Professor Tadashi Takayanagi
(Yukawa Institute for Theoretical Physics, Kyoto University)
👨🏫Brief Bio
Tadashi Takayanagi is currently Professor at the Yukawa Institute for Theoretical Physics, Kyoto University. He earned his Doctor of Science in Physics from the University of Tokyo in 2002, followed by postdoctoral fellowships at Harvard University from 2002 to 2005 and at the Kavli Institute for Theoretical Physics from 2005 to 2006. His work has made major contributions to several areas of theoretical physics, particularly string theory, quantum field theory, quantum gravity, and quantum entanglement. Among his many honors are the New Horizons in Physics Prize in 2015, the Nishina Memorial Prize in 2016, and the ICTP Dirac Medal in 2024.

📝 Abstract
Recently, a new interpretation of gravitational spacetime in terms of quantum entanglement has been developed. The idea of holography in string theory provides a simple geometric computation of entanglement entropy. This generalizes the well-known Bekenstein-Hawking formula of black hole entropy and strongly suggests that a gravitational spacetime consists of many qubits with quantum entanglement. Also a new progress on black hole information problem has been made recently by applying this idea. A new insight on holography for de Sitter spaces have also been obtained from quantum information viewpoints. I will explain these developments in this lecture.
