Generating series and matrix models for meandric systems with one shallow side
Motohisa Fukuda, Ion Nechita
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 introduced a…
Generating random quantum channels
Ryszard Kukulski, Ion Nechita, Łukasz Pawela +2
Several techniques of generating random quantum channels, which act on the set of -dimensional quantum states, are investigated. We present three approaches to the problem of sa…
Multipartite entanglement detection via projective tensor norms
Maria Anastasia Jivulescu, Cécilia Lancien, Ion Nechita
We introduce and study a class of entanglement criteria based on the idea of applying local contractions to an input multipartite state, and then computing the projective tensor no…
Diagonal unitary and orthogonal symmetries in quantum theory
Satvik Singh, Ion Nechita
We analyze bipartite matrices and linear maps between matrix algebras, which are respectively, invariant and covariant, under the diagonal unitary and orthogonal groups' actions. B…
A graphical calculus for integration over random diagonal unitary matrices
Ion Nechita, Satvik Singh
We provide a graphical calculus for computing averages of tensor network diagrams with respect to the distribution of random vectors containing independent uniform complex phases.…
SudoQ -- a quantum variant of the popular game
Ion Nechita, Jordi Pillet
We introduce SudoQ, a quantum version of the classical game Sudoku. Allowing the entries of the grid to be (non-commutative) projections instead of integers, the solution set of Su…
