The Wigner–Araki–Yanase theorem and the quantum resource theory of asymmetry
The Wigner–Araki–Yanase theorem and the quantum resource theory of asymmetry
The Wigner–Araki–Yanase (WAY) theorem establishes an important constraint 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 described by a symmetry group. Establishing connections with the theory of …
