A simple proof that the global phase is real

It is a standard view in quantum mechanics that two wave functions that differ only in the global phase represent the same physical state. In this paper, I argue that this standard view is wrong and the global phase is real in psi-ontic theories such as the de Broglie Bohm theory, the many-worlds interpretation and collapse theories of quantum mechanics.

Quantum Mysteries for No One?

Attached is our comment on the paper by Frank Lad, “Quantum Mysteries for No One” in Journal of Modern Physics (July 2021). Lad’s paper claims to refute Mermin’s result in, “Quantum Mysteries for Anyone” in Journal of Philosophy (1981). [Also published as, “Bringing home the atomic world: Quantum mysteries for anybody” in American Journal of Physics (1981).] While Lad may… Read more →

Entanglement, Complexity, and Causal Asymmetry in Quantum Theories. (arXiv:2204.06742v1 [physics.hist-ph]) 上午8:51 | Porter Williams | quant-ph updates on arXiv.org It is often claimed that one cannot locate a notion of causation in fundamental physical theories. The reason most commonly given is that the dynamics of those theories do not support any distinction between the past and the future, and this… Read more →
