量子反转:相干量子吸收体的通用理论

Quantum reversal: a general theory of coherent quantum absorbers

Mankei Tsang

AI总结:

本研究提出了相干量子吸收体的通用理论,通过引入“反转条件”让反转器相干地反转系统对场的影响,并将其严格归结为涉及 Petz 恢复映射和 Kraus 算符的简洁公式,推广并简化了现有处理方法。

摘要:

相干量子吸收体这一引人入胜的概念——它能够吸收另一系统发射的任何光子,同时保持与该系统的纠缠——在开放量子系统理论和量子计量学中产生了广泛的影响。本研究通过为这两个系统提出所谓的反转条件来推广这一概念,在反转条件中,“反转器”相干地反转一个系统对场的任何影响。反转条件被严格归结为涉及 Petz 恢复映射和 Kraus 算符的简洁公式,从而推广并简化了现有的相干吸收体处理方法。

英文摘要:

The fascinating concept of coherent quantum absorber - which can absorb any photon emitted by another system while maintaining entanglement with that system - has found diverse implications in open quantum system theory and quantum metrology. This work generalizes the concept by proposing the so-called reversal conditions for the two systems, in which a "reverser" coherently reverses any effect of the other system on a field. The reversal conditions are rigorously boiled down to concise formulas involving the Petz recovery map and Kraus operators, thereby generalizing as well as streamlining the existing treatments of coherent absorbers.
