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. © 2011 American Physical Society. ; J.

We design a quantum simulator for the Majorana equation, a non-Hamiltonian relativistic wave equation that might describe neutrinos and other exotic particles beyond the standard model. Driven by the need of the simulation, we devise a general method for implementing a number of mathematical operations that are unphysical, including charge conjugation, complex conjugation, and time reversal. Furthermore, we describe how to realize the general method in a system of trapped ions. The work opens a new front in quantum simulations. ; The authors acknowledge funding from Basque Government Grants No. BFI08.211, IT559-10, and No. IT472-10; Spanish MICINN FIS2008-05705, FIS2009- 10061, and FIS2009-12773-C02-01; QUITEMAD; the EC Marie-Curie program; and the CCQED and SOLID European projects. ; Peer Reviewed
