Michał Horodecki

Short description: Polish physicist

Michał Horodecki (born 1973[1]) is a Polish physicist at the University of Gdańsk working in the field of quantum information theory, notable for his work on entanglement theory.[2]

He co-discovered the Peres-Horodecki criterion for testing whether a state is entangled,[3] and used it to find bound entanglement together with his brother Paweł Horodecki and father Ryszard Horodecki. He co-discovered with Jonathan Oppenheim, Paweł Horodecki and Karol Horodecki that secret key can be drawn from some bound entangled states. Together with Fernando Brandao he proved that every one-dimensional quantum state with a finite correlation length obeys an area law for entanglement entropy. Together with Jonathan Oppenheim and Andreas Winter, he discovered quantum state-merging and used this primitive to show that quantum information could be negative.

2015 he was awarded the Minister of Science and Higher Education Awards of the Polish government.[4]
