We propose the quantum simulation of fermion and antifermion field modes interacting via a bosonic field mode, and present a possible implementation with two trapped ions. This quantum platform allows for the scalable add up of bosonic and fermionic modes, and represents an avenue towards quantum simulations of quantum field theories in perturbative and nonperturbative regimes.

Experimental quantum simulation of fermion-antifermion scattering via boson exchange in a trapped ion

The authors use a multilevel trapped ion to simulate the processes of self-interaction and particle-antiparticle creation/annihilation, using a simplified model of fermion scattering in both perturbative and non-perturbative quantum electrodynamics.

Quantum Simulation of a Lattice Schwinger Model in a Chain of Trapped Ions

Gauge theories such as quantum electrodynamics, in principle, give us a precise understanding of the interactions between subatomic particles, but often the calculations involved are beyond current

Fermion-fermion scattering in quantum field theory with superconducting circuits.

An analog-digital quantum simulation of fermion-fermion scattering mediated by a continuum of bosonic modes within a circuit quantum electrodynamics scenario is proposed and the complexity-simulating-complexity concept should become a leading paradigm in any effort towards scalable quantum simulations.

This work presents a method of simulating the Dirac equation in 3+1 dimensions for a free spin-1/2 particle in a single trapped ion, and studies relevant quantum-relativistic effects, like the Zitterbewegung and Klein's paradox, the transition from massless to massive fermions, and the relativistic and nonrel ativistic limits, via the tuning of controllable experimental parameters.
