Thu, 11 Nov 2010 07:23:59 -0500 Them Wascally Gravity Waves http://www.drdobbs.com/parallel/them-wascally-gravity-waves/228701635 I opined in my January posting <a href="http://www.drdobbs.com/blog/archives/2010/01/elusive_gravity.html">Elusive Gravity Waves</a> that the <a href="http://www.ligo.caltech.edu/">LIGO Laser Interferometer Gravitational-Wave Observatory</a> experiment may be methodologically flawed. A recent (2010-10-06) paper <a href="http://arxiv.org/PS_cache/arxiv/pdf/1006/1006.2535v2.pdf">"First search for gravitational waves from the youngest known neutron star"</a> does little to disabuse one of such a notion. Mon, 11 Oct 2010 08:37:26 -0400 Insights on Infinite Subconstituency http://www.drdobbs.com/parallel/insights-on-infinite-subconstituency/228701403 I propose (again, but in better form) an interpretive model of quantum mechanics Sun, 04 Jul 2010 18:01:27 -0400 Quantum Computing and the search for the Higgs Boson http://www.drdobbs.com/parallel/quantum-computing-and-the-search-for-the/228701690 I'm betting that the Higgs Boson is not going to be detected in data gathered from the Large Hadron Collider ... not because I know anything, but because the quantum physics community will be happier (<em>felix</em>) if it is <em>not</em> found. Observation of Higgs Boson is necessary to further validate the Standard Model of particle physics. The HB is a sort of a quantum overhead bin into which the Almighty has surreptitiously stuffed the mass abstracted from the rest of Her luggage. If the Standard Model is validated by even a brief appearance of the Higgs Boson, science is left with a complete but unsatisfactory theory of the subatomic universe. On the other hand, if the Higgs Boson joins phlogiston and the aether in the bestiary of blown theories, science takes a new leap into exploring the dark places of the quantum mechanical universe instead of looking in the bright places as it does now. This could have a positive impact on quantum computing, where scientists and engineers are perforce exploring the dark places. Quantum computing could use a few more willing hands applied to the work. Tue, 15 Jun 2010 07:52:54 -0400 On the Quantum Computing Bus: A Chat with Steven M. Girvin http://www.drdobbs.com/parallel/on-the-quantum-computing-bus-a-chat-with/228700988 Computing with qubits beyond the simplest examples requires the ability to store, retrieve and communicate those qubits without losing their quantum state. <a href="http://www.seas.yale.edu/faculty-detail.php?id=37">Steven Girvin</a> is the Eugene Higgins Professor of Physics and Professor of Applied Physics at Yale University. His primary focus at present is on the quantum electrodynamics of microwave electrical circuits and quantum information processing with superconducting qubits and cavities. A 2007 paper on which Prof. Girvin collaborated, <a href="http://www.seas.yale.edu/admin/uploads/2071370137490f13ac72407.pdf">Coupling Superconducting Qubits via a Cavity Bus</a>, points in the direction of the sort of data bus necessary for meaningful quantum computing.

They have been in the news recently in the form of superconducting magnets for the <a href="http://en.wikipedia.org/wiki/LHC">Large Hadron Collider</a>.</p> Superfluids exhibit fluid dynamics analogous to the electrical dynamics of superconductors: they will flow through the finest capillaries without friction. The connection between superfluids and superconductors is more than an analogy: the quantum theories of the two phenomena are intimately related. </p> Prof. Sir Anthony (he was knighted in 2004) spoke with me by phone from his office. </p> Tue, 15 Dec 2009 19:00:00 -0500 Google is all over QC like flies on sugar http://www.drdobbs.com/architecture-and-design/google-is-all-over-qc-like-flies-on-suga/228701084 Google&#39;s not only watching your car for you, Google is all over quantum computing. </p> Mon, 14 Dec 2009 19:00:00 -0500 Russian rocket provides geometric analogy to quantum measurement coincidence http://www.drdobbs.com/architecture-and-design/russian-rocket-provides-geometric-analog/228701086 A Wired reprint of a <a href="http://www.wired.com/wiredscience/2009/12/norway-spiral-in-the-sky/">Norwegian photo of the spiral cloud</a> left by a Russian rocket spinning out of control illustrates a geometric analogy to a paradox of quantum entanglement. </p> Sat, 12 Dec 2009 19:00:00 -0500 Drowning Man Grasps Planck http://www.drdobbs.com/architecture-and-design/drowning-man-grasps-planck/228701090 <img src="http://upload.wikimedia.org/math/9/5/9/9594901b51008ac92c2709a69122a120.png" alt="E = h\nu.\," title="E = h\nu.\," /></p> Drowning in the ocean of quantum field theory, your correspondent grasps Planck and emerges to sputter another question. </p> Tue, 01 Dec 2009 19:00:00 -0500 Onion Theory of the Universe http://www.drdobbs.com/architecture-and-design/onion-theory-of-the-universe/228700059 Wed, 25 Nov 2009 19:00:00 -0500 A rotating disc replicates the prediction of quantum mechanics http://www.drdobbs.com/architecture-and-design/a-rotating-disc-replicates-the-predictio/228700792 &quot;[R]enunciation of the visualisation of atomic phenomena is imposed upon us by the impossibility of their subdivision ...&quot; - <a href="http://en.wikipedia.org/wiki/Niels_Bohr">Niels Bohr</a>, <a href="http://www.marxists.org/reference/subject/philosophy/works/dk/bohr.htm">Discussions with Einstein on Epistemological Problems in Atomic Physics</a></p> A thought experiment follows in which a visualizable model of a rotating disc replicates the prediction of quantum mechanics with respect to coincidence of observation of entangled particles. </p> Sun, 22 Nov 2009 19:00:00 -0500 No Starch publisher Bill Pollock on Ryan Harris indictment http://www.drdobbs.com/architecture-and-design/no-starch-publisher-bill-pollock-on-ryan/228700581 <a href="http://nostarch.com/cablemodem.htm"><img src="http://nostarch.com/images/cablemodem_cov.jpg" border="1" alt=" Cover of Hacking the Cable Modem" title=" Cover of Hacking the Cable Modem" hspace="4" width="155" height="204" align="left" /></a> In lurid language <a href="http://www.wired.com/threatlevel/2009/11/derengel/">Wired reports</a> that <a href="ttp://blogs.zdnet.com/threatchaos/?p=436">Ryan &quot;DerEngel&quot; Harris</a>, author of <a href="http://nostarch.com/cablemodem.htm">Hacking the Cable Modem</a> , has been federally indicted for &quot;aiding computer intrusion&quot; for his business of selling unlocked cable modems.</p> Bill Pollock is the founder of <a href="http://nostarch.com/index.htm">No Starch Press</a>, Harris&#39;s publisher, which issued a press release <a href="http://nostarch.com/releases/cablemodem.html" target="new">No Starch Press Publisher Speaks Out on Hacking and Free Speech</a>.
