This is such a fucking stupid statement and I’ve seen it in every thread discussing this shit.
Just because its obvious doesn’t make finding more evidence of it not news. This sort of “well duh” attitude plays right into normalizing the idea that hostile foreign governments are spying on us so effectively that im convinced it was started by 50 cent army posters who convinced regular dipshits that it was some brilliant and hilarious response.
Its not funny. Its not clever. It basically derails any discussion because “so obvious, I already like, knew that.” Honestly shut the fuck up if you have nothing to contribute and take your low effort bullshit back to reddit.
No, I had my breakfast. In the form of a shitty meme tier sandwich supplied by unoriginal assholes while I’m trying to get additional insights into the articles I’m reading.
I don't envy French voters, who will be forced to choose between Macron's successor and Front National in the next election.
Because presently it seems like Macron, the police, and young French muslims are cooperating in a concerted attempt to enflame the situation and help get Front National elected. And all while Europe is defacto at war, facing an existential threat in Ukraine.
Lucky that Macron can't run again, but it'd be nice if he didn't run a key NATO member into the ground while blaming it all on video games.
As a 70-qubit quantum computer, it’s not going to be doing many helpful calculations. The benchmark used is random circuit sampling, which is doing a bunch of random quantum operations, and then reading the result, and it is compared to a supercomputer simulating the various random operations. This algorithm isn’t useful outside of benchmarking.
This also makes Sycamore a particularly ineffective “weapon” considering that we don’t really use encryption that’s less than 1024 bits, which is well outside of the capability of our current quantum computers.
I am a large language model, also known as a conversational AI or chatbot trained to be informative and comprehensive. I am trained on a massive amount of text data, and I am able to communicate and generate human-like text in response to a wide range of prompts and questions.
It’s a 70-qubit quantum computer. It doesn’t have enough memory to break even rudimentary 128-bit encryption.
The algorithm that it executed was also not Shor’s algorithm (the one that could potentially break encryption). The benchmark used is called random circuit sampling, which is just doing a bunch of random quantum operations between pairs of qubits and then reading the output. It’s one of the fastest quantum speedups of any known algorithm.
“128-bit” usually refers to symmetric encryption, which is not broken by Shor’s algorithm. 4096-bit RSA is what Shor’s algorithm needs to break, and it’s going to take a lot more than 70 qubits to do that. Like, two orders of magnitude more.
Alternate headline: Supercomputer makes specially tailored, useless calculations in blink of an eye that would take classical computer rivals 47 years if they tried it for some strange reason
It’s not a good title, but it is an interesting result. A synthetic benchmark is useful in knowing the theoretical maximum speedup that is possible, and whether it is worth exploring further.
It’s really not, though. We know how quantum computation works. We don’t know what it’s capable of in full, but that discussion will happen on proverbial blackboards, not chips.
A paper from researchers at Google published online claims that the company’s latest technology is “beyond the capabilities of existing classical supercomputers”.
Where is the paper? That link points to another news from The Telegraph about oil… WTF?
Based on just the 70 qubits mentioned in the article, and that running Shor’s algorithm on RSA 2048 would require north of 4096 “perfect qubits”, or about a couple dozen million “physical qubits”… it doesn’t sound like they’ve done much.
Quantum computing is mostly a hoax. At least how it is presented to investors and the public. Quantum Computers will maybe be capable of solving a very small set of problems much more efficiently than regular computers, most of these problems aren’t of any parctical importance. It is a massive (financial) bubble that is going to burst soon.
most of these problems aren’t of any parctical importance.
Well sure, but one of them is extremely important. Factoring integers rapidly is very useful, even if it completely destroys one of the most important encryption algorithms.
They can replace them going forward. A major issue is that many governments (and likely other malicious actors) have been hoarding encrypted communication in hopes of accessing it once sufficiently big quantum computer emerges.
Because security is still a big deal. There are post quantum algorithms, but there are similar post quantum algorithms that have been proven to be flawed. It’s important to allow technology like this to mature prior to adoption.
“Hoax” makes it sound like the involved scientists aren’t shouting this from the damn rooftops.
The economically important problems they beat are breaking encryption (actually counterproductive) and simulating other quantum systems (like reacting molecules, which could be useful). There’s other neat tricks they can do but they’re underwhelming to anybody who’s not a technical person, and it’s possible we’ll discover more substantially impactful algorithms but it’s hard so don’t hold your breath.
That’s a bit of a broad strike no? That’s like saying the invention of the modern computing is mostly a “hoax”, all they are capable of doing is adding numbers together faster than a human.
We already know we can transform certain problems that are computationally expensive to be solved by quantum computers. I’m sure more Algorithms can be developed to take advantage of that in the future as well.
“This is a very nice demonstration of quantum advantage. While a great achievement academically, the algorithm used does not really have real world practical applications though."
