论文摘要
重新归一化的群体思想和有效的操作员用于有效地确定数字量子设备上非相互作用标量场理论基础状态的局部单位。通过这些方法，可以使用小空间体积中的经典计算的基态来确定在超古典量子寄存器中准备基础状态的操作员，即使是用于相互作用的标量场理论。由于相关函数的指数衰减和数字化伪像的双重指数抑制，因此衍生的量子电路有望与近期量子设备相关。
Renormalization group ideas and effective operators are used to efficiently determine localized unitaries for preparing the ground states of non-interacting scalar field theories on digital quantum devices. With these methods, classically computed ground states in a small spatial volume can be used to determine operators for preparing the ground state in a beyond-classical quantum register, even for interacting scalar field theories. Due to the exponential decay of correlation functions and the double exponential suppression of digitization artifacts, the derived quantum circuits are expected to be relevant already for near-term quantum devices.
