无序输运中的量子演化

Quantum evolution in disordered transport

Clemens Gneiting, Franco Nori

摘要:

我们分析了弱无序下量子态的传播。特别地,我们研究了作为量子信息潜在载体的量子态通过无序微扰波导的可靠传输。我们量化波包失真,后向散射和无序引起的失相,这一切都对运输起着积极的作用,并确定可靠传输的条件。我们的分析依赖于处理的整体平均量子态的量子主方程的非平衡动力学。

英文摘要:

We analyze the propagation of quantum states in the presence of weak disorder. In particular, we investigate the reliable transmittance of quantum states, as potential carriers of quantum information, through disorder-perturbed waveguides. We quantify wave-packet distortion, backscattering, and disorder-induced dephasing, which all act detrimentally on transport, and identify conditions for reliable transmission. Our analysis relies on the treatment of the nonequilibrium dynamics of ensemble-averaged quantum states in terms of quantum master equations.
