Liouvillian Exceptional Points in Quantum Brickwork Circuits
Vladislav Popkov, Mario Salerno
We demonstrate that Liouvillian exceptional points (LEPs), previously explored only in continuous Lindbladian dynamics, also emerge in discrete brickwork completely positive trace-…

Manifolds of exceptional points and effective Zeno limit of an open two-qubit system
Vladislav Popkov, Carlo Presilla, Mario Salerno
We analytically investigate the Liouvillian exceptional point manifolds (LEPMs) of a two-qubit open system, where one qubit is coupled to a dissipative polarization bath. Exploitin…
