Raphael Bousso (

UC Berkeley. He is known for the Bousso bound on the information content of the universe.[1][2][3] With Joseph Polchinski, Bousso proposed the string theory landscape as a solution to the cosmological constant problem.[4][5]

Life and career

Bousso was born in

University of California, Berkeley. In 2012, Bousso was elected Fellow of the American Physical Society "for fundamental discoveries in the field of quantum cosmology, including the covariant entropy bound and the string landscape."[7]

Research

Bousso's research is focused on quantum gravity and cosmology, particularly through the study of quantum information.[8] His 1999 covariant entropy bound[1] (Bousso bound) established a general relation between quantum information and the geometry of spacetime (i.e., gravity).[9] The Bousso bound has since been refined and strengthened, leading to provable new results in quantum field theory, such as the quantum null energy condition.[10][11][12][13] Bousso has also worked on the black hole information paradox (firewall problem).[14] Since 2018, he has led a consortium of theoretical and experimental physicists exploring and developing the relations between quantum gravity, quantum information, and quantum computing.[15][16]

In 2000, Bousso and

vacua, including solutions compatible with the observed positive value of the cosmological constant (vacuum energy).[4] This came to be called the "landscape of string theory."[17][5] Bousso has developed an approach to the cosmological measure problem,[18] with the ultimate goal of testing the string theory landscape.[19]
