Query: Benchmarking maximum-likelihood state estimation with an entangled
  two-cavity state   The efficient quantum state reconstruction algorithm described in [P. Six et
al., Phys. Rev. A 93, 012109 (2016)] is experimentally implemented on the
non-local state of two microwave cavities entangled by a circular Rydberg atom.
We use information provided by long sequences of measurements performed by
resonant and dispersive probe atoms over time scales involving the system
decoherence. Moreover, we benefit from the consolidation, in the same
reconstruction, of different measurement protocols providing complementary
information. Finally, we obtain realistic error bars for the matrix elements of
the reconstructed density operator. These results demonstrate the pertinence
and precision of the method, directly applicable to any complex quantum system.
