Quantum Limits of Measurement and Computing Induced by Conservation Laws and Uncertainty Relations
arXiv:quant-ph/0210046
Abstract
A quantitative extension of the Wigner-Araki-Yanase theorem is obtained on the limitation on precise, non-disturbing measurements of observables which do not commute with additive conserved quantities, and applied to obtaining a limitation on the accuracy of quantum computing with computational bases which do not commute with angular momentum.
