Semiclassical asymptotics of multiphotonic scattering probabilities with partial indistinguishability
Alonso Botero, Hubert de Guise, Orlando Melo-Vargas
We propose a framework for computing multiphotonic scattering probabilities in a lossless multiport interferometer for arbitrary photon numbers and degrees of indistinguishability.…

Mixed symmetries of S_n: immanants in the sampling of U(d) submatrices
Jacob Daigle, Hubert de Guise, Trevor Welsh
We provide results on the mean and higher moments of immanants of submatrices of ensembles of Haar-distributed unitary matrices, mostly without proofs. This paper is based on a tal…

Qudit non-Clifford interleaved benchmarking
David Amaro-Alcalá, Barry C. Sanders, Hubert de Guise
We introduce a scheme to characterise a qudit T gate that has different noise than a set of Clifford gates. We developed our scheme through representation theory and ring theory to…
