We study the effect of the carrier-envelope-phase (CEP) on the high harmonic generation (HHG) from a quantum ring driven by two short orthogonal lasers polarized along the x and y axes. In particular, by varying only the phase of the laser polarized along y it is possible to control the intensity of the emitted harmonics. In fact, we show that the system can efficiently emit harmonics if the laser polarized along y is small and that the cut-off of the spectra can be controlled by changing the phase or the intensity ratio between the two lasers. The wavelet analysis of the emitted harmonics and the time dependence of the angular momentum and of the energy acquired by the electron show that the electron has several main angular momentum variations that generate the cut-off harmonics in as many pulses. These results may have a significant technological impact in computer technology to store information. The implementation of a logical gate that exploits the different temporal locations of the pulses is discussed.

激光驱动量子环：一字节逻辑门实现

我们研究了载流子包络相位 (CEP) 对由沿x 轴和y轴偏振的两个短正交激光器驱动的量子环产生的高次谐波 (HHG) 的影响。特别是，通过仅改变沿y偏振的激光的相位，可以控制发射的谐波的强度。事实上，我们表明，如果沿y偏振的激光较小，系统可以有效地发射谐波，并且可以通过改变两个激光之间的相位或强度比来控制光谱的截止。发射谐波的小波分析以及角动量和电子获得的能量的时间依赖性表明，电子具有几个主要的角动量变化，它们在许多脉冲中产生截止谐波。这些结果可能会对计算机技术存储信息产生重大的技术影响。讨论了利用脉冲的不同时间位置的逻辑门的实现。
