Ryszard Horodecki is a Polish physicist and mathematician known for his contributions to quantum information theory and related fields. He has made significant advancements in understanding quantum entanglement, quantum states, and the mathematical foundations of quantum mechanics. Horodecki is particularly recognized for his work on the Horodecki family of criteria for separability, which addresses the question of whether a given quantum state can be decomposed into a mixture of product states or if it is entangled.
