Abstract:
Holographic Principle asserts an equivalence between quantum systems with objects in gravitational fields in a higher dimensional spacetime. The suggestion of holography originated from the work of Hawking, Bekenstein and others on the quantum properties of blackholes, and it has been proposed as a fundamental principle of quantum gravity and spacetime by ‘t Hooft and Susskind. One of the remarkable progresses of string theory in the last twenty years is the realization of this principle in terms of the AdS/CFT correspondence. In this colloquium, I will talk about how developments in string theory has contributed to the understanding of this principle.
Recently an intriguing connection between quantum entanglement between microscopic degrees of freedom in a quantum theory and geometric properties of spacetime in the gravitational theory has been pointed out. This surprising perspective has leaded to new insights in the understanding of quantum information, and its relation with holography and the nature of spacetime. I will highlight some of these recent progress as well.
