Symmetric measurements attaining the accessible information
Thomas Decker
A theorem of Davies states that for symmetric quantum states there exists a symmetric POVM maximizing the mutual information. To apply this theorem the representation of the symmet…

Quantum circuits for single-qubit measurements corresponding to platonic solids
Thomas Decker, Dominik Janzing, Thomas Beth
Each platonic solid defines a single-qubit positive operator valued measure (POVM) by interpreting its vertices as points on the Bloch sphere. We construct simple circuits for impl…

Measuring 4-local n-qubit observables could probabilistically solve PSPACE
Pawel Wocjan, Dominik Janzing, Thomas Decker +1
We consider a hypothetical apparatus that implements measurements for arbitrary 4-local quantum observables A on n qubits. The apparatus implements the ``measurement algorithm'' af…
