Abstract

Producing entanglement in finite-dimensional Hilbert spaces, such as multi-qubit systems, is an important task in quantum computing. A famous example of "entangling operator" -- the Bell matrix -- is known to satisfy the Yang-Baxter Equation and hints at a possible connection between topological and quantum entanglement. This connection can also be seen in a similarity between GHZ states of three qubits and the Borromean rings. The GHZ matrices satisfy a generalized Yang-Baxter Equation (gYBE), which is notoriously difficult to solve. I will show how using supersymmetry in 0+1 dimensions, one can generate a profusion of solutions to the gYBE and provide convincing evidence for the connection mentioned above.
