1210.8238 (Jun Feng et al.)

Notes on teleportation in an expanding space    [PDF]

Jun Feng, Wen-Li Yang, Yao-Zhong Zhang, Heng Fan
We investigate the quantum teleportation between a conformal detector Alice and an inertial detector Bob in de Sitter space. We show that the fidelity of the teleportation is degraded for Bob due to the Gibbons-Hawking effect associated with his cosmological event horizon. With a cutoff at Planck-scale, comparing with the standard Bunch-Davies choice, we also show that the possible Planckian physics cause extra modifications to the fidelity of the teleportation process.
