> Literally just different frequencies.

There are many more changes than that. But it’s true that 5G NR uses the same overall modulation scheme as LTE.

> Why on earth would they?

Right, but they are not currently on earth, so…

> Grover's algorithm more than "halves" the difficulty of AES, it square roots it.

Yes, but unfortunately it also makes it impossible to run the algorithm in parallel, making it more or less useless in practice.

AES isn't really susceptible to quantum attacks except with Grover's algorithm, which isn't effective because it can't parallelise very well. So I don't know where that 6600 number comes from.

Also, note that that would be error corrected qubits, which these chips don't have.

> Maybe the US government already has the capability to crack SHA256 hashing and AES encryption using quantum computing accelerators. This could be old declassified technology.

That's extremely unlikely to be the case. Especially since quantum computers don't provide any useful speedup for those applications.

> Qubits do not store any more information than bits

How don't they, though, when each qubit requires a complex number (with modulus 1) to describe? Even if this information isn't directly available to measurement.

The are good for solving problems in a class called BQP. There is a list here: https://cstheory.stackexchange.com/questions/31139/problems-in-bqp-but-conjectured-to-be-outside-p

Yeah, BQP (the problem class solved by quantum computers) is generally believed to be disjunct from NPC.

> Simulations and cryptography mainly. It might have potential to reduce time complexity of algorithms from exponential to quasi exponential or even polynomial time (n-bit encryption).

Yeah, so cryptanalysis, not cryptography (encryption, decryption, signing, verifying) so much. Cryptanalysis is however still completely infeasible on today's quantum computers.

> The Australian government (eSafety Commissioner) is already demanding that companies implement encryption backdoors and mandatory proactive scanning for anything potentially “illegal”. Source

I don’t really see where your source specifically demands that they implement encryption backdoors. Of course that would be one way to implement what they seek.

> Except the courts aren’t just and their intentions aren’t pure.

Is that a fact or your opinion? Also, in what country?

Maybe I’m just used to a different kind of society (Denmark), but I don’t really see the problem with that?

> Assuming they didn’t do anything incorrectly. Like secretly having a second password for customer support, or for law enforcement requests.

But if that’s secret and not leaked, an attacker wouldn’t be better off.

> Well, if you want to be pedantic, velocity is a rate too, is it not?

Yes, but expansion is velocity over distance, so it’s not units of velocity and thus isn’t c or below or above c.

> Suffice it to say, the size of the universe expanded from the planck length to a factor on the order of 1028 in an extremely short amount of time

The observable universe. Maybe, yes, but that doesn’t make it expand at a certain velocity unless you measure over a certain distance. And at this distance, relative velocity wouldn’t be well defined due to the curvature of spacetime, and wouldn’t be constrained to c anyway.

See first answer to this: https://physics.stackexchange.com/questions/400457/what-does-general-relativity-say-about-the-relative-velocities-of-objects-that-a

Yes, that’s always possible, although I’d say that exploits this serious (zero interaction) are quite rare. One click exploits are already much less powerful for targeted attacks, although can work pretty well for broad attacks.

I’m curious, why would you think it wouldn’t be closed after this long? Exploits like that are generally fixed as soon as possible.

> The universe is not expanding faster than c. In the very early universe, this was true,

What’s that supposed to mean? Expansion is a rate, not a velocity. Relative velocity is only locally well-defined.

How did the early universe expand at more than c in any way that doesn’t just as well apply now, over enough distance?

Myeah, but then the problem is that such expansions would often be oversimplified.

> it’s now so filled with ads and garbage that it’s almost functionally useless.

I think that's a huge exaggeration. I use it several times each day, and mostly find what I look for. Ad supported search results are at the top and marked as such.

> This completely undermines their claim that they would never abuse or exploit user data.

Sort of? But they allege that some employees improperly accessed this data. There is no way to completely prevent that in any company. Some people always need such access, in order to do their jobs.

> If ByteDance (TikTok) can do it

You mean access the user data for their own users? Yeah... any company can do that. Not all employees can, but some can.

Who did? Facebook didn't make money from this; the data was obtained by CA freely, on the app platform.

Yeah, that was an amazing exploit. Long closed now, of course, but still.

Misleading headline. ByteDance didn't confirm that "it" did this, but rather than some now fired employees did.
