Abstract
Solutions to the Yang-Baxter equation yield representations of braid groups. Under certain conditions, identified by Turaev, traces of these representations yield link invariants. The matrices satisfying the Yang-Baxter equation, if unitary, can be interpreted as quantum gates. Here we show that if the gate is non-entangling, then the resulting invariant of knots is trivial. Thus we obtain a connection between topological entanglement and quantum entanglement, as proposed by Kauffman et al..Citation
