Measuring the discrete Wigner function

As a last topic in this chapter, we review the work of Miquel et al. [29] who implemented a quantum circuit to measure the discrete Wigner function of a two-qubit system through NMR. In Chapter 3 it was made a brief introduction to Wigner functions and the quantum processing of information in phase space.
