摘要:

由量子系统的循环演化产生的几何相位为推进基础物理学和技术提供了一个鼓舞人心的舞台。有趣的是,在物理系统中实现的任意子的奇异统计可以被解释为几何相位的拓扑版本。然而,非阿贝尔统计尚未在实验室中得到证明。在这里,我们采用了一个全光量子系统,模拟统计演化的马约拉纳费米子。其结果是,我们实验实现非阿贝尔Berry相位的拓扑特性,他们是不变的,根据其控制参数的连续变形。我们实现了一个通用的一套马约拉纳启发门进行拓扑和非拓扑的演变,并调查他们的弹性对扰动错误。我们的光子实验,虽然它是不可扩展的,它表明了有趣的可能性,实验模拟马约拉纳统计与可扩展的技术。

英文摘要:

Geometric phases, generated by cyclic evolutions of quantum systems, offer an inspiring playground for advancing fundamental physics and technologies, alike. Intriguingly, the exotic statistics of anyons realised in physical systems can be interpreted as a topological version of geometric phases. However, non-Abelian statistics has not yet been demonstrated in the laboratory. Here we employ an all optical quantum system that simulates the statistical evolution of Majorana fermions. As a result we experimentally realise non-Abelian Berry phases with the topological characteristic that they are invariant under continues deformations of their control parameters. We implement a universal set of Majorana inspired gates by performing topological and non-topological evolutions and investigate their resilience against perturbative errors. Our photonic experiment, while it is not scalable, it suggests the intriguing possibility of experimentally simulating Majorana statistics with scalable technologies.
