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 … Continue reading
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 points is a closed, selfavoiding plane curve, which … Continue reading
Bipartite unitary operators and quantum Latin squares
Tristan Benoist and I have just arXived our paper On bipartite unitary matrices generating subalgebrapreserving quantum operations. We characterize the set of bipartite unitary operators which give quantum operations preserving some subalgebra of the state space, independently of the state … Continue reading

Seoul lectures on some applications of random matrices to quantum information theory
Last week, at the invitation of Hun Hee Lee, I gave a series of three lectures on some applications of random matrix theory to problems in quantum information theory. The notes are available here. After discussing the Marchenko–Pastur theorem, I … Continue reading
Linear Matrix Inequalities, Semidefinite Programming and Quantum Information Theory, Toulouse 1822 January 2016
I am organizing a weeklong workshop in Toulouse, on topics of optimization problems in quantum information theory. Besides the usual research talks, there will be lectures by Aram Harrow, Jean Bernard Lasserre and Mihai Putinar on the topics of the … Continue reading

Random subspaces of a tensor product (II)
In this short post, I would like to discuss a special case of the construction introduced in the first part of the series, that is compute the set , where is the antisymmetric subspace of the tensor product. This example … Continue reading

A couple of days ago, I remembered the following fun fact from my highschool days in Romania: First, note that I am using the European notation for periodic decimal expansions (or repeating decimals). What you get is a periodic expansion, … Continue reading
