Modern Privacy Advocacy: An Approach at War with Privacy Itself?
This Article argues that the modern concept of privacy itself, particularly as framed by some of its most ardent advocates today, is fundamentally incoherent. The Article highlights that many common arguments made in support of privacy, while initially seeming to protect this critical value, nonetheless undermine it in the long run. Using both recent and older examples of applying classic privacy advocacy positions to key technological innovations, the authors demonstrate how these positions, while seemingly privacy-enhancing at the time, actually resulted in outcomes that were less beneficial for consumers and citizens, including from a purely privacy-focused perspective. As a result, the authors advocate for a privacy approach that focuses on the long-term results of particular proposals rather than the immediate results in a given circumstance

Distribution of interference in random quantum algorithms
We study the amount of interference in random quantum algorithms using a
recently derived quantitative measure of interference. To this end we introduce
two random circuit ensembles composed of random sequences of quantum gates from
a universal set, mimicking quantum algorithms in the quantum circuit
representation. We show numerically that these ensembles converge to the
well--known circular unitary ensemble (CUE) for general complex quantum
algorithms, and to the Haar orthogonal ensemble (HOE) for real quantum
algorithms. We provide exact analytical formulas for the average and typical
interference in the circular ensembles, and show that for sufficiently large
numbers of qubits a random quantum algorithm uses with probability close to one
an amount of interference approximately equal to the dimension of the Hilbert
space. As a by-product, we offer a new way of efficiently constructing random
operators from the Haar measures of CUE or HOE in a high dimensional Hilbert
space using universal sets of quantum gates.Comment: 14 pages revtex, 11 eps figure
Influence of Boehmite Precursor on Aluminosilicate Aerogel Pore Structure, Phase Stability and Resistance to Densification at High Temperatures
Aluminosilicate aerogels are of interest as constituents of thermal insulation systems for use at temperatures higher than those attainable with silica aerogels. It is anticipated that their effectiveness as thermal insulators will be influenced by their morphology, pore size distribution, physical and skeletal densities. The present study focuses on the synthesis of aluminosilicate aerogel from a variety of Boehmite (precursors as the Al source, and tetraethylorthosilicate (TEOS) as the Si source, and the influence of starting powder on pore structure and thermal stability
