Resumo
Non-equilibrium thermodynamics and quantum information theory are interrelated research fields
witnessing an increasing theoretical and experimental interest. This is mainly due to the broadness of
these theories, which found applications in many different fields of science, ranging from biology to
the foundations of physics. Here, by employing the orbital angular momentum of light, we propose a
new platform for studying non-equilibrium properties of high dimensional quantum systems.
Specifically, we use Laguerre-Gaussian beams to emulate the energy eigenstates of a two-dimension
quantum harmonic oscillator having angular momentum. These light beams are subjected to a
process realized by a spatial light modulator and the corresponding work distribution is
experimentally reconstructed employing a two-point measurement scheme. The Jarzynski fluctuation
relation is then verified. We also suggest the realization of Maxwell’s demon with this platform.
