Quantum: a hybrid algorithm tested on the first commercial platform based on neutral atoms

The research team led by Elisa Ercolessi, of the Department of Physics and Astronomy and local coordinator of the INFN IS “Quantum” (Gruppo IV), has conducted a successful experiment to run a specific quantum optimization algorithm on the first commercial quantum computer, Fresnel, realizsd by the French company PASQAL, whose technology is based on neutral atoms.
The activity is funded by the IFAB project “Quantum Computing Development”, a collaboration among the Department of Physics and Astronomy of the University of Bologna and CINECA, INFN and Leithà-Unipol with the goal of developing new quantum algorithms for industrial applications.

The work, which has been carried out personally by Dr. Simone Tibaldi of the PhD School in Physics, has developed a hybrid optimization algorithm, the so-called Quantum Approximation Optimization Algorithm, that makes use of a combination of quantum and classical resources to solve a typical complex combinatorial problem on a network.
The goal of this work is two-fold: to adapt the algorithm to the experimental characteristics of the quantum platform and benchmark its correct evaluation on the Fresnel machine.

Together with other protocols that are tested worldwide, these results show that the use of a hybrid technology which interfaces classical and quantum computers is in reach and very promising.
