In multi-copy state discrimination, qubit strategies beat bit strategies, but some bit-like operational theories outperform qubits even classically, revealing nonlocality without entanglement and providing general bounds.
Extends Fano bounds to sufficiency of low conditional entropy and defines a quantum entanglement task for infinite-dimensional systems with bounds via maximal singlet fraction of finite-dimensional approximations.
