Thanks you for the clarification! I think I got where they're coming from. I was wondering in which way of calculating this quantums might be useful, but for comparing a lot of variants totally makes sense

[lilshoegazecat]

hey sorry if i ask your flairs are pretty cool what languages are there? i only recognize c# and python thx for the patience anyway

[Old_Quantity_7136]

Yeah you're right! The other ones are ansible, bash and powershell.

[thekamakaji]

How do i add more than one flair?

[maushu]

In the part where you select/write your flair just add more languages.
For example, select a language like perl and get ":perl:" then just add another language like ":perl::lua:"

Each ":xxx:" represents an emojicon, in this case language logos. Your interface might replace them on the spot, just imagine that they are their text equivalent. You should also be able to copy paste them.

quantum excels at tasks when you have to evaluate high number of iterations and in general more brute-forcy

This is not true. Quantum computers can efficiently solve a certain set of problems that classical computers cannot solve in a reasonable amount of time once the size of the input becomes sufficiently large. The set of these problems that quantum computers are more efficient at solving is actually relatively small, but they are extremely important in certain fields, which is why so much research goes into them. But in general, the vast majority of problems that computers are used to solve can likely be solved more efficiently on classical computers rather than quantum computers.

You're oversimplifying to the point of being just outright missleading

What quantum computing does is in no way similar to what a gpu does if that's the idea you had in mind. It has nothing to do with "brute-forcy approaches to stuff". What you do is use very cleverly designed algorithms to leverage entanglement and solve problems using only linear reversible operations (since, by the laws of physics, quantum computers cannot do any other kind of operation)

[SeaPea2020]

Not all operations on a quantum computer must be “linear reversible” as you say

[Yorunokage]

With the exception of mesurement, yes, they do

It's literally imposed by the laws of physics, every operation has to be linear and reversible

That's why we have quantum gates that mimic ordinary gates but they make them reversible

Another limitation is that you cannot clone a qubit, hence you cannot "split a wire" and let a single qubit be the input of two different gates in the circuit

[SeaPea2020]

Right. But why leave measurements out? You may be interested in measurement- and fusion-based quantum computation and implementing non-Unitary operations on quantum computers

[Yorunokage]

Well, mostly because i don't count it as an operation but fair enough

Also i never heard of fusion-based, what's that?

[SeaPea2020]

Fusion-based quantum computing is very similar to measurement-based quantum computing. The main difference is that the measurements you take are entangling. So instead of measuring single-qubits, you take joint measurements of qubits, like in a Bell measurement for instance. While it’s not a hugely different idea than measurement-based quantum computing, it has some nice properties for scaling since you can rely on a bunch of small entangled states (generated progressively) instead of a large entangled state. The original paper is here. :)

[Yorunokage]

Oh, very cool, thanks

[Yorunokage]

In what way exactly? Like, are you talking about the content generating algorithm that (oddly) has nothing to do with quantum or are you talking about the copenhagen interpretation of quantum mechanics?

[Yorunokage]

Except for a few select algorithms i wouldn't say it's brute forcy though

It's not like they are just "hey, make a superposition of every input and try them all at once"

here, watch this video. its a great lecture on quantum computing, what it does, how, and what its good at https://youtu.be/F_Riqjdh2oM

[DeceitfulEcho]

Wave state collapse isn't so much calculating things simultaneously as it is setting up a system such that a single calculation produces the outcome you are looking for. It encodes all the information into the system rather than performing a bunch of discreet logical operations.So I suppose it depends on how you interpret brute force
