About Wigner Friend’s and Hardy’s paradox in a Bohmian approach: a comment of “Quantum theory cannot consistently describe the use of itself”

Aurélien Drezet [Show Biography]

Dr. Aurélien Drezet was born in Metz, France, in 1975. He received his Ph.D Degree in experimental physics from the University Joseph Fourier at Grenoble in 2002 where he was working on nano optics and near-field scanning optical microscopy. After 6 years as a post-doc in Austria and France, he is currently head of the Nano-Optics and Forces team at Institut Néel in Grenoble (which belongs to the national scientific research center-CNRS-France which is also associated with the University Joseph Fourier in Grenoble). His activities range from experimental and theoretical plasmonics to near-field scanning optical microscopy in both the classical and quantum regime. He is also strongly involved in scientific works and discussions concerning quantum foundations in general and Bohmian mechanics in particular.

This is an analysis of the recently published article “Quantum theory cannot consistently describe the use of itself” by D. Frauchiger and R. Renner [1]. Here I decipher the paradox and analyze it from the point of view of de Broglie-Bohm hidden variable theory (i.e., Bohmian mechanics). I also analyze the problem from the perspective obtained by the Copenhagen interpretation (i.e., the Bohrian interpretation) and show that both views are self consistent and do not lead to any contradiction with a `single-world’ description of quantum theory.
