The Tracy-Singh product of matrices permits to construct a new gate $c \boxtimes c'$ from two $2$-qudit gates $c$ and $c'$. If $c$ and $c'$ are both Yang-Baxter gates, then $c \boxtimes c'$ is also a Yang-Baxter gate, and if at least one of…

Unitary braiding operators can be used as robust entangling quantum gates. We introduce a solution-generating technique to solve the $(d,m,l)$-generalized Yang-Baxter equation, for $m/2\leq l \leq m$, which allows to systematically…
Entangled states, such as the Bell and GHZ states, are generated from separable states using matrices known to satisfy the Yang-Baxter equation and its generalization. This remarkable fact hints at the possibility of using braiding…

Most quantum computing architectures to date natively support multi-valued logic, albeit being typically operated in a binary fashion. Multi-valued, or qudit, quantum processors have access to much richer forms of quantum entanglement,…
