Abstract
We propose a possible way, theoretically, to manipulate a Schrödinger cat state of two degenerate ferromagnetic [FM] ground states of the transverse Ising model [TIM] using macroscopic quantum tunneling (MQT) effect. The MQT process is calculated based on a high-order degenerate perturbative method and can be understood in the language of individual virtual fermions hopping along the spin chain. We present an analytical description of the tunneling process, and discuss experimental feasibility for generating the Cat state in the linear ion trap.
