On Gravity's Role in Quantum State Reduction
The stability of a quantum superposition of two different stationary mass distributions is examined, where the perturbing effect of each distribution on the space-time structure is taken into account, in accordance with the principles of general relativity. It is argued that the definition of the time-translation operator for the superposed space-times involves an inherent ill-definedness, lead...
متن کاملMartingale Models for Quantum State Reduction
Stochastic models for quantum state reduction give rise to statistical laws that are in most respects in agreement with those of quantum measurement theory. Here we examine the correspondence of the two theories in detail, making a systematic use of the methods of martingale theory. An analysis is carried out to determine the magnitude of the fluctuations experienced by the expectation of the o...

آموزش زبان دوم طی سالهای اخیر بدنبال روشهای بهتری برای تحقق بخشیدن به اهداف معلمین و دانش آموزان بوده است . در مورد معلمین این امر منجر به تحقیقاتی در مورد ساختار زبانی، محاوره ای و تعاملی گردیده است . در مورد دانش آموزان این امر به مطالعاتی درباره نگرش دانش آموزان نسبت به فراگیری در داخل کلاس و بیرون از آن و همچنین انواع مختلف روشهای پردازش ذهنی منجر شده است . هدف از این تحقیق یافتن روشهائی اس...
15 صفحه اولQuantum State Reduction: An Operational Approach
A rigorous theory of quantum state reduction, the state change of the measured system caused by a measurement conditional upon the outcome of measurement, is developed fully within quantum mechanics without leading to the vicious circle relative to the von Neumann chain. For the basis of the theory, the local measurement theorem provides the joint probability distribution for the outcomes of lo...
متن کاملAn Operational Approach to Quantum State Reduction
An operational approach to quantum state reduction, the state change of the measured system caused by a measurement of an observable conditional upon the outcome of measurement, is founded without assuming the projection postulate in any stages of the measuring process. Whereas the conventional formula assumes that the probe measurement satisfies the projection postulate, a new formula for dete...
