Biography

Lucien Hardy is a researcher at Perimeter Institute whose work focuses on Quantum Foundations. He received his PhD from Durham University in 1992 and has held various lecturing positions in Europe. Hardy is known for establishing Hardy's theorem, which provided a simple proof of non-locality in quantum theory. His contributions also include reconstructing Quantum Theory based on a set of five axioms motivated by information-theoretic foundations. Notably, he introduced the concept of indefinite causal structures that have implications for operational theories in Quantum Foundations. He has developed frameworks for quantum theories within the realm of General Relativity and Quantum Gravity, and has made notable strides in diagrammatic calculus and operational reformulations of both Quantum Theory and General Relativity. His ongoing research addresses compositions in physics and explores the implications of causality in operational Quantum Field Theory, particularly regarding the influence of space-time regions on quantum fields. Hardy has received several grants, including the Quantum Information Structure Spacetime Grant from the John Templeton Foundation from 2022 to 2025, highlighting his significant contribution to the field. His recent publications include various papers on quantum interferometers, causaloid frameworks, and other foundational topics in quantum physics.
