Samuel Leon Braunstein (born 1961) is a professor at the University of York, England. He is a member of a research group in non-standard computation and has a particular interest in quantum information, quantum computation, and black hole thermodynamics. Braunstein has written or edited three books and has published more than 140 papers, which have been cited over 32,000 times. His most important work is on quantum teleportation, and published in a paper titled Unconditional Quantum Teleportation. The paper has been cited more than 3,000 times and received significant coverage in both the scientific and mainstream press. In February 2006, Braunstein made the news due to his involvement in the first successful demonstration of quantum telecloning.From 2009, he began to research black hole thermodynamics, significantly contributing to the black hole information paradox and the firewall paradox.Braunstein co-authored papers with Gilles Brassard and Simone Severini, with whom he introduced the Braunstein-Ghosh-Severini Entropy of a graph.
