Adaptive optical imaging with entangled photons. (https://pubmed.ncbi.nlm.nih.gov/38452085/)

These scientists wanted to make pictures of really tiny things, like cells, look even clearer. They used a special technology called adaptive optics, which helps make the pictures sharper by fixing any blurriness.

But, in some microscopes, they couldn't use the regular way of adaptive optics because there was no bright star to guide them, like in outer space. So, they came up with a new idea! Instead of using a star, they used something called entangled photons, which are like twins that always act the same way.

With this new method, they were able to fix the blurriness in the pictures without needing a guide star. They tested it by taking pictures of tiny living things, and it worked really well, especially when the pictures were a bit out of focus.

This new way of adaptive optics could help scientists see tiny things even better in the future, and might even lead to new kinds of microscopes that use quantum technology!
