The Quantum Jump Approach and Quantum Trajectories
A both conceptually and practically useful tool for the description of modern experiments on a single atom or a single system is the quantum jump approach with the associated quantum trajectories. The underlying ideas are outlined and then extended to moving systems. A new application to the problem of quantum arrival times is indicated.
متن کاملQuantum beats revisited: A quantum jump approach
The term quantum beats refers to a superposed oscillatory behavior in the light intensity emitted by some suddenly excited atomic systems in their subsequent decay. In this paper we reinvestigate quantum beats for systems where two upper levels may decay to a common ground state by using the recently developed approach of quantum jumps. The treatment turns out to be very simple and intuitive. I...
متن کاملQSES’s and the Quantum Jump
The stochastic methods in Hilbert space have been used both from a fundamental and a practical point of view. The result reported here concerns the application of these methods to model the evolu tion of quantum systems and does not enter into the question of their fundamental or practical status. It can easily be stated as follows: Once a quantum stochastic evolution scheme is assumed, the in...
متن کاملThermodynamics of quantum jump trajectories.
We apply the large-deviation method to study trajectories in dissipative quantum systems. We show that in the long time limit the statistics of quantum jumps can be understood from thermodynamic arguments in terms of dynamical phases and transitions between them in trajectory space. We illustrate our approach with three simple examples: a driven 2-level system where we find a particular scale i...
متن کاملQuantum Dots: A Quantum Jump for Molecular Imaging?
Visual analysis of biomolecules is a fundamental subject of basic and applied biologic research. In such fields as genetics, biochemistry, and molecular biology, visible fluorescent protein constructs provide researchers with a tool of enormous value that has facilitated the identification of key molecules involved in cellular function in tissue sections and in living cells. Recently, the succe...
