In this paper, we investigate generalized remote information concentration as the reverse process of ancilla-free phase-covariant telecloning (AFPCT) which is different from the reverse process of optimal universal telecloning. It is shown that the quantum information via $$1\rightarrow 2$$ 1 → 2 AEPCT procedure can be remotely concentrated back to a single qubit with a certain probability by utilizing (non-)maximally entangled $$W$$ W states as quantum channels. Our protocols are the generalization of Wang’s scheme (Open J Microphys 3:18–21. doi: 10.4236/ojm.2013.31004 , 2013). And von Neumann measure and positive operator-valued measurement are performed in the maximal and non-maximal cases respectively. Relatively the former, the dimension of measurement space in the latter is greatly reduced. It makes the physical realization easier and suitable.
