  We study a quantum-simulation model of a mass enhancement in the fermionic
states, as well as in the bosonic ones, of the supersymmetric quantum
mechanics. The bosonic and fermionic states are graded by a qubit. This model
is so simple that it may be implemented as a quantum simulation of the mass
enhancement taking place when supersymmetry (SUSY) is spontaneously broken.
Here, our quantum simulation means the realization of the target quantum
phenomenon with some quantum-information devices as a physical reality. The
model describes how the quasi-particle consisting of the annihilation and
creation of 1-mode scalar bosons eats the spin effect given by the X-gate, and
how it acquires the mass enhancement in the fermionic states in the spontaneous
SUSY breaking. Our model's interaction does not have any Higgs potential.
Instead, the qubit acts as a substitute for the Higgs potential by the
2-level-system approximation of the double-well potential, and then, the
spontaneous SUSY breaking takes place and the mass is enhanced.
