  • In Ref. [1], Zheng proposed a scheme for implementing a conditional phase shift via adiabatic passages. The author claims that the gate is “neither of dynamical nor geometric origin” on the grounds that the Hamiltonian does not follow a cyclic change. He further argues that “in comparison with the adiabatic geometric gates, the nontrivial cyclic loop is unnecessary, and thus the errors in obtaining the required solid angle are avoided, which makes this new kind of phase gates superior to the… CONTINUE READING
