Titre | Quantum theory from rules on information acquisition |
Résumé | In contrast to relativity, quantum theory has evaded a commonly accepted
apprehension, in part because of the lack of physical statements
that fully characterize it. In an attempt to remedy the situation, we
summarize a novel reconstruction of the explicit formalism of quantum
theory (for arbitrarily many qubits) from elementary rules on an
observer’s
information acquisition. Our approach is purely operational:
we consider an observer O interrogating a system S with binary questions
and define S’s state as O’s “catalogue of knowledge” about S;
no ontic assumptions are necessary. From the rules, one can derive,
among other things, the state spaces, the unitary group, the von Neumann
evolution and show that the binary questions correspond to Pauli
operators. The reconstruction also offers new structural insights in the
form of novel informational charges and informational complementarity
relations which define the state spaces and the unitary group. This
reconstruction permits a new perspective on quantum theory. |
