Abstract摘要
Over the past twenty years, fruitful developments on the interface between quantum information theory, quantum field theory, and quantum gravity are achieved in the framework of the AdS/CFT correspondence. A long-standing and intriguing question is: does the holographic principle apply to cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime which is closed by a timelike boundary. By employing the holographic entanglement entropy, we argue that gravity on a half dS$_{d+1}$ is dual to a highly non-local field theory without gravity on dS$_d$.
