And that's if it's goes.

Thio, our friends, Higgs and Company This year's Nobel Prize in physics is about interaction between light and matter.

The Royal Swedish Academy of Sciences has decided to board the 2000 and 12 Nobel Prize in 2620 at last, the phones and the cold, normal superior Paris Franz.

I think you're gonna have to talk to Philip.

Think Phil Phillip said here, right, I'm all right.

And they've just announced the Nobel price on bread Is bread is with me here.

This is, um, ha Rash and Wind Island.

All right, OK, see your life.

Yeah, he's He's happy to chat to where you have to stick to feel because Ed couldn't do it.

What is it?

It's like something to do with trapping light matter.

Wine definitely sounds up.

Phil Streak.

No, you won't.

Really.

It's Peter Kruger on Thomas Fern holds Hello, Brady With me?

I don't know.

You just seem to know about fries.

Has waned.

O right, right.

So that's you here.

It's a surprise because everyone, including myself, I thought it's gonna be Higgs Bos on pigs related science that would get the prize this year.

Surprise, Surprise is not so.

I haven't actually read the citation, but the prizes for Dave Weiland was, uh, in Boulder in Colorado, and Sasha washes in Paris.

And both are pioneers in quantum physics, in each each in their own way.

I know how to control a single particle's quantum particles and actually observed quantum physics in the laboratory, and they've won this case.

It's science charged atoms of various kinds.

And then I'm gonna wash this case.

It's photons.

Particles of light.

What is amazing is that they can actually isolate individual particles from the environment so that they can look at how they behave without the influence, complicated influence they have with the rest of the world.

Why is that difficult?

So it's Have you tried to trap a single Adam?

Well, the first thing is that that Adam's react with other atoms.

They form molecules.

A.

They stick to surfaces, so you basically have to create a system in your laboratory where things isolated.

So one thing we also do in this laboratory is actually build vacuum chambers.

Basically, a vacuum means there's nothing in it, and there is almost nothing in it, but a little bit there is.

And then you can start to think about how to dropped these individual particles because it's slightly different for the for the irons in the photo.

So let's start with the irons.

What they actually, to my knowledge the first time someone saw an individual atoms, wasn't I?

And that was dropped.

You actually need Thio.

Then once you have it in your vacuum chamber, contain it so that it doesn't move too much and hit because the vacuum chamber has a certain size and you want to keep it in the center of it.

The way it's done with irons is actually with electromagnetic fields, so they charge certain electrodes, and in some cases you need static charges and others you need oscillating charges, and that was an ingenious step.

Was actually led to a previous award of the Nobel Prize toe Western Power, who trapped the nine for the first time.

But Dave Wyland and colleagues developed this technique much further, and they managed to not only trap these irons but to actually do things with him.

So then they can look at the quantum physics that goes on in a single particle and one of the features of quantum physics that is difficult.

That made it difficult to observe quantum physics when it was first theoretically developed earlier in the 20th century.

Is that that the quantum system very quickly turns into a classical system that is very similar to the one that you describe that you just you know, Of course, you can grab a piece of something and traffic in your hand by holding it.

In quantum physics, quantum physical systems are different, and the process that turns a quantum system into a classical system is called D coherence.

And to directly observe that was one of the main achievements off.

Actually, both these experimentalists who got the prize now four times to trap four tons is in some ways even more difficult and actually happened later in that sense.

Unlike atoms, Ryan's photons can appear and disappear so they can be created, and that could be, um, annihilated.

This is at least much more difficult for massive particles.

The way the photons are trapped is in the so called cavity, which is nothing more than two mirrors that face each other.

If the mirrors are very good mirrors than the light would be reflected, of course, from mayor Surface, and then it would be reflected from the opposing mirror.

And then it goes back and forth.

If the mirrors are very good, that happens many times in the photon.

Actually survived for a long time in this arrangement, and the trick and how Russia's experiment was to make these mirrors very, very good manners.

And this was done first for for light, off microwave frequency, so we don't usually perceive that as light, but it is just as much electromagnetic waves as as photons.

Optical photons are that way, see, and then more recent experiments.

He also managed to do that, like in the visible range.

While I think what we're witnessing now is actually a time where these things where we go from, just fundamental understanding, too, actually using quantum systems to build devices that are appliances and future devices for building new computers, making new sensors that are more sensitive and have better performance than existing ones.

When the Nobel Prize is given, you'll feel is that good for you?

I would say definitely yes, because it makes the field, in general, more attractive.

People understand more what we're talking about.

We have videos like yours.

Then we have a chance to explain things.

And the media will be full of reports on public.

Generally understandable reports from the field funding agencies will be aware of this.

Colleagues will be aware of this so they will believe us more than what we do Actually makes sense, really?

Spending a lot of time with him, but again, it was because he loved his his group.
