Because for that to work you need something like a 128 qubit quantum computer.

Right now they can barely manage 2 qubits and it get exponentially harder with every qubit you add.

Ok, but what is a qubit

I really don't know what it is. Is it similar to a functional unit on a CPU like the fetch, decode, arithmetic or floating point units? I also want to see what he interprets it as

It's nothing, it doesn't exist

Then how are these companies building "quantum computers" able to do meaningful things with that they believe are "qubits"

One of the main companies is Dwave.
They claim to have a 2048 qubit machine.
If qubits are real, they should already be simulating the entire universe

Because they aren't meaningful things.

As if there are no plans or even the technology to create such technology. Its everything already on paper and it will be developed earlier or later.
Whats being pushes right now is Astrology (for what ever reason). In my view they start with the big >Above (Space,All,Universe) and than look at the Quantum >Belowe. Following the natural law of the occult knowledge.

Look into James-Webb-Spaceteleskop and realize what they are trying to explore. They come closer to find out how our universe was created. How they use this knowledge ... who knows. And not with "they" i dont speak about the Jews ... omg.

I remember Korea stealing tho
>google.com/search?q=north korea stealing money from banks

>being this retarded
No they just don't have enough qbits yet. Right now, a quantum computer simulator is faster than the real thing because of this.

What makes you think they haven't?

IBM claim they have a 20-qbit quantum computer.
Which means that CIA has a 200-qbit quantum computer.

>If qubits are real, they should already be simulating the entire universe

But the universe itself exists in quantum uncertainty.
For example: a photon moving through a piece of glass takes each and every one of an infinite possible paths through that glass.
Only by computing the sum of all those paths do you get the exit position and direction of the photon.

Is this pasta and we all fell for it in the other thread?

Has anyone even been able to make a quantum computer make anything useful, what do they even do? Serious question, sorry I'm a brainlet

A bit that can be either a 1 or 0 at any given time until its observed

how do I encrypt my hard drive with this

Do you remember the Hubble space telescope and how impressed people used to be?

That one's pretty tiny compared to the two space telescopes from the same era the CIA donated to science because (apparently) they are obsolete now.

There are different implementations of quantum computers, and qubits. They aren't built from traditional logic gates (AND/OR/NOT subsets), they're built from Pauli X/Y (Z also but you can construct the last gate given two of the other gates), Hadamard (critical for decohering qubit states into dual superposition states), and CNOT to introduce multiple qubits.

Essentially qubits are two state quantum systems, and the gates manipulate this quantum system by rotating its state along the Bloch Sphere whose components in the Lx/Ly/Lz space are the respective amplitudes of the state wavefunctions and hence maps to a probability of observing the state. Rotating this state into clever positions where multiple spinors representing different qubits interfere in the right way can alias solutions into the frequency of the wavefunction, which is how most quantum algos are currently being developed (via QFT).

Qubits are implemented using spin available or valley states (e.g. photon polarization). For instance, discrete state systems like doped quantum dots, typically InAs or InP, but also possible in ZnSe and CdSe to lesser degrees.

There are tons of potentially useful quantum algorithms in the academy. It's just we haven't been able to build a large enough computer to run them with real-world data

Naw, quantum computers are just for grant farming. Nothing else.

>200 qbits
Great, and my web sim can simulate thousands in realtime. We have a ways to go

kek sims are nothing compared to the real thing.

Thanks user. It's hard to find anything concise that actually describes what these computers are doing.

You don't
This, look up shor's algorithm
For the time being sims are much much faster. We need moar qbits before sims will be slower.

What we need is an impossible grasp of metaphysics, so that we can use non-deterministic randomness to force outcomes and solutions with arbitrary inputs.

Think bogosort, but it is always correct on the first try.

We need to dump more money and brain power into quantum research, and reignite metaphysical studies.

