No, that's Zelda.
In all seriousness, here's the story.

Scientists unveil the first-ever image of quantum entanglement

For the first time ever, physicists have managed to take a photo of a strong form of quantum entanglement called Bell entanglement—capturing visual evidence of an elusive phenomenon which a baffled Albert Einstein once called 'spooky action at a distance'.

 
Two particles which interact with each other—like two photons passing through a beam splitter, for example—can sometimes remain connected, instantaneously sharing their physical states no matter how great the distance which separates them. This connection is known as quantum entanglement, and it underpins the field of quantum mechanics.

And remember my friend, future events such as these will affect you in the future.

I am not certain where Posthuman found the story, but here is what I found:

Introduction:

 

 

(Phys.Org) For the first time ever, physicists have managed to take a photo of a strong form of quantum entanglement called Bell entanglement—capturing visual evidence of an elusive phenomenon which a baffled Albert Einstein once called 'spooky action at a distance'.

 

Two particles which interact with each other—like two photons passing through a beam splitter, for example—can sometimes remain connected, instantaneously sharing their physical states no matter how great the distance which separates them. This connection is known as quantum entanglement, and it underpins the field of quantum mechanics.

Einstein thought quantum mechanics was 'spooky' because of the instantaneousness of the apparent remote interaction between two entangled particles, which seemed incompatible with elements of his special theory of relativity.

 

Later, Sir John Bell formalised this concept of nonlocal interaction describing a strong form of entanglement exhibiting this spookiness. Today, while Bell entanglement is being harnessed in practical applications like quantum computing and cryptography, it has never been captured in a single image.

 

In a paper published today in the journal Science Advances, a team of physicists from the University of Glasgow describe how they have made Einstein's spookiness visible in an image for the first time.

Rats.  Yuli Ban beat me to it.

What applications do you think it will have ?

Probably very few applications as things stand.

 

Generating quantum entangled particles is very difficult, and even if successful it would (as I understand things) be impossible to transmit useful information faster than the speed of light using these methods.

 

A lot of pop-science articles seem to imply that information can be transferred using quantum entanglement though because FTL communication would be a huge deal, but most of the time the scientists behind whatever breakthrough are clear that this is not possible. 

 

I think there are some uses for electron microscopes, because it makes it twice as efficient to measure particles, because each one you measure also tells you key info about it's entangled partner. 

 

There are also theories that quantum entanglement is a key part of biological systems including humans.
