通过电脉冲实验证明了半导体双量子点中电荷量子位的相干时间演化。量子位状态是通过控制系统能量的矩形或定制电压波形来操纵的。只需在短时间内改变电压即可依次执行初始化、旋转门、相移门和测量过程。 (C) 2003 Elsevier B.V. 保留所有权利。
Coherent time evolution of a charge qubit in a semiconductor double quantum dot is demonstrated by means of electrical pulse experiments. The qubit state is manipulated with a rectangular or tailored voltage waveform that controls the energy of the system. The initialization, rotation gate, phase-shift gate, and measurement process are sequencially performed just by changing the voltage in a short time. (C) 2003 Elsevier B.V. All rights reserved.
