[4] He earned his PhD under Anton Zeilinger at the University of Vienna in 2002, during which time he performed experiments on Bell's inequality and cryptography with entangled photons.
[9][10] He is also an affiliate of the Perimeter Institute for Theoretical Physics,[11] a fellow of the Canadian Institute for Advanced Research,[1] and CEO and co-founder of quantum optics measurement device company UQDevices alongside physicist Raymond Laflamme.
[13] He is currently "working with partners in industry and academia to advance a proposed microsatellite mission called QEYSSat through a series of technical studies funded initially by Defence Research and Development Canada (DRDC) and subsequently by the Canadian Space Agency (CSA).
"[14] In April 2017, the Canadian government announced funding of $80.9 million to the Canadian Space Agency for funding of two projects, one of which is for the "demonstration of the applications of quantum technology in space" with the goal of positioning "Canada as a leader in quantum encryption".
[19] In June 2017, Jennewein and his colleagues published findings that showed the first demonstration of quantum key distribution from a ground transmitter to a "receiver prototype mounted on an airplane in flight", reporting optical links with distances between 3-10km and the generation of secure keys up to 868 kilobytes in length.
