- Abstract
- 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.
