Nonlocal action in Everettian Quantum Mechanics
Mordecai Waegell, Kelvin J. McQueen
According to a common view, Everettian quantum mechanics (EQM) is a local theory because it avoids nonlocal action at a distance, and this is an important point in EQM's favor. Unl…

Agency cannot be a purely quantum phenomenon
Emily C. Adlam, Kelvin J. McQueen, Mordecai Waegell
What are the physical requirements for agency? We investigate whether a purely quantum system (one evolving unitarily in a coherent regime without decoherence or collapse) can sati…

From statistical dependence to the space of possible superdeterministic theories
Mordecai Waegell, Kelvin J. McQueen
Bell's theorem demonstrates that any physical theory that is consistent with the predictions of quantum mechanics, and which satisfies some apparently innocuous assumptions, must v…
