Universality cost of non-Gaussian enhancement in continuous-variable quantum teleportation: A fidelity--deviation trade-off
Displacement-covariant deterministic CV teleportation channels have vanishing fidelity deviation for coherent states independent of Gaussianity, while input-selective conditioning creates a trade-off that increases deviation and lowers success probability.
