摘要

Abstract 我们通过直接概括之前发现的 \(d=2\) 的解来构建杨-巴克斯特方程在任意维度 \(d\ge 2\) 的解。我们使这些解具有单元性和纠缠性。由于具有单元性，它们可以转化为基于量子系统的量子逻辑门。纠缠特性使得这些解中的每一个，连同所有的（1）-量子门，构成了一组通用的量子逻辑门。

Yang–Baxter equation in all dimensions and universal qudit gates

We construct solutions of the Yang–Baxter equation in any dimension \(d\ge 2\) by directly generalizing the previously found solutions for \(d=2\). We equip those solutions with unitarity and entangling properties. Being unitary, they can be turned into \(2\)-qudit quantum logic gates for qudit-based systems. The entangling property enables each of those solutions, together with all \(1\)-qudit gates, to form a universal set of quantum logic gates.
