Spin Decoherence in a Gravitational Field
arXiv:quant-ph/0509185 · doi:10.1142/9789812773210_0065
Abstract
We discuss a mechanism of spin decoherence in gravitation within the framework of general relativity. The spin state of a particle moving in a gravitational field is shown to decohere due to the curvature of spacetime. As an example, we analyze a particle going around a static spherically-symmetric object.
