  Photon-number-revolving (PNR) detection allows the direct measurement of the
Wigner quasiprobability distribution of an optical mode without the need for
numerically processing an inverse Radon transform [K. Banaszek and K.
W\'odkiewicz, Phys. Rev. Lett. 76, 4344 (1996)]. In this work, we reproduced
the seminal experiment of Banaszek et al. [Phys. Rev. A 60, 674 (1999)] of
quantum tomography of a pure coherent state, and of a statistical mixture
thereof, and extended it to the more general case of photon fluxes with much
more than one photon per detection time. This was made possible by the use of a
superconducting transition-edge sensor to perform PNR detection from 0 to 5
photons at 1064 nm, at about 70% system efficiency and with no dead time. We
detail signal acquisition and detection efficiency and discuss prospects for
applying such quantum tomography to non-Gaussian states.
