We present a systematic scheme for deterministic teleportation in a quantum switch network based on probabilistic communication channels. In this scheme, the burden of terminal agents originally caused by the introduction of auxiliary qubits and the operations of high dimensional unitary gates could be released. In such a way, our scheme will bring great convenience to realize deterministic teleportation in quantum probabilistic network for the present purpose.

In physics experiments, it is very difficult to realize directly using high-dimensional unitary operations. In order to decrease or avoid the shortage during the teleportation process based on probabilistic channel, we propose a new scheme to reconstruct a deterministic teleportation eight-qubit channel using Bell-state measurements based on the probabilistic channel, which replaces high-dimensional unitary operations. In our scheme, a new quantum channel without alterable parameters replaces the general quantum channel with parameters as probabilistic teleportation. It shows that if we choose an eight-qubit probabilistic channel to construct deterministic channel, the relevant parameters of the eight-qubit probabilistic channel can be avoided. Thus, in quantum teleportation process, quantum channel can be chosen as a deterministic channel. This shows that our scheme makes real experiments more suitable.
