About Us


QISS is a fundamental research initiative across disciplines, in the broader fields of Quantum Information and Quantum Gravity. We aim to found the physics of quantum spacetime on an information theoretical basis, bring within reach empirical access to quantum gravity phenomenology using technologies that quantum manipulate gravitating mesoscopic masses, and promote an extensive interaction between physicists and philosophers. The conceptual premise of QISS is to deepen the current understanding of this slippery but crucial notion that is rapidly taking a central role in our understanding of the structure of reality: Information.

The broader scope of the collaboration is to establish a long term research program that brings together the communities represented towards the common goal of unravelling the Quantum Information Structure of Gravity. We aim to provide a forum for researchers interested at the interface of Quantum Information and Quantum Gravity. We work to catalyse a fertile dialogue and demonstrate the benefits of cross fertilisation of ideas. Our end goal is to make contact with experiments and advance our fundamental understanding of reality.

QISS was initially conceived from interactions between the Quantum Gravity Group of the Center for Theoretical Physics and the Laboratory of Informatics and Systems at the University of Aix-Marseille, France. It was concretely conceived as a multinational initiative during a preliminary meeting at the Slovak Academy of Sciences in November 2018, and took off by a generous three year grant by the John Templeton Foundation awarded to the Center for Space, Time and the Quantum that coordinates the project. Numerous post-doctoral fellowships, PhD scholarships, a series of colloquiums, and scientific visits are supported by QISS.

To what extend is Reality objectively determined independently of the Information that it is possible to have about it?

Are space and time losing their role as grounds for an objective physical reality?

What does it mean for an observer or "agent" to exist in a superposition of spacetimes? What does he experience?

Can we detect spacetime in a quantum superposition in the lab?

Can correlations between sources and detectors for locally defined quantum fields be specified purely in terms of a relational notion of space and time?

Can physical laws be expressed in terms of Information processing?


In spite of the explosion of interest for the role played by the notion of Information in the foundations of quantum theory and spacetime physics, we are far from having a shared and clear understanding of what we mean by Information. Different research groups use this notion in the context of different perspectives. The QISS project brings together an outstanding and coherent consortium of researchers in Quantum Gravity, Quantum Information and the Philosophy of Physics, with the aim of creating synergy capable of addressing foundational questions and introduce quantum information as the fundamental concept on which to base quantum gravitational physics. A dialogue and a common theoretical framework for Quantum Information and Quantum Gravity may foster a major breakthrough in our understanding of what we call space and time.
