The quest for a complete set of physical or information-theoretic principles that capture the essence of quantum information processing is attracting an increasing number of researchers. This new research trend aims at deriving quantum protocols and connections between them directly from basic principles, without assuming quantum theory and its mathematical dowry of Hilbert spaces and observable algebras. Particularly relevant to the process is the characterization of information-theoretic foils to quantum theory, that is, general probabilistic theories that differ from quantum theory in their information processing capabilities. Ultimately, this research is expected to provide insights in many other areas of fundamental physics and to contribute to the development of a new informational view of nature.

Thanks to the injection of fresh ideas on information processing, the field of quantum foundations is currently experiencing an exceptional growth, with a flourishing of new results and an increasing number of researchers joining the community. This conference aims to capture the excitement pervading the field and to boost its future progress, providing an overview of the main recent trends, bringing together researchers working on quantum foundations and quantum information processing, promoting the exchange of ideas and the development of collaborative work in a relaxed atmosphere. We encourage all interested researchers to take part in this exciting occasion.

The conference represents the continuation of a series of focused workshops organized in Cambridge and ETH Zurich during the past four years and is expected to have a much broader audience due to the increasing interest gained by the topic and to the enlargement of the community. In order to cover a wider spectrum of contributions, the conference will also feature a poster session where participants are encouraged to present their work.
