Information gain in quantum continual measurements
Inspired by works on information transmission through quantum channels, we propose the use of a couple of mutual entropies to quantify the efficiency of continual measurement schemes in extracting information on the measured quantum system. Properties of these measures of information are studied and bounds on them are derived. 1 Quantum measurements and entropies We speak of quantum continual m...
متن کاملEntropy and information gain in quantum continual measurements
The theory of measurements continuous in time in quantum mechanics (quantum continual measurements) has been formulated by using the notions of instrument, positive operator valued (POV) measure, etc. [1, 2], by using quantum stochastic differential equations [3, 4] and by using classical stochastic differential equations (SDE’s) for vectors in Hilbert spaces or for trace-class operators [5, 6,...
متن کاملWeak Value and Weak Measurements
The weak value of a variable O is a description of an effective interaction with that variable in the limit of weak coupling. For a pre-and post-selected system described at time t by the two-state vector Φ| |Ψ (see entry Two-State Vector Formalism), the weak value is [1]: O w ≡ Φ|O|Ψ Φ|Ψ. (1) Contrary to classical physics, variables in quantum mechanics might not have definite values at a give...
متن کاملLimits to the information gain from lidar measurements.
Measurements over the return signal are an integral part of lidar remote sensing by which we gather information about the characteristics of specific targets. But how much information is gained by performing a given lidar measurement? By defining Shannon's mutual information of a lidar observation, here we consider the bits of information content on the measurement and describe mathematically t...
متن کاملQuantum Cognition, Neural Oscillators, and Negative Probabilities
This review paper has three main goals. First, to discuss a contextual neurophysiologically plausible model of neural oscillators that reproduces some of the features of quantum cognition. Second, to show that such model predicts contextual situations where quantum cognition is inadequate. Third, to present an extended probability theory that that not only can describe situations that are beyon...
