    [Auszug] The momentum range of the £* in the HYBUC sample (200-650 MeV/c) is particularly suited to the study of the effects of acceleration on lifetime, because the proper time for decay in the sigma rest frame is a significant fraction of the stopping time as measured in the laboratory. The mean ...

    [Auszug] Entanglement is recognized as a key resource for quantum computation and quantum cryptography. For quantum metrology, the use of entangled states has been discussed and demonstrated as a means of improving the signal-to-noise ratio. In addition, entangled states have been used in experiments ...

    [Auszug] The generation, manipulation and fundamental understanding of entanglement lies at the very heart of quantum mechanics. Entangled particles are non-interacting but are described by a common wavefunction; consequently, individual particles are not independent of each other and their quantum ...

    Notes:
    [Auszug] Teleportation of a quantum state encompasses the complete transfer of information from one particle to another. The complete specification of the quantum state of a system generally requires an infinite amount of information, even for simple two-level systems (qubits). Moreover, the principles ...

    Abstract We present a path-following algorithm for the linear programming problem with a surprisingly simple and elegant proof of its polynomial behaviour. This is done both for the problem in standard form and for its dual problem. We also discuss some implementation strategies.

    Abstract. We demonstrate that if A 1,...,A m are symmetric positive semidefinite n×n matrices with positive definite sum and A is an arbitrary symmetric n×n matrix, then the relative accuracy, in terms of the optimal value, of the semidefinite relaxation $$\max_X\{\Tr(AX)\mid\, \Tr(A_iX)\le1,\,\,i=1,...,m;\,X\succeq0\} \eqno{\hbox{(SDP)}}$$ of the optimization program $$x^TAx\to\max\mid\, x^TA_ix\le 1,\,\,i=1,...,m \eqno{\hbox{(P)}}$$ is not worse than $$1-\frac{1}{{2\ln(2m^2)}}$$ . It is shown that this bound is sharp in order, as far as the dependence on m is concerned, and that a~feasible solution x to (P) with $$x^TAx\ge \frac{{\Opt(\hbox{{\rm SDP}})}}{{2\ln(2m^2)}} \eqno{(*)}$$ can be found efficiently. This somehow improves one of the results of Nesterov [4] where bound similar to (*) is established for the case when all Ai are of rank 1.

    Abstract We present data on $$\bar pn$$ and π− n collisions obtained from an exposure of the 30′' FNAL deuterium filled bubble chamber to a mixed $${{\bar p} \mathord{\left/ {\vphantom {{\bar p} {\pi ^ - }}} \right. \kern-\nulldelimiterspace} {\pi ^ - }}$$ beam with a momentum of 100 GeV/c. We find that in 17±2% of the collisions with the antiproton there is an interaction on the spectator while for the collisions with π− mesons the corresponding number is 15±2%. The $$\bar pn$$ and π− n multiplicity distributions have average charged multiplicities of 6.46±0.07 and 6.53±0.08 respectively. The average multiplicities for both types of interactions are slightly smaller than those for the corresponding reactions on hydrogen by an amount that is the same as observed at other energies. As an estimate of $$\bar pn$$ annihilation we have calculated the difference $$\sigma _n (\bar pn) - \sigma _n (pn)$$ for each prong numbern. We find an average multiplicity of 9±1, a value close to that for $$\bar pp$$ annihilation at the same energy. combining our data with lower energy $$\bar pn$$ annihilation data, we observe that the average negative multiplicity is systematically larger than that for $$\bar pp$$ annihilation similar to the difference between neutron and proton target data with other beam projectiles.

    Notes:
    Abstract Long step interior-point methods in linear programming are some of the most efficientalgorithms from a computational point of view. We prove polynomial complexity of a classof long step target-following methods in a novel way, by introducing a new nonconvexpotential function and adapting the analysis framework of Jansen et al. [4, 6, 7]. The mainadvantage is that the new potential function has an obvious extension to semi-definiteprogramming, whereas the potential used in the above-mentioned papers does not.

    Notes:
    Abstract In this paper, we propose a method for linear programming with the property that, starting from an initial non-central point, it generates iterates that simultaneously get closer to optimality and closer to centrality. The iterates follow paths that in the limit are tangential to the central path. Together with the convergence analysis, we provide a general framework which enables us to analyze various primal-dual algorithms in the literature in a short and uniform way.
