Experimental Liouvillian exceptional points in a quantum system without Hamiltonian singularities
Shilan Abo, Patrycja Tulewicz, Karol Bartkiewicz +2
Hamiltonian exceptional points (HEPs) are spectral degeneracies of non-Hermitian Hamiltonians describing classical and semiclassical open systems with losses and/or gain. However,…

Experimental relative entanglement potentials of single-photon states
Josef Kadlec, Karol Bartkiewicz, AntonÃn Äernoch +2
Entanglement potentials (EPs) enable the characterization and quantification of the nonclassicality of single-mode optical fields by measuring the entanglement generated through be…
