On independence-friendly fixpoint logics

J. C. Bradfield
2004 Philosophia Scientiæ  
We relate it to parity games of imperfect information, and show its application to defining independence-friendly modal mu-calculi.  ...  Abstract: We introduce a fixpoint extension of Hintikka and Sandu's IF (independence-friendly) logic. We obtain some results on its complexity and expressive power.  ...  To obtain a class of decidable imperfect parity games, we will first give a parity game semantics for IF-LFP, and then define a class of imperfect parity games characterized by IF-LFP. Definition 17.  ...

BDSW protocol revisited: an efficient method for the key distillation without classical computational complexity [article]

Xiang-Bin Wang
2004 arXiv   pre-print
We also apply the method to the case of imperfect source where a small fraction of signals are tagged by Eve.  ...  Here we show that the BDSW method given by Bennett et al can be modified and the error correction and privacy amplification can be done separately with two INDEPENDENT parity matrices.  ...  Modified BDSW protocol: error correction and privacy amplification with two independent parity matrices.  ...

B. C. Hiesmayr
2015 Scientific Reports  
We find that the weak decay process corresponds to an interferometric device with a fixed visibility and fixed phase difference for each hyperon.  ...  Differently stated the weak interaction process corresponds to spin measurements with an imperfect Stern-Gerlach apparatus.  ...  Bertlmann (University of Vienna) for discussions. This work was funded by the Austrian Science Fund (FWF-P26783).  ...

Noise robustness in multilayer neural networks

M Copelli, R Eichhorn, O Kinouchi, M Biehl, R Simonetti, P Riegler, N Caticha
1997 Europhysics letters  
In this case we find a universal behaviour independent of the machine size for both the tree parity and committee machines.  ...  -The training of multilayered neural networks in the presence of different types of noise is studied. We consider the learning of realizable rules in nonoverlapping architectures.  ...  The structure of the problem in the presence of output noise permits to factor out a common kernel, independent of K and architecture, which is responsible for the fixed-point properties in the vicinity  ...

Alternating orientation and alternating colouration of perfect graphs

C.T Hoàng
1987 Journal of combinatorial theory. Series B (Print)  
We establish a property of minimal imperfect graphs, and use this property to generate two classes of perfect graphs.  ...  The second class contains all triangulated graphs and all line-graphs of bipartite graphs.  ...  In fact, Tucker [24] proved that (2.1) holds for minimal imperfect graphs; and Olaru (see Corollary 2' of Theorem 13 in [21] ) independently proved that both (2.1) and (2.2) hold for minimal imperfect  ...

The equations of state and those relations are independent of the intrinsic geometry of X and S.  ...  The perturbations with odd parity mode do not couple to gravitational waves. The perturbations of the scalar field may be expressed using only the spherical harmonics of even parity.  ... 

Channel Coding for Progressive Images in a 2-D Time-Frequency OFDM Block With Channel Estimation Errors

L. Toni, Yee Sin Chan, P.C. Cosman, L.B. Milstein
2009 IEEE Transactions on Image Processing  
In one example, for a system experiencing flat fading, low Doppler, and imperfect CSI, we find that the increase in PSNR compared to a system without time diversity is as much as 9.4 dB.  ...  Specifically, the effects of channel estimation errors, frequency selectivity and the rate of the channel variations are taken into consideration for the construction of the 2-D time-frequency block.  ...  In Fig. 4 , we show the optimized construction of RS information symbols, RS parity symbols and RCPC parity symbols for different 's for , normalized Doppler spread , dB, and both perfect CSI and imperfect  ...

A Retraction Theorem for Distributed Synthesis [article]

Dietmar Berwanger, Anup Basil Mathew, R. Ramanujam
2016 arXiv   pre-print
This is natural in games of imperfect information, rather than the common assumption that objectives are expressed in terms of events that are observable to all agents.  ...  We characterise decidable distributed synthesis problems in terms of finiteness of knowledge states and finite congruence classes induced by them.  ...  Moreover, we wish to synthesize strategies for each component acting independently, and hence we have a problem of distributed synthesis in imperfect information games, even in the restricted case of coordinating  ...

One-shot entanglement generation over long distances in noisy quantum networks

S. Perseguers, L. Jiang, N. Schuch, F. Verstraete, M. D. Lukin, J. I. Cirac, K. G. H. Vollbrecht
2008 Physical Review A. Atomic, Molecular, and Optical Physics  
Meanwhile, the overhead of local resources only increases logarithmically with the size of the network, making our proposal favorable to practical applications of long-distance quantum communication.  ...  We consider the problem of creating a long-distance entangled state between two stations of a network, where neighboring nodes are connected by noisy quantum channels.  ...  We therefore need approximately seven qubits at each station, and this number is independent of the size of the lattice.  ...

Games with Imperfect Information [chapter]

2014 Logic in Games  
Then, a new type of game unifying the concepts of concurrency and imperfect information is presented. Finally, we discuss of the extension on infinite arenas.  ...  Recently, a new type of game has been introduced: games with imperfect information. They allow the modeling of more sophisticated systems, but bring also new calculability problems.  ...  We fix two strategies for Eve and Adam.  ...

Experimental many-pairs nonlocality

Hou Shun Poh, Alessandro Cerè, Jean-Daniel Bancal, Yu Cai, Nicolas Sangouard, Valerio Scarani, Christian Kurtsiefer
2017 Physical Review A  
In presence of many entangled pairs, this violation decreases quickly with the number of pairs, and vanishes for some critical pair number that is a function of the noise present in the system.  ...  Collective measurements on large quantum systems together with a majority voting strategy can lead to a violation of the CHSH Bell inequality.  ...  Instead, we set the basis and record the number of events in a fixed time.  ...

Quantum error correction for state transfer in noisy spin chains

Alastair Kay
2016 Physical Review A  
A spin chain can be engineered such that, in the absence of imperfections and noise, an unknown quantum state is transported from one end of the chain to the other, due only to the intrinsic dynamics of  ...  Can robustness against experimental imperfections and noise be embedded into a quantum simulation? In this paper, we report on a special case in which this is possible.  ...  This has a fixed parity of excitation number provided d is even.  ...

Statistical uncertainty in quantum-optical photodetection measurements

Konrad Banaszek
1999 Journal of Modern Optics  
We show that utilization of the reconstructed distribution to evaluate a simple well-behaved observable, namely the parity operator, encounters difficulties due to accumulation of statistical errors.  ...  As the parity operator yields the Wigner function at the phase space origin, this example also demonstrates that transformation between various experimentally determined representations of the quantum  ...  phase independent observable.  ...
