基于类似晶体管的硅MOS纳米器件的量子比特在量子计算中很有前途。在这项工作中,我们展示了一种双量子点自旋量子比特,它是全电子控制的,不需要任何外部组件,如微磁铁,这可能会使集成复杂化。量子比特的普遍控制是通过自旋-轨道类相互作用和交换相互作用实现的。使用单次读出,我们展示了直流和交流控制技术。所使用的制造技术与CMOS完全兼容。
Qubits based on transistor-like Si MOS nanodevices are promising for quantum computing. In this work, we demonstrate a double quantum dot spin qubit that is all-electrically controlled without the need for any external components, like micromagnets, that could complicate integration. Universal control of the qubit is achieved through spin-orbit-like and exchange interactions. Using single shot readout, we show both DC-and AC-control techniques. The fabrication technology used is completely compatible with CMOS.
