    "abstract": "We present two experimental schemes to perform continuous variable (2,3)\nthreshold quantum secret sharing on the quadratures amplitudes of bright light\nbeams. Both schemes require a pair of entangled light beams. The first scheme\nutilizes two phase sensitive optical amplifiers, whilst the second uses an\nelectro-optic feedforward loop for the reconstruction of the secret. We examine\nthe efficacy of quantum secret sharing in terms of fidelity, as well as the\nsignal transfer coefficients and the conditional variances of the reconstructed\noutput state. We show that both schemes in the ideal case yield perfect secret\nreconstruction.",
