We study the dissipative evolution of quantum entanglement and Gaussian interference power in the dynamical Casimir radiation generated in a superconducting waveguide. We consider the decoherence in the current experimental studies, which are in the low temperature. We observe that lower temperature, smaller detuning and larger normalized amplitude can not only maintain the non-classical association of the system more effectively, but also increase the utilization of quantum resources. Moreover, most of the damping is placed on the second noise channel, the entanglement and Gaussian interference power maintain longer and better quality, and they are also more sensitive to other environmental parameters. In addition, the Gaussian interference power is always non-zero, which displays its robustness to the thermal noise and the dissipation.

动态卡西米尔效应中的纠缠和高斯干涉功率

我们研究了超导波导中产生的动态卡西米尔辐射中量子纠缠和高斯干涉功率的耗散演化。我们考虑了当前实验研究中的退相干性，这些研究是在低温下进行的。我们观察到较低的温度、较小的失谐和较大的归一化幅度不仅可以更有效地保持系统的非经典关联，而且还可以提高量子资源的利用率。而且，大部分阻尼都放在第二个噪声通道上，纠缠和高斯干扰功率保持时间更长，质量更好，对其他环境参数也更敏感。此外，高斯干扰功率始终不为零，显示出其对热噪声和耗散的鲁棒性。
