    [2206.06762] Quantum Gravity in 30 Questions

    Quantum gravity is the missing piece in our understanding of the fundamental
    interactions today. Given recent observational breakthroughs in gravity,
    providing a quantum theory for what lies beyond general relativity is more
    urgent than ever. However, the complex history of quantum gravity and the
    multitude of available approaches can make it difficult to get a grasp of the
    topic and its main challenges and opportunities. We provide a guided tour of
    quantum gravity in the form of 30 questions, aimed at a mixed audience of
    learners and practitioners. The issues covered range from basic motivational
    and background material to a critical assessment of the status quo and future
    of the subject. The emphasis is on structural issues and our current
    understanding of quantum gravity as a quantum field theory of dynamical
    geometry beyond perturbation theory. We highlight the identification of quantum
    observables and the development of effective numerical tools as critical to
    future progress.

    [1205.2019] The Spin Foam Approach to Quantum Gravity

    This article reviews the present status of the spin foam approach to the
    quantization of gravity. Special attention is payed to the pedagogical
    presentation of the recently introduced new models for four dimensional quantum
    gravity. The models are motivated by a suitable implementation of the path
    integral quantization of the Plebanski formulation of gravity on a simplicial
    regularization. The article also includes a self-contained treatment of the 2+1
    gravity. The simple nature of the latter provides the basis and a perspective
    for the analysis of both conceptual and technical issues that remain open in
    four dimensions.

    [2302.07897] Comment on "Traversable wormhole dynamics on a quantum processor"

    A recent article [Nature 612, 51-55 (2022)] claims to observe traversable
    wormhole dynamics in an experiment. This claim is based upon performing a
    teleportation protocol using a Hamiltonian that...
