Meet the FoQaCiA partners: University of Granada
The University of Granada FoQaCiA node is coordinated by PI Jara Juana Bermejo-Vega, with contributions to all scientific workpackages of the project, notably to WP2 on the complexity of classical simulation of quantum computation.
Some of the recent output of the Granada node includes an open software package for improved simulation of certain non-Clifford unitary gates, and a paper on the efficient experimental verification of graph states, useful in measurement-based quantum computation. You can watch a talk Jara Juana gave on this topic in this year’s FoQaCiA workshop, available here, with the following summary:

Title: Reliable quantum computational advantages from quantum simulation
Abstract: Demonstrating quantum advantages in near term quantum devices is a notoriously difficult task. Ongoing efforts try to overcome different limitations of quantum devices without fault-tolerance, such as their limited system size or obstacles towards verification of the outcome of the computation. Proposals that exhibit more reliable quantum advantages for classically hard-to-simulate verifiable problems lack, at the same time, practical applicability. In this talk we will review different approaches to demonstrate quantum advantages inspired from many-body quantum physics. The first of them use entangled quantum resources such as cluster states, which are useful to demonstrate verifiable quantum advantages based on sampling problems (Theory proposal Phys. Rev. X 8, 021010, 2018 and recent experimental demonstration arXiv preprint arXiv:2307.14424). The second probe measurement of many-body quantities such as dynamical structure factors in quantum simulation setups (Proceedings of the National Academy of Sciences 117 (42), 26123-26134).
About FoQaCiA
The FoQaCiA project aims to advance the understanding of the fundamental principles and methodologies that underpin the development of quantum algorithms. This includes exploring new algorithmic frameworks, optimizing existing quantum processes, and identifying innovative approaches to leverage quantum computing's unique capabilities. The project involves 11 partners from Canada and the EU and is funded by NSERC, the European Commission, and UKRI. The project started in October 2022 and has already resulted in 7 open software packages and 57 preprints and papers, among other outputs.
