. He is best known for introducing (together with his father Ryszard Horodecki and brother Michał Horodecki) the Peres-Horodecki criterion for testing whether a quantum state is entangled. Moreover, Paweł Horodecki demonstrated that there exist states which are entangled whereas no pure entangled states can be obtained from them by means of local operations and classical communication (

LOCC LOCC, or local operations and classical communication, is a method in quantum information theory where a local (product) operation is performed on part of the system, and where the result of that operation is "communicated" classically to another ...

). Such states are called bound entangled states. He also showed that even bound entanglement (when used in conjunction with a single pair of free entangled particles) can lead to
