  We present a scheme that utilizes an ion confined within a bi-dimensional
trap to simulate a quantum Otto heat engine whose working substance is a
two-level system. In this scheme, the electronic component of the ion (the
two-level system) can interact with effective heat reservoirs of different
types. We specifically focus on effective thermal reservoirs (those with
positive temperatures), effective heat reservoirs with apparent negative
temperatures, and effective squeezed thermal reservoirs. We show how to
generate these effective reservoirs and provide numerical results to illustrate
the applicability of the presented scheme. Finally, considering the same types
of effective heat reservoirs, we briefly discuss the simulation of a quantum
Otto heat engine where a quantum harmonic oscillator serves as the working
substance.
