The block-ZXZ synthesis of an arbitrary quantum circuit

Alexis De Vos, Stijn De Baerdemacker

Given an arbitrary unitary matrix , a powerful matrix decomposition can be applied, leading to four different syntheses of a -qubit quantum circuit performin…

Maximum Probability Domains for Hubbard Models

Guillaume Acke, Stijn De Baerdemacker, Pieter W. Claeys +4

The theory of Maximum Probability Domains (MPDs) is formulated for the Hubbard model in terms of projection operators and generating functions for both exact eigenstates as well as…

The Birkhoff theorem for unitary matrices of prime dimension

Alexis De Vos, Stijn De Baerdemacker

The Birkhoff's theorem states that any doubly stochastic matrix lies inside a convex polytope with the permutation matrices at the corners. It can be proven that a similar theorem…

Eigenvalue-based determinants for scalar products and form factors in Richardson-Gaudin integrable models coupled to a bosonic mode

Pieter W. Claeys, Stijn De Baerdemacker, Mario Van Raemdonck +1

Starting from integrable (quasi-)spin Richardson-Gaudin XXZ models we derive several properties of integrable spin models coupled to a bosonic mode. We focus on the Dicke-J…

An eigenvalue-based method and determinant representations for general integrable XXZ Richardson-Gaudin models

Pieter W. Claeys, Stijn De Baerdemacker, Mario Van Raemdonck +1

We propose an extension of the numerical approach for integrable Richardson-Gaudin models based on a new set of eigenvalue-based variables. Starting solely from the Gaudin algebra,…
