    "abstract": "Inconclusive photon subtraction (IPS) is a conditional measurement scheme to\nforce nonlinear evolution of a given state. In IPS the input state is mixed\nwith the vacuum in a beam splitter and then the reflected beam is revealed by\nON/OFF photodetection. When the detector clicks we have the (inconclusive)\nphoton subtracted state. We show that IPS on both channels of an entangled\ntwin-beam of radiation improves the fidelity of coherent state teleportation if\nthe energy of the incoming twin-beam is below a certain threshold, which\ndepends on the beam splitter transmissivity and the quantum efficiency of\nphotodetectors. We show that the energy threshold diverges when the\ntransmissivity and the efficiency approach unit and compare our results with\nthat of previous works on {\\em conclusive} photon subtraction.",
