Talk Title: What is Discrete Covariance?

Talk Abstract:
Covariance is the mother of all Physics symmetries. Whilst its meaning in the continuum is clear enough, it does lack a consensual discrete counterpart. I will give my understanding of different meanings attached to "Discrete Covariance".

About QISS

The Quantum Information Structure of Spacetime (http://www.qiss.fr) is an interdisciplinary research initiative among several universities and research institutes all over the world, supported by the John Templeton Foundation through the following grant:

https://www.templeton.org/grant/the-q...

The goal of QISS is to explore and connect the research domains of Quantum Information/Computing, Quantum Gravity and Quantum Foundations. Main objectives are to found the physics of quantum spacetime on an information-theoretic basis, to bring within reach empirical access to quantum gravity in 'table-top' laboratory conditions by exploiting rapid advances in quantum computing related technologies and using quantum information theoretic concepts, and to promote an extensive interaction between physicists and philosophers on the conceptual role of information in spacetime physics.
