    In quantum information transfer process, the role of environment leads decoherence and disentanglement. Using the advantages of different types of qubits to constitute a hybrid qubits system is a useful way for overcoming decoherence effects and achieving quantum information transfer. It’s found that through combining the energy loss in the process of information exchange of qubits (exchanging decay between the qubits) and the decoherence effects of the external environment, people can achieve quantum information transfer with no decoherence effects. And the constraint relations matching exchange decay rate and decoherence time in no decoherence effects quantum information transfer were obtained.
