The first It From Qubit collaboration workshop and summer school was held at the Perimeter Institute in Waterloo, Canada in July, 2016. The workshop and school was attended by 180 researchers from around the world, and was, by all measures, a great succes. more
Once upon a time, about 13.8 billion years ago, our universe sprang from a quantum speck, ballooning to one million trillion trillion trillion trillion trillion trillion times its initial volume (by some estimates) in less than a billionth of a trillionth of a trillionth of a second. It then... more
Two dimensional conformal field theories (CFTs) have a very powerful property called modular invariance, which relates the high and low temperature limits of the theory. This can give nontrivial relations between the low-energy spectrum of the theory and the high-energy spectrum. By making very... more

Quantum gravity in anti de Sitter space in three spacetime dimensions is conjectured to be dual to two dimensional conformal field theories (CFTs) with sparse spectra. In this paper, we study "pure" quantum gravity in three dimensions, which is in some sense the simplest place to study quantum... more
