Spin decoherence by spacetime curvature
arXiv:quant-ph/0312064 · doi:10.1088/0305-4470/38/9/013
Abstract
A decoherence mechanism caused by spacetime curvature is discussed. The spin state of a particle is shown to decohere if only the particle moves in a curved spacetime. In particular, when a particle is near the event horizon of a black hole, an extremely rapid spin decoherence occurs for an observer who is static in a Killing time, however slow the particle's motion is.
