Research Interests

Professor Harlow works on combining quantum mechanics and gravity, focusing on the quantum-mechanical aspects of black holes and cosmology. Recently he has been using methods from quantum information theory to approach these problems, in particular relating the AdS/CFT correspondence—our best theory of quantum gravity so far—to the theory of quantum error correcting codes. He also works on the general structure of quantum field theory, which despite its venerable age has resisted a fully satisfactory formulation, as well as aspects of classical gravity.

Biographical Sketch

Daniel Harlow was born in Cincinnati, and grew up in Boston and Chicago. He obtained a BA in physics and mathematics from Columbia University in 2006, a PhD in physics from Stanford University in 2012, and was a postdoctoral fellow at Princeton and Harvard before joining MIT in July 2017. He is an avid hiker and pianist.
