Title: How many ebits can be unlocked with one classical bit?


We find an upper bound on the rate at which entanglement can be unlocked by classical bits. In particular, we show that, for quantum information sources that are specified by ensembles of pure bipartite states, one classical bit can unlock at most one ebit.

  • The MB-pol many-body potential has recently emerged as an accurate molecular model for water simulations from the gas to the condensed phase. Here, the accuracy of MB-pol is systematically assessed across the three phases of water through extensive comparisons with experimental data and high-level ab initio calculations. Individual many-body contributions to the interaction energies as well as vibrational spectra of water clusters calculated with MB-pol are in excellent agreement with reference data obtained at the coupled cluster level. We investigate several structural, thermodynamic, and dynamical properties of the liquid phase at atmospheric pressure through classical molecular dynamics simulations as amore » function of temperature. Furthermore, the structural properties of the liquid phase are in nearly quantitative agreement with X-ray diffraction data available over the temperature range from 268 to 368 K. The analysis of other thermodynamic and dynamical quantities emphasizes the importance of explicitly including nuclear quantum effects in the simulations, especially at low temperature, for a physically correct description of the properties of liquid water. Furthermore, both densities and lattice energies of several ice phases are also correctly reproduced by MB-pol. Following a recent study of DFT models for water, a score is assigned to each computed property, which demonstrates the high and, in many respects, unprecedented accuracy of MB-pol in representing all three phases of water.« less
  • Let script-A/sub k/(n) be the set of n-term nonnegative integer sequences that contain no k-term arithmetic progression (AP) as a subsequence. Denote by f(A) the number of 3-term APs in the sequence A. Define f/sub k/(n) = max f(A) for A an element of script-A/sub k/(n) and s/sub k/ = lim/sub n..-->..infinity/ log f/sub k/(n)/log n. It is shown that f/sub 4/(n) greater than or equal to n/sup 1.623/ infinitely often and that s/sub k/ ..-->.. 2 as k ..-->.. infinity. The question of determining lim/sub n..-->..infinity/f/sub 4/(n) and, more generally, of determining s/sub k/ is addressed. (RWR)
  • The sensitivity of the sex-linked recessive lethal test is due to the fact that a very large number of loci are included in the mutation study. From extensive studies on the spontaneous sex-linked recessive lethal frequency and spontaneous specific locus mutation rates, it is possible to derive an estimate of the number of loci included in the recessive lethal test. The average number derived from three estimates on male and female germ cells in 563 loci. A second independent approach derives from published data which analyzed short regions of the genome and the proportion of loci within these regions whichmore » mutate to lethality. This analysis suggests that 830 loci are potentially lethal mutables. We describe the reasons for concluding that 600 to 800 loci of the approximately 1000 loci on the X-chromosome are involved in the X-linked recessive lethal test.« less
  • Productivity is a measure of how efficiently a company uses its resources. The productivity budgeting model (PBM) is one tool that can aid management in the transition from cost-plus, rate-of-return regulation to the market-oriented, cost-control environment of incentive regulation. Most, if not all, utilities use some type of budgeting/forecasting process that provides the blueprint for future company activity. The PBM reveals the growth in total factor productivity (TFP) implied by a budget and, thus, provides a forecast of the company's future efficiency. The PBM can be used to guide resource usage, because it analyzes investment, labor force, and operating decisionsmore » from an economic efficiency perspective. In general, the model makes the budgeting process more relevant to the kind of decisions utility management must make for long-term success under incentive regulation. Furthermore, under many incentive regulation. Furthermore, under many incentive regulation plans (such as the FCC's price-cap plan), a company must meet or beat the productivity offset to increase its profitability. With PBM, the company can determine whether its proposed budget is on track and devise a plan to meet any offset. The PBM can also be used to track productivity using financial data from the period in question.« less
  • We present a new assessment of the ability of Infrared Dark Clouds (IRDCs) to form massive stars and clusters. This is done by comparison with an empirical mass-size threshold for massive star formation (MSF). We establish m(r)>870 M {sub sun}(r/pc){sup 1.33} as a novel approximate MSF limit, based on clouds with and without MSF. Many IRDCs, if not most, fall short of this threshold. Without significant evolution, such clouds are unlikely MSF candidates. This provides a first quantitative assessment of the small number of IRDCs evolving toward MSF. IRDCs below this limit might still form stars and clusters of upmore » to intermediate mass, though (like, e.g., the Ophiuchus and Perseus Molecular Clouds). Nevertheless, a major fraction of the mass contained in IRDCs might reside in few 10{sup 2} clouds sustaining MSF.« less
