| Abstract: | Implements for geometric quantum gates are analyzed in the electric circuit. We find that, by operating the difference of
geometric phase between eigenstates of Hamiltonian for single-particle system and two-particle system respectively, one may
perfectly preserve the messages for single-particle gate as well as entangling geometric two-particle gate. |
