About

Dr. Fabio Costa joined Nordita as an Assistant Professor in February 2023. Dr. Costa's research interests encompass foundational and applied topics in quantum physics, including quantum field theory, quantum reference frames, general relativistic effects, and closed time-like curves. His primary research focuses on quantum causal structures and quantum non-Markovianity. He has developed a formulation of quantum theory that eliminates the need for a background causal structure, which allows for the reconstruction of causal relationships from observed data and efficient characterization of multi-time correlations in non-Markovian open systems. His research also involves the study of indefinite causal order and its role in the interplay between quantum theory and general relativity, as well as applications to quantum communication and quantum computation, including experimental proofs of principle.

Dr Costa earned his PhD in quantum foundations from the University of Vienna in 2013 under the supervision of Caslav Brukner. From 2014 to 2023, he worked at the University of Queensland (UQ) in Brisbane, Australia, associated with the research center on Engineered Quantum Systems (EQUS). He currently holds an honorary position at UQ and serves as an Associate Investigator at EQUS.
