The Quantum Teleportation Fidelity of the Squeezed Vacuum State

摘要

We use two-mode squeezed vacuum state as a quantum channel to teleportate the quantum squeezed vacuum state and analyze the fidelity of the teleportation by the Wigner function. The result shows that the squeeze factor of the quantum squeezed vacuum state is smaller, the quantum features of the teleportation state is more easily preserved.
