Information/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 ...
متن کاملOptimal Adaptive Feedback Disturbance Rejection
Discrete-time adaptive disturbance rejection has broad engineering and scientific applications. It is most relevant in active noise and vibration control. Disturbance rejection algorithms can be of two types, feed-forward or feedback. The latter generally exhibit superior performance since they take into account the effect of the feedback path from control to measurement. In this paper we propo...
متن کاملExperimental demonstration of coherent state estimation with minimal disturbance.
We investigate the optimal trade-off between information gained about an unknown coherent state and the state disturbance caused by the measurement process. We propose several optical schemes that can enable this task, and we implement one of them, a scheme that relies on only linear optics and homodyne detection. Experimentally we reach near optimal performance, limited only by detection ineff...
متن کاملFuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve
Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...
متن کاملTunable active acoustic metamaterials
We describe and demonstrate an architecture for active acoustic metamaterials whose effective material parameters can be tuned independently over a wide range of values, including negative material parameters. The approach is demonstrated experimentally through the design and measurement of two types of unit cells that generate metamaterials in which either the effective density or bulk modulus...
