Abstract

We study the entanglement protection between two identical qubits interacting with independent zero-temperature reservoir beyond the Born-Markoivan approximation. The principle is based on an analog of a zero-ground quantum screening method in an electronic circuit, it employs an auxiliary casing system to erase the excited state to the ground state frequently to inhibit the decoherence. We find that the auxiliary casing system plays a crucial role and the number of screening events is proportional to the entanglement protection, the physical mechanism is also given in the context.
