This[1] recent open access review article about Liouvillian exceptional points gives some details. From the abstract: Since the Liouvillian exceptional points widely exist in quantum systems such as the atomic vapors, superconducting qubits, and ultracold ions and atoms, they have received increasing amount of attention of late. Here, we present a brief review on an important aspect of the dynamic consequence of Liouvillian exceptional points, namely the chiral state transfer induced by the parametric encircling the Liouvillian exceptional points. That said this is way too far into the quantum weeds for me to grasp. [1]: https://link.springer.com/article/10.1007/s43673-024-00129-3 https://link.springer.com/article/10.1007/s43673-024-00129-3
