Fast quantum data transmission faces several shortcomings such as the indistinguishability of some partly overlapping signals, the channel noises, and so on. Based on the encoded quantum data transmission protocol, an unconventional scheme is presented to overcome the indistinguishability problem of the encoded qubits effectively, so that the upper bound for qubit transmission rate can be considerably raised compared with the un-encoded cases. It can be regarded as a combination of an entanglement swapping technique and a quantum error-correcting scheme, which also provides us a new way of thinking for improving other technologies such as quantum communication, quantum storage technology etc. Besides, from the quantum error correction's point of view, our technique can also be regarded as a method to deal with some families of nonlocal errors, which may facilitate the research in the relevant field.