>We need to dump more money and brain power into quantum research
we are already dumping too much you cocksucker and for what? nothing

Although quantum computers exist, they are so ineffective that
they can just about do some small calculations. Quantum computers are still in the experimental phase and will be for at least another decade. IBM has a quantum computer, which, if you are a university student you can actually use it

The math is relatively simple.
The hard part is to accept the quantum fuckery.

>metaphysics
Quantum isn't metaphysics
>Think bogosort
Wrong. In laymen's terms, you write you're program so that all the wrong answers to your problem cancel each other out leaving only the right answer.
>but it is always correct on the first try.
Currently, not at all. They have to rerun it because of noise and such. The tech is early.

>Shor's algorithm
Yeah, I posted this on the other quantum computer thread, but here it goes again. I think this gal's explanations are great for all levels

Bogosort is really underrated. After all it's a sorting algorithm that runs on constant time! (only two possible outcomes: sorted or not sorted)

A mastery of quantum particles promises unforseen benefits in engineering. A new generation of metamaterials, made of exotic matter. Imagine a system of molecules that allowed for the effecient conversion of gamma radiation into kinetic energy.

Economically viable nuclear transmutation is another distant benefit. We already have mastered nuclear transmutation, we have invented and reproduced alchemy. The problem is that our abilities to execute this is reliant on massive structures that work in extremely small quantities.

As we come to understand our quantum realm mire intimately, the economics associated with manipulating it will become viable for industrial application.

Our quantum fabrication capabilities are extremely poor currently. We must press on.

>Imagine a system of molecules that allowed for the effecient conversion of gamma radiation into kinetic energy
Doesn't mean it will ever happen or is possible though.

All the smart people in Russia ran away to the west a long time ago, all that's left are the millionaires/billionaires that robbed the country in the 90s and people too stupid or too stubborn to leave. Russia has a piss poor semiconductor industry and actual smart people are looked upon as threats desu, it's all about being able to abuse the system.

I'd be very surprised if Russia is able to build a quantum computer around the same time as Western countries.

t. Russian

>quantum isnt metaphysics
I explicitly seperated these terms for a reason, why do you insult me?

Additionally, I am not talking about using our current conceptions of quantum computing. Or even utilizing computers to achieve these results. Only using them to reap the rewards of reweaving the fabric of reality.

How do quantum computers differ from ternary computers?

OK, I understand now.... Why would you think this even possible? Quantum mechanics is observable and predictable. I don't see much how what you are suggesting is related to quantum.

A lot

That is not the attitude that has ever driven the development of technology. Millions of years ago, your ancestors laughed at the idea of picking up a massive rock and hurling it a great distance for its destructive force. Only in the last few thousands of years we developed and refined artillery. In the contemporary era, this is a hugely trivial concept... only because we stumbled upon the answer in a never ending trudge of bruteforcing how our reality works.

We have learned that concepts we took for granted, such as time and the interpolation of mass, are merely emergent behavior and do not discretely exist at the fundamental level of our existence. What new feats will we be able to achieve if we gain a more complete understanding of this quantum domain? I cannot say, no one can. But we won't figure anything out if we neglect research.

Only to an extent. And there are many properties expressed by the physical world that are not expressed by the quantum underbelly. These gaps are poorly understood, and changing that has the potential to offer great insight in emergence at the very least.

>Any proof of concept on an actual quantum computer when it comes to cryptography?
Shor's algorithm "worked".

>IBM calculated that 15 = 3 * 5
Quantum supremacy confirmed

Current quantum computers aren't because they are too noisy. Quantum computers that will be capable of cracking encryption(running shor's algorithm) are decades away. We are now in the era of noisy intermediate scale quantum computing:
arxiv.org/abs/1801.00862

Completely different math.

But that's not how qubits work retard

Based futurist user

I've done some research in the so called quantum information for a few years and from my perspective even the quantum algorithms already have some serious problems with defining explicitly things like quantum oracles and black boxes. Hardware has probably at least as many problems. If someone were to ask me how dangerous are quantum computers for cryptanalysis, I'd say - chill man, they're harmless at the moment.
