Magdalena Stobińska, Gerard J. Milburn, Leszek Stobiński

摘要:

我们研究实验证明单电子${}^{12}$ C CNT QD具有显着的自旋轨道相互作用作为一个可扩展的量子计算机候选人。电子自旋和轨道角动量都可以作为用于量子处理的逻辑量子比特。我们引入宏观量子存储系统的形式注入磁性或自旋携带原子系综到纳米管。碳纳米管在有限温度下具有稳定的原子陷阱,在外加磁场中具有一维核自旋晶格。电子通过磁相互作用或超精细相互作用与原子系综耦合。该系统可实现简单的电子和核自旋读出。

英文摘要:

We study experimentally demonstrated single-electron ${}^{12}$C CNT QD with significant spin-orbit interaction as a scalable quantum computer candidate. Both electron spin and orbital angular momentum can serve as a logical qubit for quantum processing. We introduce macroscopic quantum memory for the system in a form of injected either magnetic or spin carrying atomic ensemble into the nanotube. CNT provides with a stable atomic trap in finite temperature and with one-dimensional nuclear spin lattice in an external magnetic field. The electron is coupled to the atomic ensemble through either magnetic or hyperfine interaction. Easy electron and nuclear spin read-out procedure for this system is possible.
