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.

    Actually, I kind of get what they are saying. In order to entangle two things, the two things need to already be aware of the space between themselves in order to entangle.

    This is is kind of stupid though, because it could always be the path of least resistance, UNLESS you can observe one end having knowledge of the other and making an informed choice to somehow join it’s entanglement.

      I think when you observe quantum stuff it stops being quantum immediately and they found a way to keep it from decaying to preserve information for longer?

      It’s by looking at the shape of the quantum stuff that they can preserve information without causing a break in entanglement since it’s not direct observation.

      I wonder what this will really mean for humanity other than complicated papers.
