Using exchange attenuation to control non-disentanglement quantum information transport in phase damping channel

  It is effective to constitute a hybrid qubit system by taking advantages of different types of qubits to overcome the effects of decoherence and achieve quantum information transport.We find that energy relaxation exists in the process of information exchange bewteen the hybrid qubits.Combining this kind of energy relaxation with the decoherence effects from external environment,quantum information transport of non-disentangled effect can be achieved in phase damping channel if the exchange decay rate and decoherence time satisfy certain constraint relations.
