Extended mutually unbiased bases to arbitrary-rank measurements with new structural relations. Proved incompatibility robustness equals λ₃,ₙ/3 for all 3-UMs. Hadamard-Clifford construction yields first non-binary examples.

Researchers establish definitive bounds on magic resources needed for enhancing classically simulable measurements, proving quantum catalysts and memories offer no improvement for discriminating states with positive Wigner functions.

We derive exact conditions for when quantum channels render all measurements jointly measurable on qubits, proving PVM and POVM incompatibility-breaking equivalence for unital channels and establishing steering criteria for two-qubit states.
