We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Error-Disturbance Tradeoff in Sequential Quantum Measurements

Abstract
We derive a state-dependent error-disturbance tradeoff based on statistical distance in the sequential measurements of a pair of noncommutative observables and experimentally verify the relation with a photonic qubit system. We anticipate that this work may further stimulate the study on the quantum uncertainty principle and related applications in quantum measurements.
