摘要:

非阿贝尔规范理论是我们理解自然界基本力的基础,在快速发展的量子模拟领域,开发量身定制的量子硬件和算法来模拟它们是一个突出的挑战。在这里,我们采取的方法,规范场,在时空中离散,表示qudits和时间演化的特罗特步骤与多qudit量子门。这自然地和硬件有效地映射到基于Rydberg镊子阵列的架构,其中长寿命的内部原子状态表示量子比特,并且所需的量子门被执行为由Rydberg封锁机制支持的完整操作。我们说明了我们的建议,SU(2)规范场的最小数字化,展示了显着减少电路深度和门错误相比,传统的基于量子位的方法,这使得NISQ设备的范围内的非阿贝尔规范理论的模拟。

英文摘要:

Non-abelian gauge theories underlie our understanding of fundamental forces in nature, and developing tailored quantum hardware and algorithms to simulate them is an outstanding challenge in the rapidly evolving field of quantum simulation. Here we take an approach where gauge fields, discretized in spacetime, are represented by qudits and are time-evolved in Trotter steps with multiqudit quantum gates. This maps naturally and hardware-efficiently to an architecture based on Rydberg tweezer arrays, where long-lived internal atomic states represent qudits, and the required quantum gates are performed as holonomic operations supported by a Rydberg blockade mechanism. We illustrate our proposal for a minimal digitization of SU(2) gauge fields, demonstrating a significant reduction in circuit depth and gate errors in comparison to a traditional qubit-based approach, which puts simulations of non-abelian gauge theories within reach of NISQ devices.
