扩大量子位是实现有用的量子计算系统的必要步骤。在这里，我们展示了在四量子点的每个点中使用微磁体方法对四个单独电子自旋的相干操纵，四量子点是多量子点中用于单自旋控制的最大数量的点。我们通过电子自旋共振观察每个点的拉比振荡，评估四个点的自旋电耦合，最后讨论在包含更多量子点的多量子点系统中独立解决单自旋的实用方法。由 AIP 出版社出版。
Scaling up qubits is a necessary step to realize useful systems of quantum computation. Here, we demonstrate coherent manipulations of four individual electron spins using a micro-magnet method in each dot of a quadruple quantum dot-the largest number of dots used for the single spin control in multiple quantum dots. We observe Rabi oscillations for each dot through electron spin resonance, evaluate the spin-electric coupling of the four dots, and finally discuss practical approaches to independently address single spins in multiple quantum dot systems containing even more quantum dots.
