Abstract
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.
