Three-dimensional simulation of quantum cellular automata and the zero-dimensional approximation
Hua Wu, Donald W. L. Sprung · Journal of Applied Physics · 1998
We present a three-dimensional simulation of the quantum cellular automaton introduced by Lent et al. [P. D. Tougaw and C. S. Lent, J. Appl. Phys. 75, 1818 (1994)]. The Hamiltonian for their Hubbard model is derived as a zero-dimensional approximation to the Hamiltonian in our simulation. This provides a link between device properties and the phenomenological parameters such as tunneling coefficients.
