Rupert Ursin (born January 26, 1973) is an Austrian experimental physicist active in the field of quantum entanglement and communications. He is currently deputy director at the Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences.[1]
Education
Ursin completed his Masters diploma in 2001, then in December 2006 completed a PhD dissertation at University of Vienna on quantum teleportation over long distances. He continued with postdoctoral studies in 2007, and since 2013 has served as a research group leader at the IQOQI.[1]
Research
Ursin's research group is active in the field of quantum entanglement and communications. He has contributed to the foundations of quantum physics—demonstrating several examples of loophole-free Bell inequalities—as well as advances in quantum key distribution.[2][3]
The group's interests include the intersection of gravity and quantum physics in microgravity and hypergravity experiments. Ursin is principal investigator for an international effort to bring a quantum physics experiment to the International Space Station[4] and develop quantum applications for space.[5]
In 2004, Ursin and colleagues from the Institute for Experimental Physics at the University of Vienna succeeded in the world's-first demonstration of quantum teleportation of a photon outside of the laboratory, sending it a distance of 600 meters across the River Danube.[6]
In 2007, Ursin succeeded in distributing entangled photons between the Canary Islands La Palma and Tenerife over a world-record distance of 144 km while working together in a collaboration with the European Space Agency (ESA).[7]
In 2012, Ursin joined an international collaboration to propose a novel demonstration of free-space quantum communications at an astronaut training facility near the summit of the Mauna Kea volcano.[8] The team's proposal, “Astronaut Development and Deployment of a Secure Space Communications Network”, became part of an invited submission to the NASA Institute for Advanced Concepts office, then on to the newly-created DARPA Quiness Macroscopic Quantum Communications program.[9][10]
In August 2016, Ursin's group successfully tested entanglement in accelerated reference frames.[11]
