Transitions between quantum states of a computational basis are driven by the microwave π-pulse. The parameters of the proposed nanodevice have been optimized in order to make the operation cycle of the gate as short as possible. Numerical solutions of the time-dependent Schrodinger equation allow us to simulate transitions between the quantum states which correspond to the subsequent stages of the gates operation. The performed time-dependent simulations are a test of realizability of the quantum controlled-not gate in the nanodevice 关键词: electronic engineering computing;logic gates;quantum computing;Schrodinger equation;semiconductor quantum dots;virtual machines;computer simulation;quantum controlled-not gate;coupled quantum dots;quantum state transitions;microwave π-pulse;time-dependent Schrodinger equation;time-dependent simulations;nanodevice
