Razieh Annabestani, Brajesh Gupt, Bhaskar Roy Bardhan

摘要:

研究了自旋伊辛模型的玻色表示及其在连续变量量子处理器模拟二能级系统中的应用。我们将自旋系统的时间演化分解为一系列连续变量逻辑门,并分析了它们的结构。我们给出了量子线路随自旋晶格系统尺寸变化的估计。此外,我们还讨论了利用高斯玻色子取样装置来估计伊辛哈密顿量的基态能量的可能性。这一结果在发展经典-量子混合算法,如连续变量形式的变分量子本征求解器等方面具有潜在的应用价值。

英文摘要:

We study Bosonic representation of spin Ising model with the application of simulating two level systems using continuous variable quantum processors. We decompose the time evolution of spin systems into a sequence of continuous variable logical gates and analyze their structure. We provide an estimation of quantum circuit scaling with the size of the spin lattice system. Furthermore, we discuss the possibility of using a Gaussian Boson sampling device to estimate the ground state energy of Ising Hamiltonian. The result has potential application in developing hybrid classical-quantum algorithms such as continuous variable version of variational quantum eigensolver.
