Seminar-Quantum Information (QI)
M
Quantum experiments with entangled photons won the 2022 Nobel Prize in physics
While there are no doubts about the success of quantum mechanics in explaining many of the problems concerning various topics, it is nowadays still an open theory with several challenges. Therefore, the overarching goal of many research groups is to understand how quantum physics can be exploited to develop new technologies that are otherwise impossible. In our seminar, we aim to have a productive discussion time on Quantum Information.
The general picture is as follows:
-We have two sets of papers, Set I and Set II. Our time will also be divided into Part I and Part II.
Part I:
*) I will spend two sessions explaining the basics.
*) We both will read the papers of Set I. However, I will present the papers with details in our third and fourth sessions.
*) I will give a talk about the Set I papers, similar to the talk you should present at the end of the semester.
Part II:
*) After session 3, you should know what paper of set II you want to pick for your presentation.
*) Starting from session 6, you will entirely focus on reading your paper.
*) You start to prepare your essay, which should be 7 to 10 pages. It should be in the style of a scientific paper. If you like, you can use https://www.overleaf.com.
*) You also start preparing your presentation that will be held at the end of the semester (time and date will be decided later). Your talk is planned for one hour, which is 45 minutes for your presentation and 15 minutes for questions. Note that you will present your topic to all seminar participants and the supervisor.

Having access to an entangled state enables quantum information processing tasks that cannot be achieved classically, such as teleportation, quantum computing, quantum error correction, and quantum networks. Many of these applications require generating multi-entangled resource states upfront. However, despite their importance, we are still far from a complete understanding of multipartite entangled quantum states. Among the sets of entangled states, a special class called Absolutely Maximally Entangled (AME) states has attracted the attention of a wide range of quantum applications like many-body teleportation, quantum networks, quantum error correcting codes, etc. By reading these two papers, we will discuss classical and quantum methods for constructing AME states.

Essay
Your essay should be 7 to 10 pages. It should be in the style of a scientific paper. If you like, you can use https://www.overleaf.com and share it with me (z.raissi2@gmail.com) to get comments and feedback before handing in the final version.
Talk
Your talk is planned for 45 minutes, and then we will consider 15 minutes for questions (in total, you will have one hour).
