论文摘要
我们建议使用被困在石墨烯纳米内表面的电子的量子状态，以将其作为一种新型的物理量子位实现，可用于编码量子信息。然后可以使用外部磁场和电场执行量子信息处理的基本任务，例如量子量初始化和任意单量子门的实现。我们还分析了设备再次系统误差的鲁棒性，可以通过适当的外部控制场选择来抑制这些误差。这些发现为开发开辟了新的前景，这是量子计算的替代平台，其可扩展性尚待确定。
We propose to use the quantum states of an electron trapped on the inner surface of a graphene nanotorus to realize as a new kind of physical quantum bit, which can be used to encode quantum information. Fundamental tasks for quantum information processing, such as the qubit initialization and the implementation of arbitrary single qubit gates, can then be performed using external magnetic and electric fields. We also analyze the robustness of the device again systematic errors, which can be suppressed by a suitable choice of the external control fields. These findings open new prospects for the development an alternative platform for quantum computing, the scalability of which remains to be determined.
