Milne A, Jevtic S, Jennings D, et al., 2014, Quantum steering ellipsoids, extremal physical states and monogamy, New Journal of Physics, Vol: 16, ISSN: 1367-2630
Any two-qubit state can be faithfully represented by a steering ellipsoid inside the Bloch sphere, but not every ellipsoid inside the Bloch sphere corresponds to a two-qubit state. We give necessary and sufficient conditions for when the geometric data describe a physical state and investigate maximal volume ellipsoids lying on the physical-unphysical boundary. We derive monogamy relations for steering that are strictly stronger than the Coffman?Kundu?Wootters (CKW) inequality for monogamy of concurrence. The CKW result is thus found to follow from the simple perspective of steering ellipsoid geometry. Remarkably, we can also use steering ellipsoids to derive non-trivial results in classical Euclidean geometry, extending Euler?s inequality for the circumradius and inradius of a triangle.

Ahmadi M, Jennings D, Rudolph T, 2013, The Wigner-Araki-Yanase theorem and the quantum resource theory of asymmetry, New Journal of Physics, Vol: 15, ISSN: 1367-2630
The Wigner–Araki–Yanase (WAY) theorem establishes an importantconstraint that conservation laws impose on quantum mechanical measurements.We formulate the WAY theorem in the broader context of resource theories,where one is constrained to a subset of quantum mechanical operations describedby a symmetry group. Establishing connections with the theory of quantumstate discrimination we obtain optimal unitaries describing the measurementof arbitrary observables, explain how prior information can permit perfectmeasurements that circumvent the WAY constraint, and provide a frameworkthat establishes a natural ordering on measurement apparatuses through adecomposition into asymmetry and charge subsystems.
