Wigner–Araki–Yanase theorem
text:
The Wigner–Araki–Yanase theorem, also known as the WAY theorem, is a result in quantum physics establishing that the presence of a conservation law limits the accuracy with which observables that fail to commute with the conserved quantity can be measured. It is named for the physicists Eugene Wigner, Huzihiro Araki and Mutsuo Yanase. The theorem can be illustrated with a particle coupled to a measuring apparatus. If the position operator of the particle is q and its momentum operator is p , and
