Rules:

1. Be civil

Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.

Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.

3. No bots, spam or self-promotion.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.

4. Post titles should be the same as the article used as source.

Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.

5. Only recent news is allowed.

Posts must be news from the most recent 30 days.

6. All posts must be news articles.

No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.

7. No duplicate posts.

If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

8. Misinformation is prohibited.

Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.

9. No link shorteners.

The auto mod will contact you if a link shortener is detected, please delete your post if they are right.

10. Don't copy entire article in your post body

For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Researchers demonstrate that quantum entanglement and topology are inextricably linked (phys.org)

The team hopes that this might become a powerful tool that paves the way for new quantum communication protocols that use topology as an alphabet for quantum information processing across entanglement-based channels.

The findings reported in the article are crucial because researchers have grappled for decades with developing techniques to preserve entangled states. The fact that topology remains intact even as entanglement decays suggests a potentially new encoding mechanism that utilizes entanglement, even in scenarios with minimal entanglement where traditional encoding protocols would fail.

Edit: Here is the quoted article link.

And here's is the published paper.

I understood all of these things

I think it's really neat when I read some obscure or esoteric science discovery and feel like I understand it. Although I know I would need years of study to maybe even begin to be able to understand how to discover that truth.

I didn't understand it even slightly, oh well. I couldn't even tell whether this was an experimental result or just a theoretical one. That's just from the phys.org post though. I haven't looked at the Bature article.

Without looking this up first, I think topology is a mathematics..mathematica..a field of mathematics that makes proofs of topologies in nature. Like what is the mathematical proof of how a knot can be removed from something without untying it. Hang on let me look this up...

Okay here: Topology is the study of shapes and spaces, focusing on properties that are unchanged by continuous transformations like stretching or bending, without tearing or gluing. It's used to understand and classify various mathematical, physical, and computational phenomena.

So topology shows how a coffee cup is a misshapen donut, or a human is donut (with center hole from mouth to...butthole) and now, how quantum entangled particles can be perturbed (messed with) and still maintain coherence (not break and still be an entangled pair).

Here's the coffee cup donut:

So it sounds like they are using topology to classify entangled quantum 'shapes?' which will allow them to better understand and manipulate quantum entangled states? And so far the math is holding up?

I love this stuff. Like how the math showed that black holes should exist before we found any. It's like frickin magic man. Like wizards reading the magic symbols to unlock the secret fabric of reality, but like, for real.

I find topology fascinating. I'd love to learn more about it but it quickly goes above my pay grade.
