From NPR News, this is Invisibilia Amalese Speagle,

and I'm Lulu Miller, one day last summer,

because we wanted to see something truly magical.

Lulu and I found ourselves standing in front of a huge table,

covered in lasers and mirrors,

while a very nervous physicist hovered nearby.

I try not to bump anything here.

The nervous physicist, and our guide for today,

was a grad student from the University of Maryland

named David Huckle.

It doesn't look like these things do anything,

but I promise you all of the pieces on this table are important.

And David had brought us to the table

because he wanted to use the many lasers and mirrors

to try to perform something called quantum entanglement.

Yeah.

He was going to try to take two separate atoms

and using his laser, turn them into the same thing.

At the simplest level entanglement,

it's just the idea that two things

that are separated in space can still be the same thing.

That's Jeff Brumfield, the physics guy at NPR,
