    "abstract": "Displaced Fock states of the electromagnetic field have been synthesized by\noverlapping the pulsed optical single-photon Fock state |1\u003e with coherent\nstates on a high-reflection beamsplitter and completely characterized by means\nof quantum homodyne tomography. The reconstruction reveals highly non-classical\nproperties of displaced Fock states, such as negativity of the Wigner function\nand photon number oscillations. This is the first time complete tomographic\nreconstruction has been performed on a highly non-classical optical state.",
