Realistic continuous-variable quantum teleportation using a displaced Fock state channel

We investigate ideal and non-ideal continuous-variable quantum teleportation protocols realized by using an entangled displaced Fock state resource. The characteristic function formulation is applied to measure the relative performance of for teleporting squeezed coherent states. It found that such single-mode input fields, average fidelity remains at classical threshold, suggesting states are not advantageous teleportation. also discuss major decoherence effects, caused inaccuracy in Bell measurements photon losses propagation optical fields via fibre channels. changes described adjusting gain factor ($g$), reflectivity ($R$), mode damping ($\tau$), number thermal photons ($n_\mathrm{th}$). possibility successful can be optimized fixing these realistic parameters.
