For the first time, researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.

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.

And here’s is the published paper.

    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.
