classical bits which may not be desired and has to be compensated by loosing precision in using a shorter set of classical bits. A single quantum state, however, can take all that information in a single shot. Hence, sending known quantum states, either considered as state transfer or remote state preparation, has its own merit while has hardly been studied for spin spin chain communication [@bayat-densecoding].

Quantum measurement is one of the mysteries of physics which has been hardly understood since the birth of quantum mechanics. According to quantum theory, measuring any observable results in a *random* output which is one of the eigenvalues of a Hermitian operator that is associated to that particular observable. The probability of such an outcome is determined by the overlap of the initial wave function and the corresponding eigenvector of the observable operator. In fact, after the measurement the wave function of the system goes under an abrupt change and collapses to that particular eigenstate of the observable operator. So far, the quantum measurement has been exploited for quantum communication via teleportation [@Bennet-teleportation] and measurement-based quantum computation [@Briegel-MBQC]. In conventional spin chain quantum communications, however, the random nature of measurement has been an obstacle
