You know that this group will end on Thursday and there is only one course, so we basically

end around the half past ten, except that we thought that it would be nice to have a part

of a general discussion. So if you have ideas to discuss or if you want to have ideas to

discuss, think about it. So Florian, what do you think?

Swati will help me. We will have a general brainstorming and outlook session on optomechanics.

Okay. And then we have Dirk and Joachim, autism for last night.

Okay. So as I also just added on the scale of the seminar, by Nicolas El-Khizam from Vienna,

on the macro project, you know the space orientation to take that.

So that the last student's talk will be on Wednesday at 4. Okay. So introducing the speaker

will be very easy today because I've known Olivier for a long time. So today he's been

a PhD student and I work in Paris. Then he went to work with Tobias in Garcher.

I think you never heard of him. And as I said, he was a PhD student at Garcher.

He got a senior exhibition in the third or he started in the home group on the

10th of October. Okay. So. Actually, I have to feed the kids about the room.

But I know you'll be in the room. Okay. You have the room and I have the room.

Okay. Thank you. So thank you for having me and for giving me the opportunity to present

what we are doing in the manner of this lecture. So this item is called quantum mechanics.

The goal is to cover the mechanical circuit of the quantum system, to cover the system,

to cover the quantum mechanics. In our case, it will be a thing with the LED tech and it's

similar to what I have with you and what a few of you are doing with our team.

We are investigating the many different things. The objective for the context is to make

the right one, yes. So by using the... So there was the objective for a short time

and it was to put the small state for the... And it was a difficult task because you have

to first reach the cellular to Garcher, which is a little bit higher. And second, you have

to be able to observe the system in its small state. It means that I need extremely large

positions and things. It was very difficult and by using the two of the...

So, quickly, the system you want to investigate, the cellular you want to investigate to light

field, and quickly into locating QNM sensitivity, you can first realize the

ultra-sensitive display system. So, furthermore, you can use back-action as a measurement.

You have to be cool-down the digital oscillator and other groups have been working on that.

And in the few years, in 2010 or 2011, in them, a few groups are really approaching the

wrong state or are in the wrong state of the system. And the goal for experiment is to

try to go in there and to try to do something else than the wrong state. And in order to

do that, so that is to try to create non-classical states of motion. And then, I need, for

example, to... No, for example, this is non-classical states, it's not a problem for us.

First, we have to replace the number of free states or something like that. And the strategy

we have is to place the interface from the digital system as an external system, in fact,

to transfer the computer or the system into the outside. By doing so, we define what is

called the new brain-improved system. And the idea of what we are going to do now is to

create such a system which can measure and reactivate both components of the system,

as I told you, in the previous lecture on the few keys. And for the one of the systems,

we have an interesting dynamics, the dynamics of the speed-geek and the dynamics of these

different receptors, developed on a more competitive time-scale, in order to bring all the measurement

theory into this system and try to model the signature in the image. The motivation is

to try to model the content signature, which is the content signature of the object.

It is a task-connection with content-information processing, with also the development that

is going on, causing the variation of the force sensitivity in order to see the way

we are coping with this system. More fundamentally, it is interesting because this type of interaction

will produce this kind of screen, which has been done in the QED with photons and photons.

And that is something very interesting, and I will try to show you an analogy.
