"By shining a laser pulse sequence inspired by the Fibonacci numbers at atoms inside a quantum computer"
Inspired by Fibonacci numbers? At atoms inside a computer?
Try harder.
Perhaps I'm just not smart enough to understand it but it seems they're just firing lasers in a specific sequence, then click their heals 3 times , think of Kansas and for quantum/higher dimensions/pentose tiles/fibonnaci other theoretical buzzword bingo reasons that means it looks like the crystals could have 2 time dimensions if you squint at them in the right way.

If I understood correctly, this extra "dimension" is a bit like treating alternating current as a two-dimensional vector spinning around. The extra dimension isn't really there, but it makes things much easier mathematically.
-
It’s all fun and games till someone busts out the phasors.
-
left, right, up, down, forward, backward, tilt, jaw, pitch (and whatever their both sides are called). woah! 6 dimensions of.. space? oh, quarks dont really have colour, it just make things much easier mathematically.
-
-
We could probably understand the extra time dimension if we weren't all educated stupid.
-
Extra time dimensions would make laws of physics meaningless [wikipedia.org], so I'm not sure there'd be anything to understand.
-
Well, what the popular discussion actually says is that the laser pulses have the time symmetry similar to projecting two dimensions onto one. It's like saying a (two-dimensional) drawing of a cube has three dimensions. No, it doesn't actually have three dimensions; it's just calculated from a projection of three dimensions.
(the phasor example above is right on).
-
galileo made flat earth useless. geeks work against string theory is the same thing as the church working against science.
-
but a cube is just a 3d square? and a square is just a 2d point? just like division is just minus minused. and multiplication is plus plused. do they exist? and minus is just plus reversed. does minus exist? if you take two two dimensional drawings of a cube drawned from different angels, and use 3d glasses, is it a 3d object then? wow, does anyone even mention stephen hawking here? go back to writing ½D code of mediocre microsoft copies. autodidacts are great.
-
No, you're wrong.
A square is a 2D line. A point is a 0D line.

everyone calls einstein a douchebag. but he spent his later days trying to come up, with what would be the string theory. he researched a lot into multi-dimensions. the simplest string theory is 11 dimensions, with 2 dimensions of time. its sad people dont even understand quantum physics. slashdot reminds me of the registry. just a bunch of drunk englishmen in pubs, trying to be funny. i guess legalising weed wasnt such a good idea.
-
Realistically, almost no one calls Einstein a douchebag.
-
Well, are we talking about Special Realistically or just the standard model of Realistically?
-
No, just general realistically.

time before: only forwards, at a constant speed (1/4 dimension?). time as 1/2 dimension: can go forward, at different speeds. time as 1 dimension: can go forward and backward, and at different speeds. time as 2 dimensions: you can redo a change you didnt like (as seen in CERNs photon experiments). time as 3 dimensions: ?? ?? ?? ?? ??. if time is a dimension, can we photograph it? (weve got cameras to photograph gravitywaves, why not?). time as 0 dimensions: motion is only the speed at which atoms move aroun

Multidimensional time has been useful in many SF stories and films and the net has several contributions of personal experiences of people that moved in a different time line. I regarded this as amusing nonsense until I had a couple of very brief experiences in what might be explained as an adjacent time line so I am not sure anymore about the nature of our time-space.

Occam's Razor says that you having a temporary bout of insanity is a vastly more likely explanation than a profound misunderstanding of laws of physics on humanity's part.
-
In my long life (I am 96) my occasional bouts are with sanity since, like most of the current world now facing extinction, insanity is my only recourse to retain some grasp of current reality.
-
to say it once again: have you ever drunk a beer? "reality" sure seemed weird then, huh? its a shame normies act like they dont know anything. what would you call that? normopathy? yep.
-
I'd think that the simplest explanation would be a vivid dream.
-
-
...because it's convenient science-sounding jargon that gives a pretext of "this is real science that you just don't understand" to make plots work.
-
There was no intended confusion in the film "Back To The Future", merely an attempt to play with a far fetched idea where a two dimensional time presented a surface instead of a line to permit multiple time lines and solidify the notion of probability.
-
-
if youve ever had a best friend, or been in love, youd understand. you know when people argue about seemingly meaningless things, because each side interprets things in polarity? paralell universes. i guess normies have never drank a beer.
-
Nevertheless, multiple universes are not totally dismissed, even within accepted science and fantasy speculations on realities is a fundamental element of all exploratory attempts to make sense of perceptions. Science is no different from any of the other arts to grapple with confusion and solve puzzles, even if that solution has a useful bu temporary utility.That one universe might also offer multiple branching solutions is not a particularly radical concept.

i have an older relative who does research on multi-dimensionality. not sure if i would want to meet him. hed probably not reveal anything. i know people who can see time. (they download your fate from the akashic library. [uhm is the powerword for the third transcendental chakra. you know when people try to remember what they were gonna say? they say.. uhm.. a lot] whatever you say to them, they see it from a 100 angles. you know how some people, always "freeze" when you talk to them? they see what you say

Thank you for giving me a glimpse of your universe, as well stocked with mysteries of rather different qualities than those that inhabit my own varieties of monsters and mice. We each devise a different set of tools to deal with our own menageries and some can be succumbed to eat out of our hand while others find our fingers delicious.

The question is whether it is better explained by a (temporary) malfunction of the brain.
Our brains, our perception, is full of flaws, and we regularly project the results of these flaws onto the world.

As someone has already commented, the article does not say anything about time-dimension at all, much less claim two of them.
On the other hand, many fundamental properties are synonymous to symmetries (as least the math works out the same and the symmetries has simpler math). I don't work in this stuff, but the cited reason: error control is related to the time-dimension is discussed (if for no other reason that errors happen over time). The paper probably had this in mind, but *wisely* skipped mentionin -
"This arrangement, just like a quasicrystal, is ordered without repeating. And, akin to a quasicrystal, it's a 2D pattern squashed into a single dimension. That dimensional flattening theoretically results in two time symmetries instead of just one: The system essentially gets a bonus symmetry from a nonexistent extra time dimension."
The title and preface are indeed pretty bad, and try to make this into something it isn't, but the rest of the article is IMO better, and does give an idea of what's going on.
