Controlled Quantum Teleportation of Superposed Coherent State using GHZ Entangled Coherent State
arXiv:1904.11710
Abstract
Controlled quantum teleportation of superposed coherent states using GHZ entangled 3-mode coherent states is studied. Proposed scheme can be implemented experimentally using linear optical components such as a symmetric lossless beam splitter, two phase-shifters and two photon counters. Fidelity is found close to unity for appreciable mean number of photons in coherent states and is 0.99 for mean photon number equal to two.
A preliminary version was presented at National Laser Symposium-26 held at BARC, Mumbai, in December 2017
