We are looking for a PhD student to join the quantum information science group of Animesh Datta at the University of Warwick. The goal of this theoretical project will be to develop schemes for quantum-enhanced sensing of novel physics such as potential quantum fluctuations in space-time, collapse of massive quantum superpositions, and the quantum aspects of gravity more generally. Emphasis is to be placed on the experimental feasibility of these schemes in optical, mechanical, optomechanical or other platforms.
