Description
Holography suggests that gravitational theory can be described by a quantum field theory in one lower dimension. This idea provides an invaluable framework to explore the nature of quantum gravity. In this talk, I will review the basic concepts of holography and highlight recent progress in understanding quantum gravity on anti-de Sitter spacetimes, including the roles of quantum entanglement in shaping spacetime. Then, I will introduce my work which proposes a holographic duality between three-dimensional de Sitter spaces and two-dimensional conformal field theories.
