Texture Analysis And Characterization Using Probability Fractal Descriptors
Pattern Recognition Fractal Dimension Fractal Descriptors
2012/5/31
A gray-level image texture descriptors based on fractal dimension estimation is proposed in this work. The proposed method estimates the fractal dimension using probability (Voss) method. The descript...
On the probability of quantum phase slips in superconducting nanowires
quantum phase slips superconducting nanowires
2012/2/27
The paper discusses mechanisms for decay of supercurrents in ultrathin superconducting wires driven by quantum fluctuations. We argue that momentum conservation strongly suppresses probability of such...
Probability measure generated by the superfidelity

The interpretation of quantum mechanics and of probability: Identical role of the 'observer'
quantum mechanics probability
2011/9/14
The aim of the article is to argue that the interpretations of quantum mechanics and of probability are much closer than usually thought. Indeed, a detailed analysis of the concept of probability (wit...
Transition Probability (Fidelity) and Its Relatives
Transition Probability Its Relatives Quantum Physics
2011/7/27
Abstract: Transition Probability (fidelity) for pairs of density operators can be defined as "functor" in the hierarchy of "all" quantum systems and also within any quantum system. The introduction of...
A simple protocol for the probability weights of the simulated tempering algorithm: applications to first-order phase transitions
simulated tempering first-order phase transitions eigenvalues of the transfer matrix Ising and lattice-gas models
2010/11/19
The simulated tempering (ST) is an important method to deal with systems whose phase spaces are hard to sample ergodically. However, it uses accepting probabilities weights which often demand involvin...

A distribution of electromagnetic fields presents a statistical assembly of a particular type, which is at scale h a quantum statistical assembly itself and has also been instrumental to concretisati...
Continuous monitoring can improve single-photon probability
Continuous monitoring single-photon probability
2010/11/9
An engineering technique using continuous quantum measurement together with a change detection algorithm is proposed to improve the probability of single photon emission for a quantum-dot based single...
Quasi-probability representations of quantum theory with applications to quantum information science
Quasi-probability representations quantum theory applications quantum information science
2010/11/5
This article comprises a review of both the quasi-probability representations of infinite-dimensional quantum theory (including the Wigner function) and the more recently defined quasi-probability rep...
Mimicking the probability distribution of a two-dimensional Grover walk with a single-qubit coin
Mimicking the probability distribution two-dimensional Grover walk single-qubit coin
2010/11/5
Multi-dimensional quantum walks usually require large coin spaces. Here we show that the non-localized case of the spatial density probability of the two-dimensional Grover walk can be obtained using ...
The Emergence and Interpretation of Probability in Bohmian Mechanics

2011/9/7
A persistent question about the deBroglie–Bohm interpretation of quantum mechanics concerns the understanding of Born’s rule in the theory. Where do the quantum mechanical probabilities come from? How...
Error probability analysis in quantum tomography: a tool for evaluating experiments
Error probability analysis quantum tomography: evaluating experiments
2010/10/19
We expand the scope of the statistical notion of error probability, i.e., how often large deviations are observed in an experiment, in order to make it directly applicable to quantum tomography. We ve...
Kolmogorov's aporia and solution by construction of a relativized and quantified concept of factual probability
Kolmogorov's aporia solution concept of factual probability
2010/4/8
The crucial but very confidential fact is brought into evidence that, as Kolmogorov himself repeatedly claimed, the mathematical theory of probabilities cannot be applied to physical, factual probabil...
Does Security Transaction Volume-Price Behavior Resemble a Probability Wave?
Price volatility Volume kurtosis Volume-price behavior Coherence Probability wave
2010/4/27
Motivated by how transaction amount constrain trading volume and price volatility in stock market, we, in this paper, study the relation between volume and price if amount of transaction is given. We ...
