Majorana零模混合轻物质网络
Hybrid light-matter networks of Majorana zero modes
摘要:
拓扑激发,如马约拉纳零模,是编码量子信息的一种有前途的途径。马约拉纳量子比特的拓扑保护门,基于它们的编织,将需要某种形式的网络。在这里,我们建议建立这样一个网络纠缠马约拉纳物质与光在微波腔QED设置。我们的计划利用了光诱导的相互作用,这是普遍的所有马约拉纳纳米级电路平台。这种效应源于物理马约拉纳模式的一维链中的光-物质耦合的参数驱动。我们的设置能够实现马约拉纳量子计算平台所需的所有基本操作,例如融合,编织,关键的T门,读出,以及重要的是,物理马约拉纳模式的稳定或校正。
英文摘要:
Topological excitations, such as Majorana zero modes, are a promising route for encoding quantum information. Topologically protected gates of Majorana qubits, based on their braiding, will require some form of network. Here, we propose to build such a network by entangling Majorana matter with light in a microwave cavity QED setup. Our scheme exploits a light-induced interaction which is universal to all the Majorana nanoscale circuit platforms. This effect stems from a parametric drive of the light-matter coupling in a one-dimensional chain of physical Majorana modes. Our setup enables all the basic operations needed in a Majorana quantum computing platform such as fusing, braiding, the crucial T-gate, the read-out and, importantly, the stabilization or correction of the physical Majorana modes.
