摘要

我们将注意力集中在作为初始态的三方混合态上,并应用相干协整分别研究了相位阻尼、相位翻转和比特翻转通道下施瓦兹柴尔德黑洞背景下的量子相干特性。在相干并发的基础上,提出了三方子系统的几种分析互补关系。在位翻转通道中,相干一致性的行为与相位阻尼通道类似,可获取的相干一致性总是随着霍金加速度的上升而降低,但从未发生猝死,而不可获取的相干一致性则从零开始单调增加。有趣的是,在相位翻转信道下,相干性先是下降,然后随着衰变概率的上升而上升。与三方纯态的情况不同,X 形混合态的相干一致性等于相干性的 l1 -正态。

Quantum coherence of mixed states under noisy channels in noninertial frames
We focus our attention on tripartite mixed states as initial states, and apply coherence concurrence to investigate quantum coherence properties in the background of a Schwarzschild black hole under phase damping, phase flip and bit flip channels, respectively. Several analytic complementary relationships based on coherence concurrence for tripartite subsystems are proposed. In the case of the bit flip channel, the behavior of the coherence concurrence is similar to the one of the phase damping channel, the accessible coherence concurrence always degrades as the Hawking acceleration rising, but sudden death never occurs, while the inaccessible coherence increases from zero monotonically. Interestingly, the coherence concurrence is decreasing at first and then increasing as the decay probability rising under phase flip channel. Unlike the case of tripartite pure states, the coherence concurrence of mixed state with X shape is equal to l1 -norm of coherence.

期刊介绍: Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
