通过相对论场传输量子比特

Transmitting qubits through relativistic fields

Robert H. Jonsson, Katja Ried, Eduardo Martin-Martinez, Achim Kempf

摘要:

无线通信从多个方向上的信号的同时发射获得其功率。然而,在量子通信的背景下,这种现象必须与不可克隆原则仔细调和。在此背景下,我们研究了如何通过相对论场实现量子信息的无线通信。为此,我们扩展了现有的框架,以允许非微扰描述,例如,量子态转移。我们考虑,特别是,1+1时空维度的情况下,它已经允许一些有趣的情况下,指向,例如,类似于量子秘密共享的任务的新方法。

英文摘要:

Wireless communication derives its power from the simultaneous emission of signals in multiple directions. However, in the context of quantum communication, this phenomenon must be reconciled carefully with the no-cloning principle. In this context, we here study how wireless communication of quantum information can be realized via relativistic fields. To this end, we extend existing frameworks to allow for a non-perturbative description of, e.g., quantum state transfer. We consider, in particular, the case of 1+1 spacetime dimensions, which already allows a number of interesting scenarios, pointing to, for example, new methods for tasks similar to quantum secret sharing.
