What the fuck is this shit?

HAHAHA

Quantum computing uses the principles of quantum physics, allowing the use of ternary or higher order systems efficiently. 99.99% of journalists have no fucking clue what it is though.

>(such as weather patterning

If that were true the article would have bragged about how it will predict to the minute when it's going to rain next week in your neighborhood.

>or nuclear explosion simulations

Like anyone gives a damn about being able to destroy a metropolis any more effectively than we could in 1960.

Journalists don't know what quantum computers are, they just report what they're told.

Governments with nuclear weapons spend billions on supercomputers for this exact purpose.

You meant "waste", I assume.

Quantum computers manipulate the 'state' of a bit based on quantum physics thus expanding its informational content.

Just about every computer that's around you uses quantum physics on a different scale/granularity.

Quantum computing is a meme for brainlets who don't understand combinatorics, what a bit represents, and/or information theory.

It's a use of additional states of electrons. The digital computers we use today do not do this.

Exactly what was stated in more specific details.
> The digital computers we use today do not do this.
Because it doesn't scale well and is fucking retarded beyond combinatorics

So, like, can they actually break encryption or anything or are these just toy problems that mathematicians came up with explicitly to find problems that are easy on Quantum exponential on deterministic?

>turn on computer
>universe collapses in a quantum singularity
THANKS Google

They likely can, but releasing that information would be unwise.

>Because it doesn't scale well
Google is scaling it. 72 qubits allows for quite a bit more information processing in a short amount of time.
>fucking retarded beyond combinatorics
Not sure what your problem with combinatorics is. Graph theory has been used to great effect to solve complex problems, particularly among social media networks.

You can't hide math.

>2048-bit RSA requires roughly 4096 qubits while a quantum computer to break the equivalently secure 224-bit Elliptic Curve Cryptography requires between 1300 and 1600 qubits

Yeah, I ain't sweating.

>quantum supremacy
That's racist and sexist.
Wtf google?

It's just the Basilisk getting stronger
Nothing to see here move on

Fair, they can't at this time. I would argue that they aren't terribly far from it. Quantum computers are expected to increase in power faster than traditional computers (doubling qubits roughly every two years).

Two sample sets does not a Law make. The fact that they're already struggling at double-digit computers means that they have no idea how the scaling is going to work. Whereas with Moore's law (which, is, frankly, far less meaningful than the architecture developments) we always knew exactly what needed to be done, it was just a matter of figuring out manufacture methods to make things that small.

To break encryption you'd need millions of qubits. Not anytime soon.

Quantum computing researcher here

From what I’ve seen of private industry, I really doubt they have a fully universal 50 qubit machine, meaning i bet their equipment might be able to do certain kinds of problems well but not everything you’d like to do with a QC. It all seems like marketing and posturing

The math behind a quantum computer is totally legit, and if you knew the algorithms you would understand that someday this is a real possibility. However the ability to operate on all of the quits in your machine simultaneously is still a big problem to be solved. Should mention that the ibm guy in the article is right that QC and classical will work in tandem and quantum computers aren’t going to take over

Also for what it’s worth don’t count on the government to do anything useful lmao I’d trust the academics on this one

D-wave has been progressing at that rate. The problem they've had with general quantum computers is the error rates. Once that is fixed, we should see consistent progress.

see

And what about error correction?

It's an issue that still has to be overcome.

The problem can be solved with lots of qubits.

That's the ham-fisted method, yes.

alright question, when they talk about x qubits, isn't that just a register?
how is it actually useful for anything? are there special devices to interact with the register?

>Two sample sets does not a Law make.
Moore's Law was literally made from two points of data.

and it's not turning out right is it?

The thing is, those registers contain a ridiculous amount of data.
2 qubits = 4 bits
3 qubits = 8 bits
4 qubits = 16 bits
100 qubits = 2^100 bits
It escalates quickly.
So by operating a few physical qubits you can process a lot of data simultaneously.

It did turn out right. It followed the law for like 35 years until it changed due to physical limitations. Holy shit you're a massive retard get . You know nothing just like everyone else on this board.

quantum shit doesn't exist, we're not living in a video game
it's all memes and pr

arxiv.org/pdf/1712.01356.pdf

you're right except the second point

yeah but... how do you perform operations on the qubits?
if you 'dropped them in' to a normal computer system they wouldn't behave that way would they.
for example what does a & b mean if b is in the special third state and a isn't? my basic understanding says that b randomly becomes 1 or 0 making a & b also randomly 0 or 1 also which sounds useless
don't you need a 'special and' that always returns 0 in this case?

Googe the quantum circuit model

Logical gates, just like in a classic computer.
Randomly within the probability.
When you read two entangled qubits they can give one of four states each with a different probability. For example:
00 - 20%
10 - 15%
01 - 50%
11 - 15%
Basically, quantum computing involves changing those probabilities to get the desired answer.

>Governments with nuclear weapons spend billions on supercomputers for this exact purpose.
No one is actively developing new or more efficient nuclear weapons. Some are developing new delivery systems, but you don't need a fucking quantum computer to do that.

The only reason the U.S. spent billions on supercomputers for nuclear explosion simulations was because of the global test ban treaty. Without being able to light a nuke off in a cave once in a while we have no way of knowing if our stockpile will continue to work without billion dollar simulations.
