摘要:

我们提出了一个量子经典算法,在IBM的量子计算机上研究两个空间位置的Schwinger模型的动力学。使用旋转对称性、总电荷和宇称,执行计算所需的量子位数量减少了一个因子$\sim 5$,从而从Hilbert空间中去除了指数级大的非物理扇区。我们的工作开辟了一条途径,探索其他晶格量子场论,如量子色动力学,经典计算是用来找到对称部门,量子计算机评估量子涨落的动力学。

英文摘要:

We present a quantum-classical algorithm to study the dynamics of the two-spatial-site Schwinger model on IBM's quantum computers. Using rotational symmetries, total charge, and parity, the number of qubits needed to perform computation is reduced by a factor of $\sim 5$, removing exponentially-large unphysical sectors from the Hilbert space. Our work opens an avenue for exploration of other lattice quantum field theories, such as quantum chromodynamics, where classical computation is used to find symmetry sectors in which the quantum computer evaluates the dynamics of quantum fluctuations.
