MEMO Student Chapter

The Marseile ElectroMagnetism and Optics (MEMO) student association was created recently with the aim of organizing events related to electromagnetic and optical science. In particular, we aim to create and strengthen links between young scientists studying towards a Bachelor, Master, or Ph.D. degree and researchers at either academia or at industry. We are also be engaged in outreach activities aimed towards the general public.
At the moment, we are mainly a group of PhD students based at the Fresnel Institute. However, our aim is to become an association grouping students of many levels from many institutes, schools and universities in Marseille.

Oouu. I would like to ask a question. I know this recording is almost 2 years old so I don't know if I'd get a response. Without diving into the maths I would just like to know how the interplay between distinguishability and indistinguishability of the discarded idler, plays a roll in producing the image. Like the theory behind it. Thank you @andres vega

What is the cost of the pin hole and how hard is it to align with the blue LED? Have you published your reconstruction software?

Interesting presentation , thank you. Question: in the first experiment (before 19:00), the red photon coming from the top goes through the sample and onto the dichroic filter and into the non-linear crystal but then gets deflected out. What's the purpose of sending it through the bottom crystal? It's not supposed to produce any extra photons as I guess only the pump photon can. So does it have a role in the outcome?

Hi, thanks for the question. The purpose of sending the red photon of the first source (idler A) through the bottom crystal is to introduce indistinguishability between the idler photons that could come out of the bottom crystal. If the paths of the idlers are aligned, there is no way to know from which crystal it was produced, this means that the states are interfering with each other. This is the key concept of the scheme. The object introduces an interplay between distinguishability and indistinguishability of the red photons, which combined with the fact that there these are tightly correlated to the green photons (signal photons), allows the green photons to produce an image of the object, non-locally. Best, Andres Vega

@@castaway1889 do you have a paper that goes with the presentation? It's better I read it to get the details. Thanks
