Quantum Gravity in the Lab. I. Teleportation by Size and Traversable Wormholes [PDF]
PRX Quantum, 2019 With the long-term goal of studying quantum gravity in the lab, we propose holographic teleportation protocols that can be readily executed in table-top experiments.

Theory of Quantum Gravity Information Processing [PDF]
Quantum Eng. 1, 4:e23 (2019), 2014 The theory of quantum gravity is aimed to fuse general relativity with quantum theory into a more fundamental framework. The space of quantum gravity provides both the non-fixed causality of general relativity and the quantum uncertainty of quantum mechanics.

The causal set approach to quantum gravity [PDF]
Living Reviews in Relativity, 2019 The causal set theory (CST) approach to quantum gravity postulates that at the most fundamental level, spacetime is discrete, with the spacetime continuum replaced by locally finite posets or “causal sets”.

A DIALOG ON QUANTUM GRAVITY [PDF]
International Journal of Modern Physics D, 2003 The debate between loop quantum gravity and string theory is sometime lively, and it is hard to present an impartial view on the issue. Leaving any attempt to impartiality aside, I report here, instead, a conversation on this issue, overheard in the cafeteria of a Major American University.

Contextual extensions of quantum gravity models [PDF]
International Journal of Geometric Methods in Modern Physics Vol.
18, No. 6 (2021) 2150085, 2020 We present a simple way of incorporating the structure of contextual extensions into quantum gravity models. The contextual extensions of $C^*$-algebras, originally proposed for contextual hidden variables, are generalized to the cones indexed by the contexts and their limit in a category. By abstracting the quantum gravity models as functors, we study

The quantum gravity dynamics of near extremal black holes [PDF]
Journal of High Energy Physics, 2018 We study the quantum effects of Near-Extremal black holes near their horizons. The gravitational dynamics in such backgrounds are closely connected to a particle in AdS2 with constant electric field. We use this picture to solve the theory exactly.

Sphere packing and quantum gravity [PDF]
Journal of High Energy Physics, 2019 We establish a precise relation between the modular bootstrap, used to con- strain the spectrum of 2D CFTs, and the sphere packing problem in Euclidean geometry.

Modified gravity from the quantum part of the metric [PDF]
Eur. Phys. J. C (2014) 74:2743, 2013 It is shown that if a metric in quantum gravity can be decomposed as a sum of classical and quantum parts then Einstein quantum gravity looks approximately like modified gravity with a nonminimal interaction between gravity and matter.
