QISS is a recently proposed consortium across several leading institutes composed of researchers in Physics, Mathematics and Computer Science, whose work and interests intersect at the interface between Quantum Computing and Quantum Gravity. The proposed consortium will meet in November 2018 (Gravity in Qubits). 

We are currently actively seeking funding for the employment of several young researchers and the organization of a series of colloquia focused on knowledge transfer and establishing dialogue between the QC and QG commmunities. 


The research objectives of QISS arise from the following three lines of questioning, which proceed from the abstract to the physical.

What is the operational interpretation of quantum gravitational phenomena? That is, how do we give a consistent mathematical description of laboratory measurements involving quantum spacetime and what are the observable physical magnitudes? Answering this question will allow to identify physical questions arising from theory that we may ask of experiment. 

How are Unitarity, Causality and Locality formulated in the absence of a fixed background spacetime? By extension, what is a quantum circuit description of theories for Quantum Gravity? 
​

What are the physical regimes that can provide access to Quantum Gravity in the near future through bench-top experiments and simulations with quantum computers? A particularly promising avenue for table top experiments is the recent discovery that interference effects arising from spacetime being in a quantum superposition would be accessible with available technology.
