真空涨落的新结果:量子场中加速探测器与惯性探测器的比较

New results on vacuum fluctuations: Accelerated detector versus inertial detector in a quantum field

I-Chin Wang

摘要:

我们研究了运动的探测器与量子场的相互作用,特别是当探测器在量子场中运动时,探测器的运动轨迹对真空涨落的影响(Unruh效应)。我们重点研究了双运动探测器系统在量子隐形传态中的应用。我们发现匀加速探测器在Rindler空间中的运动轨迹不能推广到匀速运动的轨道。在前人工作的基础上,我们重新计算了一次,发现以前的计算中少了一项,并且发现解中参数的取值有一定的限制。此外,如果不包括缺失项,惯性检测器的量子场方差将为零,并且在这样的系统中是不可能的。当所有这些点被组合时,在早期区域中惯性检测器和加速检测器之间的两点关联函数中存在差异。在两点关联函数中可以看到固有加速度的影响。这可能在量子隐形传态过程中发挥作用,值得深入研究。

英文摘要:

We investigate the interaction between a moving detector and a quantum field, especially about how the trajectory of the detector would affect the vacuum fluctuations when the detector is moves in a quantum field (the Unruh effect). We focus on two moving detectors system for future application in quantum teleportation. We find that the rajectory of a uniformly accelerated detector in Rindler space cannot be extended to a trajectory in which a detector moves at constant velocity. Based on our previous work, we redo the calculations and find that a term is missing from the past calculations, and we also find that there are some restrictions on the values for the parameters in the solutions. In addition, without inclusion of the missing term, the variance from the quantum field for the inertial detector will be zero and is unlikely in such a system. When all these points are combined, there is a difference in the two-point correlation function between the inertial detector and the accelerated detector in the early-time region. The influence of proper acceleration can be seen in the two-point correlation functions. This might play a role in the quantum teleportation process and be worth studying thoroughly.
