We study the remote creation of the polarization and intensity of thefirst-order coherence (or coherence intensity) in long spin-1/2 chains with onequbit sender and receiver. Therewith we use a physically motivated initialcondition with the pure state of the sender and the thermodynamical equilibriumstate of the other nodes. The main part of the creatable region is a one-to-onemap of the initial-state (control) parameters, except the small subregion twicecovered by the control parameters, which appears owing to the chosen initialstate. The polarization and coherence intensity behave differently in the statecreation process. In particular, the coherence intensity can not reach anysignificant value unless the polarization is large in long chains (unlike theshort ones), but the opposite is not true. The coherence intensity vanisheswith an increase in the chain length, while the polarization (by absolutevalue) is not sensitive to this parameter. We represent several characteristicsof the creatable polarization and coherence intensity and describe theirrelation to the parameters of the initial state. The link to theeigenvalue-eigenvector parametrization of the receiver's state-space is given.
