    "abstract": "A decoherence mechanism caused by spacetime curvature is discussed. The spin\nstate of a particle is shown to decohere if only the particle moves in a curved\nspacetime. In particular, when a particle is near the event horizon of a black\nhole, an extremely rapid spin decoherence occurs for an observer who is static\nin a Killing time, however slow the particle\u0027s motion is.",
