摘要:

提出了一种基于光谱学的量子计算机求解本征值问题的新方法。该方法的工作原理是将一个“探针”量子位耦合到一组系统模拟量子位,然后在哈密顿动力学下对探针和系统进行时间演化。通过这种方式,我们在量子计算机上模拟光谱学。我们测试我们的方法在IBM量子硬件上的一个简单的单自旋模型和相互作用的Kitaev链模型。对于Kitaev链,我们跟踪出的伪拓扑相边界的两个网站模型。

英文摘要:

We present a novel method for solving eigenvalue problems on a quantum computer based on spectroscopy. The method works by coupling a "probe" qubit to a set of system simulation qubits and then time evolving both the probe and the system under Hamiltonian dynamics. In this way, we simulate spectroscopy on a quantum computer. We test our method on the IBM quantum hardware for a simple single spin model and an interacting Kitaev chain model. For the Kitaev chain, we trace out the pseudo-topological phase boundary for a two-site model.
