This talk will cover recent advances in the field of Quantum Thermodynamics, an emerging field that aims to uncover the thermodynamic laws at the nanoscale . I will begin with explaining a (classical) nanoscale thermodynamic experiment with optically trapped nanospheres that undergo Brownian motion in air . These spheres experience a non-equilibrium situation due to heating from the trapping laser. By using a suitable two-bath model to analyse the data, one can infer the surface temperature of the trapped spheres and also observe temperature gradients across the nanospheres. I will then move on to theoretical results concerning thermodynamic work in the quantum regime, i.e. can a different amount of work be extracted from a quantum system than from a classical system? To solve this we set up a quantum thermodynamic process that removes quantum information in analogy to Landauer’s erasure of classical information. The thermodynamic analysis of such a process uncovers that work can be extracted from quantum coherences in addition to the work that can be extracted from classical non-equilibrium states . Finally, I will report on a thermodynamic uncertainty relation that limits the accuracy of measuring the temperature and energy of a thermal quantum system . Corrections to the standard uncertainty relation arise here because, unlike in standard thermodynamics, a small system’s interaction with its environment is not negligible. The emerging relation unites thermodynamic and quantum uncertainties for the first time.
