful than the digital sort.
Idiot.

Quantum "computers" leverage physical processes that have certain type of equations behind them, to sort of (not really) calculate thinks previously unthinkable.

It is absolutely not a generic computing device, nor is it even remotely conceivable that you could run something as simple as notepad text editor on it.

:unsure:

Maybe, just maybe, if we can fit these into lady brains we 'might' get an answer within a week of where they would like to eat when asked what restaurant they want to go to..

Either that, or
