量子關(guān)聯(lián)從雙模光場(chǎng)到電子干涉器件轉(zhuǎn)移的研究
摘 要：通過(guò)對(duì)雙模壓縮態(tài)光場(chǎng)和兩個(gè)電子干涉器件相互作用的研究，得到了兩個(gè)電子干涉器件中電子密度的關(guān)聯(lián)，并采用歸1化關(guān)聯(lián)函數(shù)來(lái)描述這種關(guān)聯(lián)，發(fā)現(xiàn)通過(guò)選擇合適的初始相位差，量子關(guān)聯(lián)可以很好地從雙模壓縮態(tài)光場(chǎng)轉(zhuǎn)移到電子。

The transfer of quantum correlation from two-mode squeezed vacuum field to two electron interference devices
Abstract: Through investigating the interaction between the two-mode squeezed vacuum field and two electron interference devices, and using the normalized correlation function to describe the correlation, we find that the quantum correlation can be transferred to the electron density from the field efficiently by choosing the initial phase difference appropriately.
Key words: two-mode squeezed vacuum state; normalized correlation function; quantum correlation
