Google confirms ‘quantum supremacy’ breakthrough


Recommended Posts

Google has officially announced that it’s achieved quantum supremacy in a new article published in the scientific journal Nature. The announcement comes exactly one month after it initially leaked, when Google’s paper was accidentally published early. Now, however, it’s official, meaning the full details of the research are public, and the broader scientific community can fully scrutinize what Google says it’s achieved.

Google says that its 54-qubit Sycamore processor was able to perform a calculation in 200 seconds that would have taken the world’s most powerful supercomputer 10,000 years. That would mean the calculation, which involved generated random numbers, is essentially impossible on a traditional, non-quantum computer.

Possibilities are endless

Full DNA analysis of all Facebook members cross referenced by members that have participated in DNA uploads: 1.00024 minutes
Cure for most common cancers: 2.478 years
Cure for most human virus: 1.85 years

Fact check all political speeches for lies the past 20 years around the globe: ,,,,,, whoops - seems like we need something a bit faster. Seems there are too many lies filling the qubits beyond their capacity

Yep, bingo, this is one of my gravest concerns.  Imagine a super powerful AI with such capabilities, particularly in the hands of anyone who would be willing to leverage such technology for any unethical purpose (not that there really is an ethical purpose when it comes to violating privacy, at least in my opinion).  It does not bode well for the security conscious.

Well, for now that is one area they "claim" that their Quantum Computer cannot do. But I'm betting it's just a matter of time and that the Government and Military is knocking on their doors heavily to get access to that technology


Yep, though they've been claiming for years that the same technology that puts us at risk would also (theoretically) be used to secure us against such threats since they could create protocols based on the same concepts of quantum mechanics meaning that if anyone tried to intercept/observe/obstruct a packet, the act of doing so would change the packet and thus cause a mismatch meaning all communications could be secured this way, however that doesn't address the issue of passwords which are a different matter entirely and are absolutely finite in nature, especially for anything any person could remember (though password managers could remember more difficult ones, but again we're hypothesizing about the kind of machine capable of brute forcing absurdly complex problems in a fraction of the time it would take a normal super computer which is the attraction of such tech in the first place).

Yep, particularly since Google has been known to exaggerate a bit when it comes to their tech and accomplishments.  For example, the claims they've made with Stadia that still haven't panned out and in fact have been found quite wanting with regards to becoming a globally accessible cloud gaming platform with 0 latency.  It turns out that even with all of their money and all of their servers, Google is still subject to the same laws of physics and limitations of network infrastructural capabilities as everyone else who has tried or thought of trying such a venture.  The reality is that most people lack an internet connection fast enough for such technology to work (especially in the US where much of the web is still on copper rather than fiber).
