What do you think about what I think about quantum physics?

there neither is now, nor was there then a better form that cannot be broken by quantum computers. We are still encrypting everything with algorithms that will be smashed when a sufficiently capable quantum computer becomes available.

We are developing alternatives, as linked above but they are not yet ready for commercial implementation.
Note that those are alternatives for public key encryption, not symmetric encryption or hashing which are generally much more resistant to quantum attacks (so far...) If you're deciding to use public key then you should know that the security horizon is essentially 'how long before the opponent gets hold of a sufficiently powerful quantum computer' and take an informed guess at how long that might be - much like the informed guess at whether someone will find a weakness that will speed up the process on a conventional computer, and by how much. And how much more affordable conventional compute power will become. If you think that horizon is too short you look at the alternatives and do some risk analysis - sticking with public key may still be the least-worst option.
 
I've totally been avoiding this thread...

I did see some posts. One poster mentioned that 3 scientists together won a Nobel Piece Prize for their work in "Quantum Mechanics", which I looked in to. I was considering elaborating on my anec-data regarding the "mechanical" (ie practical) vs "possible" (eg theoretical) implications of their work...
Meanwhile, Sabine posted about it too. I can't remember if that was that video or her very next video (This Paper Might Change How We See Gravity) that basically "threw a spanner in my works".
*(and just looking at the thumbnail of that second video now, I think she concluded that whilst the paper was legit, that it was actually only in-fact a slight "proof" beyond previous ones. but something mentioned was something...)

I saw another poster mention "why post this on an audio forum". Well: 1) it's fun; 2) there's PhD Physists posting here; 3) Sabine criticises "academic physics" as (tldr-imo) "chasing the money", which whilst I'm not 100% sure about, I can 100% get behind from a human/capitalist/communist perspective (everyone is implicated. that's equality!); 4) One aspect of her criticisms is that everyone is trying to "tweak existing theories" rather than consider other options... 5) My actual job is "structural designer", but not "structural engineer". And so whilst I don't know the calcs to do, I am particularly good at "designing"... (aka imagining b-s)
Edit: 6) Now that the internet is known to be "polluted" by "AI" posts/bots/etc, my rambilngs will likely be curated as "authentic new content" (which they are) — and thus, my idea's will liekly have an effective-effect on the future. #winning

And that last comment also addresses the person that said "where's the calcs".

But back to the "why post this on an audio forum" point – I've actually learned a "deeper" understanding of everything whilst being on this forum, and that is because of "waves". It seems those pesky waves are everywhere! First you ask: why doesn't my sound system sound awesome? Maybe it's the DAC, maybe it's the AMP, maybe it's the SPEAKER, maybe it's the ROOM? Go to ASR forum, get REW... discover modes... interference... impulses... nekminnit I'm reading about 0,0,0 room nodes. MFW! It's all waves!

I'm very much rambling again. Anyway, Sabines recent video titled How Signals Can Go Faster Than Light had me scratching my head in a whole new way...

PS1: The Big Misconception About Electricity. That video "broke" a part of me. Not that it made me "mis-understand" what I knew about electricity, but that it made me realise that I only had a "practical" understanding of electricity. And so when I then considered the fact that I work with Engineers that know nothing about "new advancements in Engineering", whilst meanwhile I know "more than nothing" about them, then it quickly becomes apparent that "university educated engineers" are also just "mechanics" in a way – they too are just people applying the "processes" that they were taught to apply.
PS2: Something Strange Happens When You Trust Quantum Mechanics. I had the feeling all throughout the video that many things were "wave cancellation" in the same style as DBA (double bass array). And then near the end of the video, the bloke literally did an "experiment" showing that exact cancellation via light-waves (:head-explode-emoji:)
 
I occasionally watch videos regarding physics, but I try not to dwell on the possibilities too much (coz I've got other things to waste time on). However, I had what seems to be a decent thought the other day, and so perhaps some of you will enjoy making comment? (PS: this post is 0% ChatGPT)

So the other day I was watching the video "Will scientists ever agree on quantum? | Sabine Hossenfelder and Matt O'Dowd FULL TALK", and during the discussion about entanglement and "spooky action at a distance" and all that, I think it was O'Dowd that said something like "it's kind of like the particle knows the outcome of it's measurement at the time of its creation, which means it knows what the future will be"...

And at that point, I had the thought that it's not the "outcome" that needs to be known at the moment of creation, but (in computing terms) actually just the "get_outcome_function" that needs to be passed along with the particle, and then the "outcome" (result) can be computed "lazily" if/when it is needed using the "local state" as a variable.

