About the possibility for using graphene layers 12 C–13 C for quantum computation
We used a graphene 12 C matrix doped with 13 C atoms in a squared and center-triangular configuration, where only the interaction 13 C – 13 C 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 fiel...

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

atoms on each layer, which means that we can make transitions between two distant states with big separation of energy levels (
m
and
n
states) with lower frequency pulses
