We report on experiments exploring the non-Hermitian dynamics of pairs oftwo-level atoms tightly confined in an optical lattice and driven by anear-resonant laser. Although spontaneous emission is negligible for thelong-lived excited state, two-body dissipation arises from strong inelasticcollisions between two atoms in the excited state. We demonstratequasi-adiabatic control of the internal state of the pairs in the quantum Zenoregime where inelastic losses dominate. Preparing each atom pair in thelongest-lived eigenstate of the non-Hermitian Hamiltonian describing thedissipative dynamics, we measure a lifetime enhanced by more than two orders ofmagnitude in comparison to the bare two-body lifetime. The measured enhancementfactor is in quantitative agreement with the expected lifetime of the prepared``non-Hermitian dressed state''.
