量子位自旋冰
Qubit spin ice
摘要：
人工自旋冰是可以被设计的受抑自旋系统，其中几何和拓扑的微调允许在组分水平上设计和表征奇异的涌现现象。在这里，我们报告的超导量子比特晶格中的自旋冰的实现。与传统的人工自旋冰不同，我们的系统是由量子和热涨落无序的。的基态是经典的冰规则描述，我们实现了控制一个脆弱的简并点，导致库仑相位。钉扎单个自旋的能力使我们能够证明高斯定律在二维中出现的有效单极子。所展示的量子位控制为未来拓扑保护的人工量子自旋液体的潜在研究奠定了基础。
英文摘要：
Artificial spin ices are frustrated spin systems that can be engineered, wherein fine tuning of geometry and topology has allowed the design and characterization of exotic emergent phenomena at the constituent level. Here we report a realization of spin ice in a lattice of superconducting qubits. Unlike conventional artificial spin ice, our system is disordered by both quantum and thermal fluctuations. The ground state is classically described by the ice rule, and we achieve control over a fragile degeneracy point leading to a Coulomb phase. The ability to pin individual spins allows us to demonstrate Gauss's law for emergent effective monopoles in two dimensions. The demonstrated qubit control lays the groundwork for potential future study of topologically protected artificial quantum spin liquids.
