Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Error Exponents and Rényi Information Divergence in Quantum Information
量子信息 误差指数 仁义信息发散
2023/4/28
In quantum information theory, the error exponents characterize the best rate of exponential convergence of the error towards 0 or 1, as the number of copies of the underlying resources increases. In ...
Donuts,math,and superdense teleportation of quantum information
Donuts math superdense teleportation quantum information
2015/6/18
Putting a hole in the center of the donut—a mid-nineteenth-century invention—allows the deep-fried pastry to cook evenly, inside and out. As it turns out, the hole in the center of the donut also hold...
Behavior patterns of online users and the effect on information filtering
bipartite networks reshuffling process information filtering
2011/8/3
Abstract: Understanding the structure and evolution of web-based user-object bipartite networks is an important task since they play a fundamental role in online information filtering. In this paper, ...
A Characterization of Entropy in Terms of Information Loss
Shannon entropy Tsallis entropy information theory measure-preserving function
2011/7/27
Abstract: There are numerous characterizations of Shannon entropy and Tsallis entropy as measures of information obeying certain properties. Using work by Faddeev and Furuichi, we derive a very simple...
Free Fock space and functional calculus approach to the n-point information about the "Universe"
Free Fock space functional calculus the n-point information
2010/11/16
Starting from a differential equation for the unique field, the equation for the generating vector |V> of the n-point information (correlation and smeared functions) in the free Fock space is derived...

Maximum Path Information Fokker-Planck Equation
2010/11/23
We present in this paper a rigorous method to derive the nonlinear Fokker-Planck (FP) equation of anomalous diffusion directly from a generalization of the principle of least action of Maupertuis prop...
Exciton-phonon information flow in the energy transfer process of photosynthetic complexes
Exciton-phonon information flow energy transfer photosynthetic complexes
2010/11/18
Non-Markovian and non-equilibrium phonon effects are believed to be key ingredients in the energy transfer in photosynthetic complexes, especially in complexes which exhibit a regime of intermediate ...
Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator
Quantum information transfer nitrogen-vacancy centers coupled whispering-gallery microresonator
2010/11/9
We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (NV) centers coupled to a high-Q microspherical resonator. We show that, base...
Derivation of the Rules of Quantum Mechanics from Information-Theoretic Axioms
Derivation Quantum Mechanics Information-Theoretic Axioms
2010/11/8
Conventional quantum mechanics with a complex Hilbert space and the Born Rule is derived from five axioms describing properties of probability distributions for the outcome of measurements. Axioms I,...
Comparing globalness of bipartite unitary operations acting on quantum information: delocalization power, entanglement cost, and entangling power
Comparing globalness bipartite unitary operations acting quantum information delocalization power entanglement cost entangling power
2010/11/8
We compare three different characterizations of the globalness of bipartite unitary operations based on different tasks, namely, delocalization power, entanglement cost for LOCC implementation, and e...
Classical and Quantum Fisher Information in the Geometrical Formulation of Quantum Mechanics
Classical Quantum Fisher Information Geometrical Formulation Quantum Mechanics
2010/10/21
The tomographic picture of quantum mechanics has brought the description of quantum states closer to that of classical probability and statistics. On the other hand, the geometrical
formulation of qu...
The time evolution of a qubit, consisting of two single-level quantum dots, is studied in the
presence of telegraph noise. The dots are connected by two tunneling paths, with an Aharonov-
Bohm flux ...
