Teleportation in the background of Schwarzschild space–time

Quantum teleportation is investigated between Alice who is far from the horizon and Bob locates near the event horizon of a Schwarzschild black hole. The results show that the fidelity of the teleportation is reduced in this curved space–time. However, high fidelity can still be reached outside a ma...

Description
Summary:Quantum teleportation is investigated between Alice who is far from the horizon and Bob locates near the event horizon of a Schwarzschild black hole. The results show that the fidelity of the teleportation is reduced in this curved space–time. However, high fidelity can still be reached outside a massive black hole.
