Limit for Measurement of Length and Quantum Theory

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...

The Problem of Quantum Measurement Quantum Measurement as Thermodynamic Limit

We derive the probabilities of measurement results from Schroedinger’s equation plus a definition of macroscopic as a particular kind of thermodynamic limit. Bohr’s insight that a measurement apparatus must be classical in nature and classically describable is made precise in a mathematical sense analogous to the procedures of classical statistical mechanics and the study of Hamiltonian heat ba...

Accuracy of an Intraoral Digital System for File Length Measurement

Introdouction: Canal length measurement is essential for proper endodontic treatment. Any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. Digital radiography has enabled accurate measurement of curved canal length. In this study, we evaluated the accuracy of calibration of a complementary m...

Quantum Trajectories and Quantum Measurement Theory

Beyond their use as numerical tools, quantum trajectories can be ascribed a degree of reality in terms of quantum measurement theory. In fact, they arise naturally from considering continuous observation of a damped quantum system. A particularly useful form of quantum trajectories is as linear (but non-unitary) stochastic Schrödinger equations. In the limit where a strong local oscillator is u...
