  We study remote creation of coherence (RCC) for a quantum system, A, with the
help of quantum operations on another system, B, and one-way classical
communication.We show that all the nonincoherent quantum states are useful for
RCC and all the incoherent-quantum states are not. The necessary and sufficient
conditions of RCC for the quantum operations on system B are presented for pure
states. The upper bound of average RCC is derived, giving a relation among the
entanglement (concurrence), the RCC of the given quantum state, and the RCC of
the corresponding maximally entangled state. Moreover, for two-qubit systems we
find a simple factorization law for the average remote-created coherence.
