## ESQuisses Summer School

We are organizing a summer school during the week July 4th – 8th 2022, on the island of Porquerolles (France). The topics of the lectures are varied, and include quantum machine learning, quantum trajectories and feedback, random unitary circuits, and quantum cellular automata. Registrations are open, deadline April 30th 2022. The

## SudoQ – a quantum variant of the popular game

Together with Jordi Pillet, who was doing his master’s internship last year at the LPT, we have a new paper, introducing a quantum version of the Sudoku game. Sudoku puzzles can now be found in many newspapers and have become part of the popular culture. Numerous mathematical results have been

## RTNI – A symbolic integrator for Haar-random tensor networks

Together with Motohisa Fukuda and Robert König we have a new paper (and some code!) RTNI – A symbolic integrator for Haar-random tensor networks. This is a very unusual paper for me: the main goal here is not to prove theorems but to introduce a piece of software we developed:

## Random quantum measurements

We have a new paper together with Teiko Heinosaari and Maria Anastasia Jivulescu: Random positive operator valued measures. We introduce and analyze different models of random quantum measurements (POVMs). We prove that two very natural procedures for generating random POVMs are actually identical and then we analyze in detail the

## Master’s internship

If you are looking for an internship for your Master’s studies and would like to work with me on block random matrices, non-commutative Sinkhorn scaling algorithms, quantum incompatibility, random density matrices, or any other topic in random matrix theory or quantum information theory, write me an email. There is the

## The joint distribution of marginals of multipartite random quantum states

Together with Stephane Dartois and Luca Lionni, we have a new preprint on the arXiv, On the joint distribution of the marginals of multipartite random quantum states. The paper is about the joint distribution of the set of (twisted) marginals of random multipartite quantum states. We study mainly random Wishart

## Counting meanders

We have, with Moto Fukuda, a new paper on the arXiv, Enumerating meandric systems with large number of components, which deals with the enumeration of meandric systems. In combinatorics, a meander on $2n$ points is a closed, self-avoiding plane curve, which intersects a given line $2n$ times. Below, the meanders
