Device-independent quantum information processing - Nicolas Brunner

In physics, experimental observations are usually described using theoretical models which make specific assumptions on the physical system under consideration. Device-independent quantum information investigates the converse approach. What can be said about a physical system from raw experimental data, that is, without making any assumptions about the system and the measurement device. Beyond the fundamental interest, these ideas are relevant for information processing, and may lead to the ultimate form of security in quantum cryptography.
