论文摘要
量子处理器使用有效旋转之间的天然相互作用来模拟汉密尔顿人或执行量子门。在大多数处理器中，天然相互作用是成对的，限制了许多量子位之间控制纠缠的效率。在这里，我们在实验中证明了陷阱离子量子位之间的一类新的天然相互作用，将常规的成对相互作用扩展到更高阶。我们将三体和四体旋转相互作用作为示例，表明高阶自旋多项式可以用作量子信息应用的新工具箱。
Quantum processors use the native interactions between effective spins to simulate Hamiltonians or execute quantum gates. In most processors, the native interactions are pairwise, limiting the efficiency of controlling entanglement between many qubits. Here we experimentally demonstrate a new class of native interactions between trapped-ion qubits, extending conventional pairwise interactions to higher order. We realize three- and four-body spin interactions as examples, showing that high-order spin polynomials may serve as a new toolbox for quantum information applications.
