- Abstract: In this article, we investigate the problem of state reconstruction of
four-level quantum systems. A realistic scenario is considered with measurement
results distorted by random unitary operators. Two frames which define
injective measurements are applied and compared. By introducing arbitrary
rotations, we can test the performance of the framework versus the amount of
experimental noise. The results of numerical simulations are depicted on graphs
and discussed. In particular, a class of entangled states is reconstructed. The
concurrence is used as a figure of merit in order to quantify how well
entanglement is preserved through noisy measurements.

In this work, we investigate the characterization of updated states of multi-partite entangled qubit states with non-destructive weak measurements.
As is well-known, the updated state at intermediate times is frame-dependent, and outcome randomness intrinsic to projective measurements prevents any information to be acquired on the updated state.

Machine learning inspired variational methods provide a promising route towards scalable state characterization for quantum simulators.
We benchmark and compare several such approaches by applying them to measured data from an experiment producing two-qubit entangled states.
We find that in the presence of experimental imperfections and noise, confining the variational manifold to physical states greatly improves the quality of the reconstructed states.
