狭义相对论调制的量子退相干

Quantum Decoherence Modulated by Special Relativity

Jian-Ming Cai, Zheng-Wei Zhou, Ye-Fei Yuan, Guang-Can Guo

摘要:

通过研究自旋为1/2的Dirac电子在背景磁噪声作用下的演化,我们证明了狭义相对论的作用会显著地改变自旋态的退相干性质.退相可以被大大抑制,并且在足够长的时间内,退相干甚至似乎停止。这一有趣的现象源于狭义相对论诱导的修饰环境。

英文摘要:

By investigating the evolution of a moving spin-1/2 Dirac electron coupled with a background magnetic noise, we demonstrate that the effects of special relativity will significantly modify the decoherence properties of the spin state. The dephasing could be much suppressed, and for a sufficiently long time the decoherence even seems to halt. This interesting phenomenon stems from the dressed environment induced by special relativity.
