论文摘要
我们研究了一个均匀加速的检测器，该检测器耦合到无质量标量场以进行有限的时间间隔。通过考虑最初以叠加态制备的检测器，即Qubit状态，我们发现加速度会诱导量子的脱谐。我们的结果表明，连贯性丧失对Qubit状态的极角对Bloch球的极角和时间相互作用的依赖性。调整这些参数可以显着改善条件，以估计因异型辐射引起的分解程度。
We study a uniformly accelerated detector coupled to a massless scalar field for a finite time interval. By considering the detector initially prepared in a superposition state, qubit state, we find that the acceleration induces decoherence on the qubit. Our results suggest the dependence of loss of coherence on the polar angle of qubit state on a Bloch sphere and the time interaction. The adjust those parameters can significantly improve the conditions to estimate the degree of decoherence induced by Unruh radiation.
