Information-Disturbance Tradeoff in Quantum State Discrimination
When discriminating between two pure quantum states, there exists a quantitative tradeoff between the information retrieved by the measurement and the disturbance caused on the unknown state. We derive the optimal tradeoff and provide the corresponding quantummeasurement. Such an optimal measurement smoothly interpolates between the two limiting cases of maximal information extraction and no me...
متن کاملUncertainty trade-off and disturbance trade-off for quantum measurements
An important non-classical feature of quantum measurements is the celebrated uncertainty trade-off, namely that the uncertainties in the outcomes of measurements performed on distinct yet identically prepared ensembles of systems cannot all be made arbitrarily small. Recently, we have shown that quantum measurements also exhibit another non-classical feature of disturbance trade-off namely, tha...
متن کاملInformation-disturbance Tradeoff in Covariant Quantum State Estimation
There exists a precise tradeoff between the amount of information extracted from a quantum measurement and the amount of disturbance caused on the system, analogous to Heisenberg relations holding in the preparation procedure of a quantum state. The study of such a tradeoff is relevant for both foundation and its enormous relevance in practice, in the realm of quantum key distribution and quant...
متن کاملInformation Gain vs. State Disturbance in Quantum Theory
The engine that powers quantum cryptography is the principle that there are no physical means for gathering information about the identity of a quantum system’s state (when it is known to be prepared in one of a set of nonorthogonal states) without disturbing the system in a statistically detectable way. This situation is often mistakenly described as a consequence of the “Heisenberg uncertaint...
متن کاملInformation/disturbance trade-off in single and sequential measurements on a qudit signal
Abstract. We address the trade-off between information gain and state disturbance in measurement performed on qudit systems and devise a class of optimal measurement schemes that saturate the ultimate bound imposed by quantummechanics to estimation and transmission fidelities. The schemes are minimal, i.e. they involve a single additional probe qudit, and optimal, i.e. they provide the maximum ...
