Trapped-Ion Quantum Simulation of Open Quantum Systems
Abstract
Dealing with large quantum mechanical systems is known to be computationally difficult. Since the size of the Hilbert space of a qua,ntum many-body system grows exponentially with the number of particles, large-scale simulations of quantum systems become classicall,y intractable. One promising approach to address these challenges is using quantum processors for directly simulating many-body syst,ems and other natural phenomena. So far many of these studies have focused on closed quantum systems that are isolated from the envi,ronment. However, all experimental quantum systems can be considered isolated only up to a certain extent as the coupling between th,e system and the environment cannot be completely eliminated. In this context, this project aims to investigate the competition and, interplay amongcarefully engineered dissipative processes and coherent drive in a trapped-ion quantum system, one of the most coher,ent quantum simulation platforms. This proposal will focus on introducing tailored and controlled dissipation on the motional degree,s of freedom ina scalable way. The control of this effective reservoir opens completely new avenues to quantum simulations, for exam,ple, unlockingthe access of direct simulation of chemical reactions and biological processes. By using fast and high-efficiency side,band cooling to implement reservoir engineering and single ion addressing to tailor spin-spin couplings, we will study in a controll,ed setting both quantum and classical electron dynamics regimes, depending on the experimental parameters. Using a tunable and well-,controlled quantum simulator will allow the study of regimes inaccessible by current numerical methods, potentially shedding light o,n the electron dynamics in complex molecules. If successful, this effort will be a steppingstone in our understanding of open quantu,m systems andwill ultimately help guide the design of photosynthetic materials for highly efficient and cost-effective light-harvest,ing devices.These devices could be deployed in the field as an effective source of energy for all outdoor military operations and co,uld providea valuable energy source for navigation in the open sea.
