A note on the inner products of pure states and their antidistinguishability. (arXiv:2206.08313v1 [quant-ph]) 上午11:01 | Vincent Russo, Jamie Sikora | quant-ph updates on arXiv.org A set of d quantum states is said to be antidistinguishable if there exists a d-outcome POVM that can perfectly identify which state was not measured. A conjecture by Havl\’i\v{c}ek and Barrett states that if… Read more →

Causality, unitarity and stability in quantum gravity: a non-perturbative perspective. (arXiv:2206.04072v1 [hep-th]) 上午9:50 | gr-qc updates on arXiv.org Authors: Alessia Platania Resumming quantum fluctuations at the level of the gravitational path integral is expected to result in non-local effective actions and thus in a non-trivial momentum dependence of the propagator. Which properties the (dressed) graviton propagator has to satisfy and whether… Read more →

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.
