Linear cross-entropy certification of quantum computational advantage in Gaussian Boson Sampling
Javier Martínez-Cifuentes, Hubert de Guise, Nicolás Quesada
Validation of quantum advantage claims in the context of Gaussian Boson Sampling (GBS) currently relies on providing evidence that the experimental samples genuinely follow their c…
Benchmarking of universal qutrit gates
David Amaro-Alcalá, Barry C. Sanders, Hubert de Guise
We introduce a characterisation scheme for a universal qutrit gate set. Motivated by the rising interest in qutrit systems, we apply our criteria to establish that our hyperdihedra…
covariant -parametrized maps
Andrei B. Klimov, Ulrich Seyfarth, Hubert de Guise +1
We propose a practical recipe to compute the -parametrized maps for systems with symmetry using a connection between the and symbols through the action…
Interferometrically estimating a quadratic form for any immanant of a matrix and its permutations
Aeysha Khalique, Hubert de Guise, Barry C. Sanders
We devise a multiphoton interferometry scheme for sampling a quadratic function of a specific immanant for any submatrix of a unitary matrix and its row permutations. The full unit…
Permutational symmetries for coincidence rates in multi-mode multi-photonic interferometry
Abdullah Khalid, Dylan Spivak, Barry C. Sanders +1
We obtain coincidence rates for passive optical interferometry by exploiting the permutational symmetries of partially distinguishable input photons, and our approach elucidates qu…
Simple factorization of unitary transformations
Hubert de Guise, Olivia Di Matteo, Luis L. Sanchez-Soto
We demonstrate a method for general linear optical networks that allows one to factorize any SU() matrix in terms of two SU( blocks coupled by an SU(2) entangling beam spl…
