摘要:

任意子是一种服从分数统计的奇异准粒子,其行为可以在人工设计的自旋系统中模拟。在这里,我们提出了一个在由四个量子比特组成的超导电路中产生任意子激发的实验模拟,通过动态产生环面码模型的基态和激发态来实现,即,Greenberger-Horne-Zeilinger表示。任意子编织是通过单量子比特旋转实现的:通过拉姆齐型干涉测量观察到与编织相关的π相移,这是阿贝尔1/2任意子的标志。

英文摘要:

Anyons are exotic quasiparticles obeying fractional statistics,whose behavior can be emulated in artificially designed spin systems.Here we present an experimental emulation of creating anyonic excitations in a superconducting circuit that consists of four qubits, achieved by dynamically generating the ground and excited states of the toric code model, i.e., four-qubit Greenberger-Horne-Zeilinger states. The anyonic braiding is implemented via single-qubit rotations: a phase shift of πrelated to braiding, the hallmark of Abelian 1/2 anyons, has been observed through a Ramsey-type interference measurement.
