Quantum transport in mesoscopic systems and the measurement problem

S. A. Gurvitz

Published Mar 6, 1996• 0 citations
arXivHTMLPDF

Abstract

We study noninvasive measurement of stationary currents in mesoscopic systems. It is shown that the measurement process is fully described by the Schrödinger equation without any additional reduction postulate and without the introduction of an observer. Nevertheless the possibility of observing a particular state out of coherent superposition leads to collapse of the wave function, even though the measured system is not distorted by interaction with the detector. Experimental consequences are discussed.

Interaction-Free Measurement in mesoscopic systems and the reduction postulate

S. A. Gurvitz

We show that a noninvasive,``negative-result measurement'' can be realized in quantum dot systems. The measurement process is studied by applying the Schrödinger equation to the whole system (including the detector). We demonstrate that the possibility of observing a particular state out of coherent superposition leads to collapse of the corresponding nondiagonal density-matrix elements of the measured system. No additional reduction postulate is needed. Experimental consequences of the collapse time and the relativistic requirement are discussed for mesoscopic and optical systems.

On Collapse of Quantum State on Measurement

Basudev Nag Chowdhury, Sanatan Chattopadhyay

Abstract In the context of the century-long debate on quantum measurement problem, the current work proposes a model that describes the process of collapse of state by quantum interaction, which resolves the controversies of the framework of quantum mechanics and describes the entire domain of quantum-to-classical world including the weak measurement and partial collapse. ‘Measurement’, being the process of physically interacting with a system in order to extracting information from it, is theorized in the current model by synthesizing the quantum interaction between system and measuring apparatus with the information entropy of such process. The model assumes Schrödinger equation to be the only guiding equation for all physical systems including the measuring apparatus, and does not presuppose ‘superposition principle’, rather derives it theoretically from the formulation. The superposed state is shown to be independent of the choice of measurement operator (observable) or basis states (pointers) of the measuring apparatus. Most interestingly, the current model explains the non-observance of ‘superposition principle’ by classical systems as the classical limit of such quantum description of measurement. Along with solving the quantum measurement problem, the work also explains weak measurement and partial collapse, which can be further extended to investigate such several emerging critical phenomena.

Measurements with a noninvasive detector and dephasing mechanism

S. A. Gurvitz

We study the dynamics of the measurement process in quantum-dot systems, where a particular state out of coherent superposition is observed. The ballistic point contact placed near one of the dots is taken as a noninvasive detector. We demonstrate that the measurement process is fully described by the Bloch-type equations applied to the whole system. These equations clearly reproduce the collapse of the density matrix into the statistical mixture in the course of the measurement process. The corresponding dephasing width is uniquely defined. We show that the continuous observation of one of the states in a coherent superposition may accelerate decay from this state---in contradiction with rapidly repeated observations, which slow down the transitions between quantum states (the quantum Zeno effect).

Bohmian formulation of Full Counting Statistics in mesoscopic systems

Guillermo Albareda, Fabio L. Traversa, Xavier Oriols

Predicting time-dependent current correlations in mesoscopic systems represents a challenge to theorists because it requires the ability to reproduce sequential measurements, i.e. unitary (Schrödinger-like) and non-unitary (collapse-like) evolutions of the quantum systems. On the contrary, Bohmian formulation of quantum theory, in terms of quantum trajectories guided by waves, by construction, exactly reproduces all quantum phenomena (even correlations) without needing to invoke the role of the operators in the system's measurement. Here, by simply highlighting the operatorless character of Bohmian mechanics, we show that the conceptual difficulties associated to sequential measurements, when electron transport is formulated within the orthodox quantum mechanics, can be substituted by a practical difficulty in the reduction of the degrees of freedom associated to open mesoscopic systems, when the problem is formulated within Bohmian mechanics.

A model for the solution of the quantum measurement problem

Biswaranjan Dikshit

The basic idea of quantum mechanics is that the property of any system can be in a state of superposition of various possibilities (or eigen states).This state of superposition is also known as wave function and it evolves linearly with time in a deterministic way in accordance with the Schrodinger equation.However, when a measurement is carried out on the system to determine the value of that property (say position), the system instantaneously transforms to one of the eigen states and thus we get only a single value as an outcome of the measurement.Quantum measurement problem seeks to find the cause and exact mechanism governing this transformation.In an attempt to solve the above problem, in this paper, we will first define what the wave function represents in real-world and will identify the root cause behind the stochastic nature of events.Then, we will develop a model to explain the mechanism of collapse of the quantum mechanical wave function in response to a measurement.In the process of development of model, we will explain Schrodinger cat paradox and will show how Born's rule for probability becomes a natural consequence of the measurement process.
