Thank you!

I would love to know as well!

Ah, my bad then.

... what you said is correct, but that's superposition, not entanglement. Entanglement is when you create a product state of several qubits that cannot be decomposed into a tensor product of basic states (a single proton/photon/whatever).

Oh yeah, that. My bad, mixed 'em up.

The original algorithm doesn't use entanglement, though! Just the fact that measurements can change the state. You can pick an axis to measure a quantum state in. If you pick two axes that are diagonal to each other, measuring a state in the "wrong" axis can give a random result (the first time), whereas the "right" one always gives the original data.

So the trick is to have the sender encode their bits into a randomly-picked axis per bit (the quantum states), send the states over, and then the receiver decodes them along a random axis as well. On average, half the axes will match up and those bits will correspond. The other bits are junk (random). They then tell each other the random axes they picked, which identifies the right bits!

They can compare a certain amount of their "correct" bits: if there's an eavesdropper, they must have measured in the wrong state half the time (on average). Measurement changes the state into its own axis, so the receiver gets a random bit instead of the right one half the time. 25% of the time, the bits mismatch, when they should always correspond.

You can have post-quantum cryptography using classical computation, though

("Simply" pick a problem with no quantum acceleration. I think Elliptic Curves Cryptography works, but I'm not an expert)

"The transgender topic" is already weird as a statement (kinda like "the gay agenda", it comes off as only considering it as a political statement?), and "clearly promoted by the bourgeoisie" implies it's bad.

"As far as [...] lgbt flags on government buildings": it's... not far at all? Again, weird statement.

"Biological male" is both wrong for the boxer (she's cis) and generally used for transphobia (trans women on HRT aren't biological males by any reasonable definition). It's also generally conspiratorial.

Overall it's not explicitly transphobic or bad to me, but it shows at minimum a very misinformed perspective.

But there's no "biological" reason for that. In the same way, skirts/dresses being for women and suits/ties being for men, leg hair, haircuts, voice, mannerisms, emotional availability, all get tied one gender or another.

We, in our society, have associated some properties to one of two genders. Some of these properties tend to be associated to one sex (sex being a more "biological" thing (but still not binary or unchangeable!)), but many of them are just expectations we put upon people. This is what "gender is a social construct" means; that the general understanding and intuition about gender is constructed by the society in which we live. Different societies may have more than 2 genders or completely different sets of associations.

Unfortunately these categorizations are bad for a significant portion of the population, including trans people, gender non-confirming people, but even cishet people; how many times have you heard of some act making you "not a real man" (eg crying for a movie)?

Wow, I didn't know that! That's absolutely wild

.... The root of the thread you're replying's main body is stuff JSO has actually achieved.

Yeah fair enough, I didn't mean to contradict you, more add on to your comment

I'm assuming this is referring to JSO.

Beginning on 1 April, they carried out England-wide blockades of ten critical oil facilities, intending to cut off the supply of petrol to South East England.[33][34][35]

On 26 August, the group blocked seven petrol stations in Central London and vandalised fuel pumps. Forty-three people around London were arrested on suspicion of criminal damage.

On 20 June, the protestors spray painted private jets at a private airfield at Stansted Airport. The group had been targeting a jet belonging to singer Taylor Swift, but could not locate it.[140]

Yes, a lot of their protests are "awareness" stuff (basically none of which do actual damage. Unlike oil, actually!). No, it's not just that. The UK isn't an active warzone so bombing stuff is slightly more difficult to justify.
