Quantum computers are in the "Maybe it's possible" phase, still 10 to 30 years out, like nuclear fusion.
One working-example of a quantum computer is the double slit quantum eraser experiment:
youtube.com
He explains how it works from minute 0 to 6, then explains the wave form collapse. The floating point operation would be done IN the cross-temporal wave form collapse.
The Problem is, the hinge that either reads or writes a photon to the photon gun, reads either screen, or flanges the erasure is limited by the speed of light.
And so you would need to stack this 32 units high to perform a single floating point operation. And it would only go about the same speed as a CPU does. At the speed of light.
But the attempt of offloading the FLOP to the wave form collapse in a cross-temporal pre-post realm of subatomic particles is not disproven by math.
So research continues.
Yes 99% of it is bullshitters flim-flamming for coins. But what research isn't?

nice post

Yeah they pretty garbage right now. I have a tech buddy who has a theory that their success may be tied to consciousness but that would bump into the conscious universe theory. he was basing it off of how they inexplicably stop working or some shit like someone stopped believing.

Also I talked to a guy over beer claiming to do pure research around legit quantum computers, and I felt like I got the real scoop: the general idea is nanotechnology around an atomic mono-layer of heavy metal atoms.
You create a atomic mono-layer lattice of cesium atoms. Think of it like a bug-screen on a porch or super-fine fly-netting.
Your first problem is preventing the cesium atoms from quantum-tunneling to their neighbor slot, so you've got to hold the thing in place such that purtubrations at the atomic scale don't unhinge the entire thing.
You take your cesium mono-layer and arrange them into chip diagrams in almost exactly the same way as here:
youtube.com
and
youtube.com
and
So then you stick your handy-dandy write head on one side of the lattice, you write your subatomic particle spin, say spin-up or spin down. That proceeds down the lattice at the speed of light, (you broke out teeth of the lattice, so that the propagation only occurs along valid lines), and then you put your read head on the other side. In theory a computer would not heat-up, because subatomic particle properties of atoms don't create heat.
And the theory is that a quantum tunnel could be made between two points on the computer board, and so therefore a read and a write could travel from one side of the chip to the other side of the chip, using zero time, and the spooky-action-at-a-distance that Einstein didn't like, but was proven to be possible.
He talks about the read/write head here:
youtube.com
And so the double-slit quantum erasure experience in my previous post becomes the "Tunnel of faster than light travel" between one side of the CPU and the other side of the CPU. Thus making it possible to perform a calculation in 0.1 nanoseconds rather than a universal speed limit of 1 nanosecond.

Very good at solving complex problems that are specifically suited for it, horrible at other tasks. So worthless unless you want to solve something on a probabilistic manner and not recieve an answer
Liam Jackson
And this set of problems is very small, reserved mostly for research, development and military.
Xavier Lewis
Yes, people usually don't understand Qcomputers are not aimed to replace classic computers, but to skip several classes of compexities for certain specific problems (combinatorics, game theory...)

Don't agree at all, it could help in many fields (finance, genetic research, fertilizer optimization etc...)
Hudson Allen
They'd have you believe quantum=magic. Some good uses, lot's of memery around them.
Asher Sanchez
there's a good /sci/ thread for this but i dont feel like finding it
Isaac Thompson
good post
the hype about it is definitely at meme tier levels. People at large finance companies are worried that in 5 years people will be using them to crack encryption.

