Abstract
Homodyne tomography and heterodyne detection are principal measurement schemes in continuous-variable quantum information and provide different accuracies in determining the quantum state of a system. The former allows for a tomographic reconstruction of the Wigner function of the state, whereas the latter directly samples its Husimi Q-function. We experimentally demonstrate that contrary to a common belief, heterodyne detection outperforms homodyne tomography for almost all Gaussian states.
