Lee Smolin discusses cosmological inflation, the problem of initial conditions, and the interpretation of the "wavefunction of the universe." Lev Vaidman provides a review of the two state vector formalism, which considers backwards-evolving quantum states. Noriyuki Hatakenaka presents a new scheme for testing macrorealism without statistical treatments by combining Leggett-Garg and Greenberger-Horne-Zeilinger (GHZ) inequalities, i.e. a temporal GHZ test using quantum correlations in time. Lucian Ionescu outlines an "upgrade" of the Feynman path integral formalism – where qubits, instead of complex amplitudes – are associated within elementary transitions of a causal network structure.
The conference is first in a series of foundations conferences organized under joint collaboration between the Perimeter Institute and three Australian national universities.
