Abstract
In this paper, we propose a scheme of controlled remote quantum information concentration via non-maximally entangled GHZ-type states as quantum channel, which is the reverse process of the 1→3 optimal asymmetric economical phase-covariant telecloning. The necessary measurements and operations are given in detail.
