| 摘 要： | 构造了2个强度相同位相不同的激发相干态的叠加态,并通过数值计算研究了该叠加态的反聚束效应和振幅平方压缩效应随激发光子数m、光场强度x和相位差θ的变化,结果表明:随激发光子数m和光场强度x增大,该量子态的振幅平方压缩均会加深;压缩效应与相位差θ有密切的关系;随光场强度x的增大和激发光子数m的增大,其反聚束效应减弱.

| Abstract: | The superposition of two excited coherent states with identical intensity and different phases are constructed. Its antibunching effect and amplitude-squared squeezing are studied numerically. The result shows that as the light intensity and the excited photon number increase, the antibunching effect decreases and the amplitude-squared squeezing increases. The amplitude-squared squeezing is influenced by the phase difference. |
