Mioara Mugur-Schächter

Mioara Mugur-Schächter (, born 1929 ) is a French-Romanian physicist specialized in the foundations of quantum mechanics, probability theory, and theory of communication of information. She is also an epistemologist. In her PhD thesis "Étude du caractère complet de la théorie quantique", she worked a formal argument to invalidate John von Neumann's no hidden variables proof, published in 1964, Her refutation was inspired by previous work by Paulette Destouches-Février on von Neumann's proof.

In the 1990s she organized a working group (Centre d'études pour la synthèse d'une épistémologie formelle) in French epistemological circles and edited a book collecting epistemologic studies including contributions from notable figures such as , Her work has been described as a form of relativistic quantum logic, a way of combining the concepts of Hilbert space and Lorentzian spacetime to create a quantum logic subject to special relativity but with explicit concepts of signaling.

In 2011, Mugur-Schächter organized a debate on the concepts of randomness, statistics and probability with Maria Luisa Dalla Chiara, Cristian Calude, Giuseppe Longo and Cristian Calude, that was published as part of a special issue of Mathematical Structures in Computer Science.
