Query: Discrete Wigner Function Reconstruction and Compressed Sensing   A new reconstruction method for Wigner function is reported for quantum
tomography based on compressed sensing. By analogy with computed tomography,
Wigner functions for some quantum states can be reconstructed with less
measurements utilizing this compressed sensing based method.