Why don’t they connect a human brain to computer and turn the brain into a computer? The human brain is an excellent organic computer.
These mechanical computers heat up really quick and break down
Biological brains and biologically grown computing devices would be way more energy efficient and smaller in size
Colton Allen
The research field of Quantum computers is just people attempting to figure out how to perform a Floating point operation in subatomic particles that recently demonstrated the super-power ability to:
1. Have a piece of information travel faster than the speed of light as a non-corporeal property between two locations, exploiting the non-locality of atoms in this universe.
2. Reverse the flow of causality in order to retroactively change things in the universe that have already occurred, proof of this is found via the double slit quantum erasure experiement.
A quantum computer would not rely on electrons travelling down a wire, instead, a quantum computer relies on either the propagation of subatomic properties of atoms, or the reality-bending properties of photons that apparently are able to store a bit of information where they were first created, in a cross-temporal way.
We could in theory make a hard drive where a bit of information was stored in this cross-temporal place, then perform a floating point calculation in this non-corporeal place, thus shifting the heat of your CPU to an alternate reality before photons begin to exist.
Then God knocks on the glass and says hey you fuckers, quit splashing your atoms outside the tub. I put you in there for a reason.
Brody Miller
Good idea, but almost impossible to execute.
Daniel Butler

Military tech is always 10-100 years ahead of what they unveil to plebs like you. Google and most big silicon valley tech as well as military companies are already run by quantum computer AI systems.
>The MAGI system from eva is real.
Thomas Anderson
No sorry
Joshua Thompson
Quantum computers are way real. I learned everything about them from Big Bang Theory.
Adam Gomez
Yes, sorry frogtard. Your country doesn't have that tech and that's why your retarded EU is collapsing
Joshua Bailey
>10-100 years ahead
retarded bullshit.
tech does not advance at a fixed pace,
the past 200 years was the time of advancement, little was done before them, and we are now over the hump and can expect little to none going forward.
Ethan Lee
It's bullshit but at the same time it's not, it's the modern equivalent of perpetual motion, the hardest thing to break through is utilizing massive amounts of qubits and the noise problem. If I could make a point it would be similiar to finding out teleportation is real and now people are working towards teleporting an entire human body, something like.
Thomas Lee
the brain is good at doing tasks related whatever you need to live. Anything outside it's shit.

Idk what this other guy in here is on about FTL computation. Quantum computing has literally nothing to do with that. Even if you have entangled particles, you need to transmit how you measured the first particle over a classical channel to know how to measure the second without destroying it's state...you are never going to get FTL computation from this.
However, because you can entangle particles and have superposed states for your memory registers, you can exploit the structure of certain problems to get a speed up in terms of algorithmic complexity.
In the most general, a quantum computer lowers the complexity of a brute force search for a given output over an input space over N to sqrt(N) evaluations instead of the entire domain:
en.wikipedia.org
So essentially we have the algorithmic framework that provably demonstrates the advantages of quantum computing -- especially with respect to discrete logarithm problems which underlie the widely used RSA encryption algorithm. (Shor's algorithm on a quantum computer can easily break this)
The limitation is only in the difficulty of creating the hardware.
Jose Reyes
Quantum computers are bullshit. Another term would be 'computer computer'. Most of you niggers don't realise that quantum just means that something is counted.
Jace Gonzalez
Quantum computing is hard to explain because it requires a lot of background knowledge of terms to even get you foot in the door towards understanding.
But two things I'm pretty sure of.
>they won't fully replace conventional computers we have now, they don't do every single thing better
>they can sort through information in databases much faster
Evan Cook
The physics definition of the Quantum is the one used which means atoms are only atoms because of the number of photons and electrons that they have.
When an electron moves from one shell to another, the atom undergoes a quantum leap to another energy level at faster than the speed of light.
And so a better name for Quantum Computing might be: "subatomic particle computer" that leverages writing and reading attributes smaller than that of one atom to perform addition and bit storage.
Another attempt at quantum computing is by arranging the subatomic particle computer to only observe the correct answer. And so the electron is fired at the screen. An infinite number of calculations are performed in a cross-temporal object, and the correct answer collapses the wave form, betraying the physics engine of it's CPU cycles to render physics, but instead to perform a calculation for our physics.
Basically robbing God of his computer physics engine for our purposes.
Aaron Fisher
I've heard that one of the hardware difficulties is that the qbit topologies are not scalable, each time you want to add a q-bit you have to rethink all you qbit architecture. It really has a 50's mood I like it.
