A consistent theory of quantum gravity will require a fully quantum formulation of the classical equivalence principle. Such a formulation has been recently proposed in terms of the equality of the rest, inertial and gravitational mass operators, and for non-relativistic particles in a weak gravitational field. In this work, we propose a generalization to a fully relativistic formalism of the quantum equivalence principle, valid for all background space-times, as well as for massive bosons and fermions. The principle is trivially satisfied for massless particles. We show that if the equivalence principle is broken at the quantum level, it implies the modification of the standard Lorentz transformations in flat space-time and a corresponding modification of the metric in curved space-time by the different mass ratios. In other words, the observed geometry would effectively depend on the properties of the test particle. Testable predictions of potential violations of the quantum equivalence principle are proposed.

In 1935, Einstein, Podolsky, and Rosen claimed the incompleteness of quantum mechanics by assuming that local actions cannot influence the elements of reality in a distant location. Very much to the contrary, in this Letter we show that via quantum operations performed in her location, Alice can change the reality of observables in the distant laboratory of Bob. We propose a modified optical quantum eraser experiment that can be implemented using current technology for verifying our theoretical predictions, without any need for retrodiction. We demonstrate such an experiment using IBM quantum computers.

Forty years ago, Laughlin explained the newly discovered fractional quantum Hall effect by proposing his famous wave function. He predicted the existence of anyons, particles with fractional charge, obeying fractional statistics. The fractional charge was confirmed almost thirty years ago, while the fractional statistics was observed only a few years back. In this paper, the authors focus on yet another fundamental property of the anyons, namely their spin. They derive a “spin-statistics relation” for anyons in fractional quantum Hall states, directly from the microscopic theory. This relation is a generalization of the fundamental “spin-statistics relation” that all ordinary particles obey.