But if that were the case, then the 2 entangled particles could end up with the same computed outcome, which would be "wrong", and hence the "spooky action" comes in to the mix. But sticking with the lazy_function train of thought, then it's trivial for each function/particle to have a reference/pointer to the other, so that at the time it needs it needs to get its outcome, it can first check if the other particle has already calculated its outcome, and return the opposite if so.

And so there's still the problem regarding the "speed of light" and how that information gets transferred, but if you consider at this point the "simulated universe" theory, then that's a trivial problem; because the information doesn't have to travel particle-to-particle "through" the simulation, but it can simply be transmitted through the "server". For an analogy, consider a computer a computer game that runs at 60fps (60Hz), but that is running on a computer operating at ~4GHz. Thus within 1 "tick" of the simulation, there is plenty of time to transfer/compute that information (and in the "universe simulation", 1 tick would be 1 unit of light-speed-time)

Now I normally don't bother considering the "simulation" theory much, because it's kind of irrelevant in the same way as considering if the universe was created by God or similar. But in regards to this quantum discussion, it seems to "fit nicely". That's because there is also the aspect of quantum physics regarding "many possible outcomes" and "wave functions" etc. And so if you ponder why all these "possibilities" would be "computed" and many discarded, then there's 2 rather simple answers why: 1) It might just be "branch prediction" of the CPU running the simulation; or 2) the "simulator" might not be computationally constrained, but I/O constrained.

So continuing with #2, and in regards to "inefficient" code: if particle_1 needed to get its result, it would have to check if particle_2 had a result, and if not, then calculate and return a result. But what if that "request" between particles was "slow", and it just so happens that you have tons of computing power to spare? Then it would make sense for particle_1 to send of the request to particle_2, and in the mean time, just go ahead and calculate all possible outcomes. That way, once particle_2 has responded, then particle_1 is "ready to go". In programming terms, this is basic sync/blocking vs async style programming, and it's exactly what is happening in your web browser right now.

But why would there be an "I/O constraint"? Well when you consider our computers, there is always a "penalty" to transfer data between 2 different places, like CPU cache to RAM, or RAM to HDD, or from the "cloud" versus a thumb-drive, etc. This implies that there is computation happening at different "places". ..

Now I'm "forking" my own post away from quantum towards a previous "thought" I've had involving "dark matter" — but I'm just going to give the jist: If each galaxy is it's own "simulation", then they may be subordinate to a master/universe simulator. If this is the case, and one universe needed "some" information from another (ie, to render some stars), then you wouldn't want to transfer the "full state" of 1 universe to another, and thus you would send something "simpler" (like what voxels are, and like how game engines take "shortcuts" regarding "global illumination"/lighting). And to jist-the-jist: if we measure universes and they behave like they have more mass than it appears they do (ie, have dark matter), then what if that is simply the difference between `count_object_memory_use(universe_2.screenshot)` and `universe_2.memory_in_use`, and the reported memory isn't "accurate" because it is the memory in use by all objects of the simulation as opposed to objects IN the simulation (i'm implying that it might include "ghost objects", ie objects that have been deleted but not yet "garbage collected").

And my fork doesn't stop there, because black holes can be explained similary. Something about them that stood out to me is the "fact" the event horizon "stores" the "data" of everything that passes it. In short, perhaps: 1) black holes are the "recycle bin", whereby the objects are deleted, but still actually there; OR 2) like when you actually delete a file on your computer, it's probably not "physically" deleted from the harddrive, but it's space just labelled as "free". Thus, the data is still technically there, but not taking up any space...

And now to fork the discussion way back: perhaps it doesn't have to be a "simulation" for the data to transfer at another "level", because can't it just happen in a higher dimension?
Edit: And what if the "deleted" data still exists in that higher dimension (like bits still physically recorded on a harddrive), and thus have "some effect" (ie, they are the dark matter. and how they cause effects is akin to "buffer overflows").

Anyway, please enjoy my ramblings.

Probably you all ready aware that while you were writing above opening remarks your laptop’s SSD or phone flash memory was probably doing some quantum tunneling of its own.

Flash memory stores data by trapping electrons in a tiny floating-gate trap. Classically they shouldn’t escape, but thanks to their wavefunction (beeing in a superposition), they tunnel right through the barrier. That’s literally how the cells get programmed and erased.
So while you were thinking about spooky action, your storage was already quietly doing the spooky stuff.:cool:

I looked into Quantum Physics, but that changed it... :D

I did notive however that they appear to have re-invented the Aether, another thing that disagreed with the Einstein viewpoint.
 
Wandering who ?
