Contradictions between different measures of quantum uncertainty

Alternative measures of uncertainty in quantum metrology: Contradictions and limits

We examine a family of intrinsic performance measures in terms of probability distributions that generalize Hellinger distance and Fisher information. They are applied to quantum metrology to assess the uncertainty in the detection of minute changes of physical quantities. We show that different measures lead to contradictory conclusions, including the possibility of arbitrarily small uncertain...

No contradictions between Bohmian and quantum mechanics

Two recent claims by A. Neumaier (quant-ph/0001011) and P. Ghose (quant-ph/0001024) that Bohmian mechanics is incompatible with quantum mechanics for correlations involving time are shown to be unfounded.

Relationships between uncertainty measures, fuzziness measures and divergence measures

Reply to No Contradictions between Bohmian and quantum mechanics

When these are substituted into his equation (17), the right hand side of his equation (18) vanishes. What Marchildon’s calculations have, in fact, established is that the assumption of translation invariance (Fraunhoffer diffraction and plane waves) imposed by me in my papers are sufficient but not necessary to obtain the basic result, namely that the trajectories are symmetrical at all times ...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
