Gravitational decoherence

From Wikipedia, the free encyclopedia

Gravitational decoherence is a term for hypothetical mechanisms by which gravitation can act on quantum mechanical systems to produce decoherence. Advocates of gravitational decoherence include Frigyes Károlyházy, Roger Penrose and Lajos Diósi.[1][2]

A number of experiments have been proposed to test the gravitational decoherence hypothesis.[1][3][4]

Dmitriy Podolskiy and Robert Lanza have argued that gravitational decoherence may explain the existence of the arrow of time.[5]
