$C^{12}-C^{13}$ Quantum computer with longitudinal rf-magnetic field

Abstract

It is shown that in the diamond $C^{12}$ structure with a linear chain of $C^{13}$ atoms which is inside a transverse static field, having a gradient along the linear chain and an rf-magnetic field in a plane with a component in the direction of the static field, one qubit rotation, the Controlled-Not (CNOT), the Controlled-Controlled-NoT (CCNOT) quantum gates, and teleportation algorithm.
