摘要翻译:
任意子是生活在二维中的奇异准粒子,它不属于通常的费米子和玻色子范畴,但服从一种新形式的分数统计。根据最近的一项建议[Phys.Rev.Lett.98,150404(2007)],我们用光子量子模拟器对Kitaev自旋晶格模型中任意子的分数统计量进行了实验证明。我们动态地创建Kitaev模型哈密顿量的基态和激发态(即六个量子比特的图态),并通过单量子比特旋转实现任意子编织和融合操作。观察到一个与任意子编织有关的相移,证实了阿贝尔1/2-任意子分数统计量的预测。

英文摘要:
Anyons are exotic quasiparticles living in two dimensions that do not fit into the usual categories of fermions and bosons, but obey a new form of fractional statistics. Following a recent proposal [Phys. Rev. Lett. 98, 150404 (2007)], we present an experimental demonstration of the fractional statistics of anyons in the Kitaev spin lattice model using a photonic quantum simulator. We dynamically create the ground state and excited states (which are six-qubit graph states) of the Kitaev model Hamiltonian, and implement the anyonic braiding and fusion operations by single-qubit rotations. A phase shift of $\pi$ related to the anyon braiding is observed, confirming the prediction of the fractional statistics of Abelian 1/2-anyons.
