We used a graphene 12 C matrix doped with 13 C atoms in a squared and center-triangular configuration, where only the interaction 13 C13 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 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 13 C 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 wΔEp,Eqs,t .

关于使用石墨烯层 12 C–13 C 进行量子计算的可能性

我们使用了石墨烯12 C矩阵掺杂13 C正方形和中心三角形构型的原子,其中只有相互作用13 C13 C考虑了它们的磁矩。这是在存在平行于层的恒定磁场和横向射频磁场的情况下完成的,以模拟非门(单层)、受控非量子门(两层)和受控-受控-非量子门(三层)。然而,正如本文将更详细地解释的那样,不可能构建由单个石墨烯层定义的单个量子位旋转。我们发现执行此转换所需的频率不取决于13的数量 C每层上的原子,这意味着我们可以在两个具有很大能级分离的远距离状态之间进行转换(n状态)与较低频率的脉冲 wp,q, .
