Linear cross-entropy certification of quantum computational advantage in Gaussian Boson Sampling
Javier MartÃnez-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…

Randomised benchmarking for universal qudit gates
David Amaro-Alcalá, Barry C. Sanders, Hubert de Guise
We aim to establish a scalable scheme for characterising diagonal non-Clifford gates for single- and multi-qudit systems; \(d\) is a prime-power integer. By employing cyclic operat…

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…
