论文摘要
近年来，通用量子计算机的开发取得了巨大的成功，最终达到了Google报道的量子至上。现在可以用数十个Qubits实施短深度量子电路，并获得具有明显的保真度的结果。量子步行是可在可用量子计算机上实施的好候选者。在这项工作中，我们在循环，二维晶格上使用一个和两个相互作用的步行者实施离散的量子步行，并在IBM量子计算机上完成图形。我们能够使用循环，二维晶格以及每个节点的完整图获得有意义的结果，每个节点需要4 Quit的量子电路，最高为深度100。
The development of universal quantum computers has achieved remarkable success in recent years, culminating with the quantum supremacy reported by Google. Now is possible to implement short-depth quantum circuits with dozens of qubits and to obtain results with significant fidelity. Quantum walks are good candidates to be implemented on the available quantum computers. In this work, we implement discrete-time quantum walks with one and two interacting walkers on cycles, two-dimensional lattices, and complete graphs on IBM quantum computers. We are able to obtain meaningful results using the cycle, the two-dimensional lattice, and the complete graph with 16 nodes each, which require 4-qubit quantum circuits up to depth 100.
