QUARTZ (Quantum Information Access and Retrieval Theory) is an Innovative Training Network that aims to educate its Early Stage Researchers to adopt a novel theoretically and empirically motivated approach to Information Access and Retrieval based on the quantum mechanical framework that gives up the notions of unimodal features and classical ranking models disconnected from context. The present document reports on the QUARTZ Winter School, one of the activities of the QUARTZ training programme. The school was held at the Department of Information Engineering of the University of Padova, Padova, Italy, from February 7 to February 14, 2018. This report describes the goal of the school framed within the training activities of the QUARTZ project, how the school was structured in terms of lectures and activities devoted to the acquisition of transversal skills.
