Abstract
An entanglement control strategy is presented for two-qubit quantum systems against Markovian noises. This proposal is realized by a tunable coupling between qubits which is induced by varying the parameters of an intermediate squeezed field. Its applications to the independent and collective amplitude damping decoherence channels and their mixture show that entanglement can be efficiently enhanced.
