摘要
A mechanism of spin decoherence caused by spacetime curvature in general relativity is discussed. The spin state of a particle is shown to decohere only if 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.
