Performance of a two-mode coherent superposed channel in continuous-variable quantum teleportation
A two-mode coherent superposed state generated by operator A = t a b + r a† b† is shown to serve as an entangled channel that achieves CV teleportation fidelities exceeding the classical threshold in selected parameter regimes.
