Information-Disturbance Theorem for Mutually Unbiased Observables
arXiv:quant-ph/0602057 · doi:10.1103/PhysRevA.73.042317
Abstract
We derive a novel version of information-disturbance theorems for mutually unbiased observables. We show that the information gain by Eve inevitably makes the outcomes by Bob in the conjugate basis not only erroneous but random.
