Quantum theory is, with general relativity, the major theoretical achievement of modern physics. It has nowadays spread into every area of science and a huge amount of research are dedicated to understand and develop technologies using the fundamental features of quantum theory. Research in quantum information, quantum communication and computation have led to many breakthrough in technological developments but also to our fundamental understanding of the physical world. And the promises, like developing a quantum computer, open up many new perspectives for progresses in technologies and science.
Space research has been and will be greatly influenced by the new developments of quantum theory. On the technological side, communication protocols, which have been transformed by the use of quantum resources, or the use of enhanced sensors using the fundamental properties of quantum systems will greatly improve the scientific potential of space missions. Moreover, the new possibilities offered by quantum computation and simulation will enable new technological developments like the manufacturing of materials with specific physical properties from first principles. This will naturally have consequences on the way space missions are designed. From a science perspective, space remains a vast laboratory to test quantum theory on scales which are not accessible on Earth-based experiments. For instance, space is the perfect laboratory to test the interplay between gravity and quantum theory, from the simple experiments testing the coherence properties of massive objects (QPPF CDF Study) to observing large astrophysical events where gravity and quantum theory should both play a fundamental role (early universe and black hole physics).
This conference purpose is to present in a synthetic way the progresses made in the fields of quantum information,quantum computation and quantum foundations and to put them in perspective for future space applications.
