We experimentally demonstrate the phase control of the controlled-NOT using dressing field in a hot atomic ensemble. This is more convenient for modulating the controlled-NOT gate with various relative phases. Moreover, with the phase modulated by changing the angle between the probe field and the dressing field, the enhanced output signal can be switched to the suppressed state in this logic process. The study performed by such a setup not only possess orbital angular momentum characteristics but can also be extended to handle quantum information processing in atom vapor.

使用原子蒸气修整场的受控非门的相位控制

我们通过实验证明了在热原子系综中使用修整场控制受控非的相位控制。这对于用各种相对相位调制受控非门更方便。此外，通过改变探测场和修整场之间的角度来调制相位，在这个逻辑过程中可以将增强的输出信号切换到抑制状态。通过这种设置进行的研究不仅具有轨道角动量特性，而且还可以扩展到处理原子蒸汽中的量子信息处理。
