论文摘要
我们提出了一种基于光谱学量子计算机上的特征值问题的新方法。该方法是通过将“探针”量子耦合到一组系统模拟量子位,然后在汉密尔顿动力学下的探针和系统演变的时间来起作用。这样,我们在量子计算机上模拟光谱。我们在IBM量子硬件上测试我们的方法,以进行简单的单个旋转模型和相互作用的Kitaev链模型。对于Kitaev链,我们为两个站点模型追踪了伪流相边界。
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.
