Quantum theory from rules on information acquisition

In contrast to relativity, quantum theory has evaded a commonly accepted
apprehension, in part because of a long-lasting lack of physical
statements that fully characterise it. However, the past decade has seen
considerable progress in remedying this situation thanks to a wave of
derivations of quantum theory from operational postulates, aiming at
answering Wheeler's question "why the quantum?''.  In this talk, I will
review how the formalism of quantum theory (for arbitrarily many qubits)
can be reconstructed from operational rules restricting an observer’s
acquisition of information. This reconstruction offers an informational
explanation for the architecture of the theory and specifically for its
correlation structure. In particular, it explains entanglement, monogamy
and non-locality compellingly from limited accessible information and
complementarity. Time permitting, I may also discuss how, as a byproduct,
it unravels new `conserved informational charges' from complementarity
relations that characterise the unitary group and the set of pure states.
