Abstract: We summarise a recent reconstruction of the quantum theory of qubits from rules constraining an observer’s acquisition of information. This review of [arXiv:1412.8323, arXiv:1511.01130] is accessible and fairly self-contained, focussing on the main ideas and results and not the technical details. The reconstruction offers an informational explanation for the architecture of the theory and specifically for its correlation structure. In particular, it illuminates the origin of entanglement and monogamy. As a by-product, it also unravels new `conserved informational charges’ from complementarity relations that characterise the unitary group and the set of pure states.
