does anyone understand the google quantum chip

Willow

I'm watching vids but so far its escaping me. How the hell can it get information from the multiverse?

What's a qubit? and how can they repair each other?

What's gonna happen to my btc?

Please discuss

 

haha joe and julian have no idea what it is

 

I just watched a Nova program on this. I did not get all the basics. A qubit is the equivalent of a bit, in normal computers. But, a qubit is more than just a 1 or 0, it can be those, but I believe it can also be any variation between 1 and 0.

How you write programing for these things, I have no idea. Also, quantum computers are orders of magnitude faster than a normal computer. They take advantage of a so far unproven, but almost proven "law" of physics, (Quantum Entanglement) that Einstein didn't believe to be true.

This shit is way over my head, so I just go, uh huh, when I see shows on this stuff.

 

So my basic question is, if the quantum computer solved a problem that would take a normal computer longer than the universe has been in existence, how do they know the answer is correct?

Quantum is still a technical masturbation project to generate buzz and investment. The practical application and physical requirements to run one make it damn near impractical for anyone or anything. That's the part they never mention. It's the Fusion generator of the computing world.

 

It has been predicted that by 2050 AES-256 encryption will no longer be safe from quantum computer technology. Conventional computers would take millions of years (don't know about 13.8 billion years as is currently believed to be the age of the universe) to decrypt AES-256.

I guess if it was the nucular codes you would know the answer is correct if you could launch.

 

And on August 29th at 2:14am, Skynet became self aware.

 

Now we're talkin!

Put it into overdrive baby!

 

A main tenant of quantum mechanics is the wave particle duality and probabilistic nature of matter. This was experimentally verified with the double slit experiment. Showing that whether or not light is a wave or a particles when you observe it, depends on the probability of observing it in that state. This was illustrated with Schrodinger's Cat thought experiment. This reset the notion that matter and interactions involving matter had pre-determined and fixed states. Instead, this introduced the idea that matter, interactions of matter (energy), etc. were governed by probabilities. These probabilities are solved for with the Schrodinger equation. For example, wood is a solid when you observe it, because its composition of matter has the highest probability of existing as a solid. Water as a liquid. Etc.

So, in computing applications, I imagine it's an extrapolation of the above. Instead of a bit generating a binary response 0 or 1 (e.g., either the wood is solid or it doesn't exist). If given a prompt, with certain criteria, a quantum bit (qbit?) could "think" and stack rank the probabilities of all possible responses (e.g., wood as charcoal, wood as sheets, woods as paper) and work through them to figure out which one applies in a given circumstance. In essence, it's solving for several questions at once. Which is how, I'm speculating, it improves its computational speed / throughput.

 

How much more technology do we need ?

I'm good. I've plenty. Take me back to 2015 and leave me there.

 

Soon, we’ll have the technology to fulfill that wish.

 

Ask Sora to make a video explaining it to you and tell it to include a motorcycle in the video so you can post it here. I’ll wait to see what you can prompt! Blow our minds…

 

They are using the fact that quantum entanglement works to posit that there is a multiverse. And since their quantum computer uses quantum entanglement, it computes "in another dimension" or "through the multi-verse". Kind of glitzing up something that is pretty obtuse stuff.

They are essentially saying quantum mechanics things and applying them to what they are doing computing-wise because it operates in that world.

It does feel like they have been moving forward from the "building circuits" stage to "algorithmic". I don't keep up with it that much, but they are still trying to build a general purpose platform as far as I know. What a quantum computer does differently than a "classical" computer is complex and figuring out how to utilize it in a general way has been a tough problem to solve.

Some of the mathematical problems they have been working are specific uses. General uses (like code breaking or computer learning) have been mentioned but I don't think (publicly at least) they have been demonstrated.

We do a lot with "1's and zeros" already. Thinking up the "basics" for this stuff is harder by far.

 

Nope;

 

Some good explanations on the tube's. Anton Petrov, Sabine Hossenfelder are two of my favorite. But.......

 

Veritasium has a video on YouTube about it. His stuff is pretty good

 

Is that "nope" to what I said? I don't see a conflict in what I said and what you have highlighted...

I do think the statement is a little hyperbolic though. They aren't starting a gizillion processes in another universe to capture free compute cycles in those universes, which is what that statement implies. But it isn't a lie either.

They are using the attributes of a quantum qbit to solve a type of mathematical problem (which I don't begin to comprehend). Some of the complex states of a qbit seem to store those states (like spin or entanglement) or actually happen "elsewhere", which is posited to be a parallel universe of some sort (which I don't begin to comprehend).

How you write an algorithm to do this makes my head hurt to even think about.

A big breakthrough here is in hardware that allows the mathematical problem to even be attempted. The hardware is what Google is (rightly) bragging about.

Excitement about what is being done is justified. I was just trying to explain what I thought was going on with some very (very) limited knowledge. But, it is *really* hard to explain, even for people who actually are doing it.

In the computer science world, the very core of this is so different, it is like an electrician being presented with a "new' kind of electricity. "What do I do with that?" "Does it use wires?"
