  The primary obstacle in the field of quantum thermodynamics revolves around
the development and practical implementation of quantum heat engines operating
at the nanoscale. One of the key challenges associated with quantum working
bodies is the occurrence of "quantum friction," which refers to irreversible
wasted work resulting from quantum inter-level transitions. Consequently, the
construction of a reversible quantum cycle necessitates the utilization of
adiabatic shortcuts. However, the experimental realization of such shortcuts
for realistic quantum substances is exceedingly complex and often unattainable.
In this study, we propose a quantum heat engine that capitalizes on the
plasmonic skyrmion lattice. Through rigorous analysis, we demonstrate that the
quantum skyrmion substance, owing to its topological protection, exhibits zero
irreversible work. Consequently, our engine operates without the need for
adiabatic shortcuts. We checked by numerical calculations and observed that
when the system is in the quantum skyrmion phase, the propagated states differ
from the initial states only by the geometricl and dynamical phases. The
adiabacit evoluation leads to the zero transition matrix elements and zero
irreversible work. By employing plasmonic mods and an electric field, we drive
the quantum cycle. The fundamental building blocks for constructing the quantum
working body are individual skyrmions within the plasmonic lattice. As a
result, one can precisely control the output power of the engine and the
thermodynamic work accomplished by manipulating the number of quantum skyrmions
present.
