论文摘要
变异量子本质量是一种突出的杂种量子古典算法，预计会影响近期量子设备。它们通常基于由参数化的单量门门和固定的两分门组成的电路ANSATZ。我们研究了参数化的两分门在变异量子质量层中的影响。我们使用固定和参数化的两分Qubit Gates在电路ANSATZ中模拟了变异量子本质量算法，并表明，参数化版本在最佳能源和降低异常值时都优于固定版本，用于量子化学和材料科学的一系列汉密尔顿人。
The variational quantum eigensolver is a prominent hybrid quantum-classical algorithm expected to impact near-term quantum devices. They are usually based on a circuit ansatz consisting of parameterized single-qubit gates and fixed two-qubit gates. We study the effect of parameterized two-qubit gates in the variational quantum eigensolver. We simulate a variational quantum eigensolver algorithm using fixed and parameterized two-qubit gates in the circuit ansatz and show that the parameterized versions outperform the fixed versions, both when it comes to best energy and reducing outliers, for a range of Hamiltonians with applications in quantum chemistry and materials science.
