论文摘要
量子系统的仿真是量子计算机最有前途的应用之一。在本文中，我们提出了一种量子算法，以在带有星形连接图的量子寄存器上对BCS模型进行数字量子模拟，例如，钻石中的彩色中心介绍了。我们展示了如何有效地将问题转化为量子硬件，并仅使用量子位之间的本机交互实现算法。此外，我们讨论了电路的复杂性。我们使用该算法来模拟BCS模型的动力学，通过将其平均场基态置于时间依赖性扰动中。使用经典模拟研究量子模拟算法。
The simulation of quantum systems is one of the most promising applications of quantum computers. In this paper we present a quantum algorithm to perform digital quantum simulations of the BCS model on a quantum register with a star shaped connectivity map, as it is, e.g., featured by color centers in diamond. We show how to effectively translate the problem onto the quantum hardware and implement the algorithm using only the native interactions between the qubits. Furthermore we discuss the complexity of the circuit. We use the algorithm to simulate the dynamics of the BCS model by subjecting its mean-field ground state to a time-dependent perturbation. The quantum simulation algorithm is studied using a classical simulation.
