Analog quantum chemistry simulation with ultra-cold atoms

2019 edition

Javier Arg├╝ello-Luengo

Computing the electronic structure of molecules is a central challenge in industry, catalysis research or drug design. Despite the enormous success of approximate methods, facing this problem exactly with conventional computers is still a tremendous challenge. This has triggered theoretical and experimental efforts to use quantum computers to solve chemistry problems [1]. An appealing strategy is analog quantum simulation, which does not require a fully operative computer. In the same way that architects can identify optimal surfaces by studying soap films, this approach uses a highly controllable device ÔÇöthe simulatorÔÇö┬á to mimic the system of interest and gain information about the desired solution. In the quantum world, this strategy has already been successfully applied to condensed matter and high-energy physics problems. In this talk we will introduce our recent proposal about how it is possible to also simulate quantum chemistry problems using ultra-cold atoms as a simulator [2].
