Query: Experimental verification of fluctuation relations with a quantum
  computer   Inspired by the idea that quantum computers can be useful in advancing basic
science, we use a quantum processor to experimentally validate a number of
theoretical results in non-equilibrium quantum thermodynamics, that were not
(or were very little) corroborated so far. In order to do so, we first put
forward a novel method to implement the so called two point measurement scheme,
which is at the basis of the study of non-equilibrium energetic exchanges in
quantum systems. Like the well-established interferometric method, our method
uses an ancillary system, but at variance with it, it provides direct access to
the energy exchange statistics, rather than its Fourier transform, thus being
extremely more effective. We first experimentally validate our ancilla-assisted
two point measurement scheme, and then apply it to i) experimentally verify
that fluctuation theorems are robust against projective measurements, a
theoretical prediction which was not validated so far, ii) experimentally
verify the so called heat engine fluctuation relation, by implementing a SWAP
quantum heat engine. iii) experimentally verify that the heat engine
fluctuation relation continues to hold in presence of intermediate
measurements, by implementing the design at the basis of the so called
quantum-measurement-cooling concept. For both engines, we report the measured
average heat and work exchanged and single out their operation mode. Our
experiments constitute the experimental basis for the understanding of the
non-equilibrium energetics of quantum computation and for the implementation of
energy management devices on quantum processors.
