作为幺正性代价的假想纠缠

Imaginary Entanglement as Cost of Unitarity

Constantin V. Usenko

摘要:

这份报告是关于确定纠缠所需的保真度和总是伴随着精确测量的伴随噪声之间的矛盾。场的量子性质的帐户导致额外的噪声所造成的多个粒子的创建通过嵌入部分的空间量子场表示的非幺正性(Unruh噪声)。量子噪声的原因消失在离开假设的统计独立的检测器。探测器的涂抹消除了造成Unruh噪声的原因,并出现了由探测器部分重叠引起的少数模态的虚纠缠。

英文摘要:

This report is about contradiction between fidelity needed to determine the entanglement and concomitant noise that always accompanies precise measurement. Account of quantum properties of field leads to additional noise caused by multiple particle creation through nonunitarity of quantum field representation in embedded sections of space (Unruh noise). Causes of quantum noise vanish at leaving off assumption about statistical independence of detectors. Smearing of detector leads to elimination of causes of Unruh noise and to emergence of imaginary entanglement of few mode states caused by overlap of detector sections.
