Here, a method to generate and shape the tri‐photon entanglement in the temporal domain via simplified single step of six‐wave mixing processes of hot atomic gas media is proposed. The effect of dressing fields on shaping the tri‐photon temporal waveform is discussed. Cascade double dressing fields will reduce the width of rectangular profile of tri‐photon waveform when compared to the single dressing field. Conversely, nested double dressing fields will widen the width of rectangular profile of tri‐photon waveform. The double dressing field will affect the coherence time of linear optical response. The relationship between phase matching bandwidth and electromagnetically induced transparency bandwidth will decide the shape of temporal waveform and coherence time in linear optical response. The transition of nonlinear optical response to linear optical response can be completed by regulating the dressing fields. The results of this proposed study have potential impact on long‐distance quantum communication, high‐dimensional entanglement, and photon storage.

通过双修整整形三光子的时间波形

在此，提出了一种通过热原子气体介质的六波混合过程的简化单步在时域中生成和成形三光子纠缠的方法。讨论了修整场对整形三光子时间波形的影响。与单修整场相比，级联双修整场将减小三光子波形的矩形轮廓的宽度。相反，嵌套的双修整场将加宽三光子波形的矩形轮廓的宽度。双重修整场将影响线性光学响应的相干时间。相位匹配带宽和电磁感应的透明带宽之间的关系将决定线性光学响应中时间波形的形状和相干时间。非线性光学响应向线性光学响应的过渡可以通过调整修整场来完成。这项拟议研究的结果可能对长距离量子通信，高维纠缠和光子存储产生影响。
