  The topological degeneracy of ground states in transverse field Ising chain
cannot be removed by local perturbation and allows it to be a promising
candidate for topological computation. We study the dynamic processes of
crystallization and dissolution for the gapped ground states in an Ising chain.
For this purpose, the real-space renormalization method is employed to build an
effective Hamiltonian that captures the low-energy physics of a given system.
We show that the ground state and the first-excited state of an $ \left(
N+1\right) $-site chain can be generated from that of the $N$-site one by
adding a spin adiabatically and vice versa. Numerical simulation shows that the
robust quasidegenerate ground states of finite-size chain can be prepared with
high fidelity from a set of noninteracting spins by a quasiadiabatic process.
As an application, we propose a scheme for entanglement transfer between a pair
of spins and two separable Ising chains as macroscopic topological qubits.
