▎ 摘  要

We used a graphene C-12 matrix doped with C-13 atoms in a squared and center-triangular configuration, where only the interaction C-13-C-13 with their magnetic moments are considered. This is done in the presence of a constant magnetic field parallel to the layers and a transverse rf-magnetic field in order to simulate the NOT gate (single layer), controlled-not quantum gate (two layers), and controlled-controlled-not quantum gate (three layers). However, as it would be explained in more detail throughout this article, a single qubit rotation defined by a single graphene layer was not possible to construct. We found that frequencies needed to perform this transitions do not depend on the number of C-13 atoms on each layer, which means that we can make transitions between two distant states with big separation of energy (m and n states) with lower frequency pulses (w << Delta(s,t)(Ep,Eq)).
