论文摘要

变形的振荡器允许对标准费米子和玻色子进行概括,即用于描述para粒子。这种粒子虽然本质上难以置信,但可以代表良好的候选物,以描述物质的拓扑阶段。在这里,我们通过将para粒子状态映射到量子寄存器状态来报告对para粒子振荡器的数字量子模拟,这使我们能够将para粒子振荡器汉密尔顿(Hamiltonian)识别为$ xy $型号,并将系统进一步将系统数字化到一组通用的门集上。在这两种情况下,栅极深度都随使用的Qubits数量而生长。为了确定结果的有效性,我们通过实验模拟了Para-Fermions和Para-Bosons的动力学,从而证明了对量子计算机上的Para-parpicle振荡器的完全控制。此外,我们比较了驱动Para-Fermi振荡器动力学的数字模拟的总体性能与最近的模拟量子模拟结果。

Deformed oscillators allow for a generalization of the standard fermions and bosons, namely, for the description of para-particles. Such particles, while indiscernible in nature, can represent good candidates for descriptions of physical phenomena like topological phases of matter. Here, we report the digital quantum simulation of para-particle oscillators by mapping para-particle states to the state of a qubit register, which allow us to identify the para-particle oscillator Hamiltonian as an $XY$ model, and further digitize the system onto a universal set of gates. In both instances, the gate depth grows polynomially with the number of qubits used. To establish the validity of our results, we experimentally simulate the dynamics of para-fermions and para-bosons, demonstrating full control of para-particle oscillators on a quantum computer. Furthermore, we compare the overall performance of the digital simulation of dynamics of the driven para-Fermi oscillator to a recent analog quantum simulation result.
