Lucien Hardy (born 1966) is a theoretical physicist, known for his work on the foundation of quantum physics including Hardy's paradox, a thought experiment he devised in 1992, and his widely cited 2001 axiomatic reconstruction of quantum theory that led to a surge of papers in this area.
In the course of his career he has performed research and lecturing in various universities in Europe. In 1992, he became lecturer in mathematical physics at Maynooth College, The National University of Ireland, subsequently he was a Royal Society postdoctoral fellow at the University of Innsbruck, Austria, lecturer in Mathematical Sciences Department at the University of Durham, UK, and a postdoctoral fellow at La Sapienza University in Rome, Italy.
Starting in 1997, he was a Royal Society university research fellow for five years at the University of Oxford.
