Manifolds of exceptional points and effective Zeno limit of an open two-qubits system

Year: 2025

Type: article

Abstract: Analytical investigations of the Liouvillian exceptional point manifolds (LEPM) of a two-qubit open system reveal a phase diagram for effective Zeno transitions at small dissipation. Notably, the fastest relaxation to the non-equilibrium steady state occurs nearby LEPMs associated with the effective Zeno regime.
