Abstract
In order to improve the anti-noise performance of quantum teleportation, this
paper proposes a novel dynamic quantum anti-noise scheme based on the quantum
teleportation which transmits single qubit state using Bell state. Considering that quantum
noise only acts on the transmitted qubit, i.e., the entangled state that Alice and Bob share
in advance is affected by the noise, thus affecting the final transmission result. In this
paper, a method for dynamically adjusting the shared entangled state according to the
noise environment is proposed. By calculating the maximum fidelity of the output state to
determine the shared entangled state, which makes the quantum teleportation be affected
by the noise as little as possible. This paper calculates the fidelity of teleportation under
four kinds of channel noise (amplitude damping, phase damping, bit flip and depolarizing
noise). The results show that the scheme has a suppression effect on phase damping, bit
flip and depolarizing noise under certain conditions. When the noise intensity is larger,
the optimized efficiency is better.
