On the asymptotic distribution of block-modified random matrices

O Arizmendi, I Nechita, C Vargas - Journal of Mathematical Physics, 2016 - pubs.aip.org
We study random matrices acting on tensor product spaces which have been transformed by
a linear block operation. Using operator-valued free probability theory, under some mild …

Additive bounds of minimum output entropies for unital channels and an exact qubit formula

M Fukuda, G Gour - IEEE Transactions on Information Theory, 2016 - ieeexplore.ieee.org
We find an upper bound for the minimum output entropy of a unital quantum channel, and
obtain an exact formula for general qubit channels. Our techniques incorporate the Rényi …

On the minimum output entropy of random orthogonal quantum channels

M Fukuda, I Nechita - IEEE Transactions on Information Theory, 2017 - ieeexplore.ieee.org
We consider the sequences of random quantum channels defined by using the Stinespring
formula with Haar-distributed random orthogonal matrices. For any fixed sequence of input …

Generating series and matrix models for meandric systems with one shallow side

M Fukuda, I Nechita - Annales de l'Institut Henri Poincaré D, 2024 - ems.press
In this article, we investigate meandric systems having one shallow side: the arch
configuration on that side has depth at most two. This class of meandric systems was …

On the separability of unitarily invariant random quantum states: The unbalanced regime

I Nechita - Advances in Mathematical Physics, 2018 - Wiley Online Library
We study entanglement‐related properties of random quantum states which are unitarily
invariant, in the sense that their distribution is left unchanged by conjugation with arbitrary …
