A no-go theorem for the persistent reality of Wigner's friend's perception
P. A. Guérin, V. Baumann, et al.
This groundbreaking paper reveals a no-go theorem that challenges our understanding of reality in quantum mechanics. Conducted by Philippe Allard Guérin, Veronika Baumann, Flavio Del Santo, and Časlav Brukner, it suggests that a single observer's measurements at different times can't coexist in the same reality. What does this mean for our predictions in the quantum realm? Discover the implications of potentially altering the Born rule and the validity of unitary quantum mechanics.
