Quantum Computers Could Tackle Enormous Linear Equations

A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control.

...or Internet traffic scanning and analysis, we should add.

The new work, published October 7 in Physical Review Letters, may dramatically expand the range of potential uses for quantum computers.

An earlier version of the article: June 2, 2009

In the new study, Aram Harrow of the University of Bristol in England along with Avinatan Hassidim and Seth Lloyd, both of MIT, propose that large datasets of linear equations could be encoded in quantum forms, such as the spins of nuclei, individual atoms or photons. Such a system would allow quantum computers to handily solve problems made up of billions or even trillions of variables...

...thus raising the encryption bar even further. But, in the same issues of of Physical Review Letters and Science News, we find:

Entangled Photons Make Better Messengers

Quantum communication offers an absolutely secure way to send secret messages, such as encoded military secrets or financial transactions. But quantum information is fragile, quickly destroyed by even slight interactions with the environment.

While a conventional bit of information can have only one value, 0 or 1, a quantum bit, or qubit, exists as a combination of 0 and 1 simultaneously. A qubit stays in this undecided state until something, whether a stray atom or a scientist trying to measure its properties, interacts with it, forcing it into a single state. This collapse of possibilities, known as quantum decoherence, can be detected farther down the line to catch eavesdroppers. But it can also keep qubits from reaching their destination intact.

Fortunately, theorists have shown that some quantum-mechanical systems are immune to certain interactions...

Zeno is pro Darwin: Quantum Zeno Effect Suppresses the Dependence of Radical-Ion-Pair Reaction Yields on Exchange and Dipolar Interactions

Author: I. K. Kominis

Abstract: A biochemical quantum sensor of magnetic fields, namely magnetic-sensitive radical-ion-pair reactions, is understood to underlie avian magnetic navigation. It has been recently postulated [O. Efimova and P. J. Hore, Biophys. J. {\bf 94}, 1565 (2008)] that a fine-tuned cancellation of exchange and dipolar interactions in necessary for this magnetic sensor to function at earth's field. We here show that if the basic parameters of the radical-ion-pair are such that the quantum Zeno effect is manifested, the dependence of the magnetic-sensitive reaction yields on molecule-specific exchange and dipolar interactions is almost entirely suppressed. A fundamental quantum effect is thus shown to provide for the robustness of this biochemical sensor.

Scaling Up Entanglement

Perhaps this sort of thing is already taking place in your (human) brain, but the rudiments of a mechanical system of quantum entanglement have been demonstrated with separate, oscillating pairs of beryllium and magnesium ions, as reported by Jost et al in the June 4 edition of Nature...

Entangled mechanical oscillators

NSA Will Use This

In diversionary cloaking, EM waves are scooted around an object (for illustration, see the Skilluminati article, Dreaming 5GW: Invisible War) The disadvantage here however is that the object is in a sense hermetically sealed from the environment, rendered incommunicado by its cloak.

A new method avoids this disadvantage by scattering EM waves in a manner similar to noise-cancellation devices. Says Nader Engheta in Science News, Cloaked Eye Still Sees:

“We are asking the question, ‘Is it possible to put a layer around an object such that when a wave hits the object, the wave scatters less?’ If the cloak is designed properly, the effect is reduced, like a cancelling effect... It puts in balance the object and the cloak.”

Hence, NSA listening posts will go undetected... And bug-detection manufacturers would be wise now to invest in more R&D.

Violation of smooth observable macroscopic realism in a harmonic oscillator

Authors: Amir Leshem, Omri Gat

(Submitted on 5 Feb 2009)

Abstract: We study the emergence of macrorealism in a harmonic oscillator subject to consecutive measurements of a squeezed action. Since the harmonic oscillator dynamics admits a hidden trajectory formulation, the assumptions of macrorealism are violated only by the measurement process. We demonstrate a breakdown of macrorealism in a wide parameter range that is maximized in a scaling limit of extreme squeezing. A semiclassical analysis shows that macrorealism is violated even with measurements of classically smooth observables that do not resolve quantum levels. We propose an experimental test of macrorealism with entangled photons by demonstrating that local realism in a composite system implies macrorealism in a subsystem.

The emergence of gravity as a retro-causal post-inflation macro-quantum-coherent holographic vacuum Higgs-Goldstone field

Authors: Jack Sarfatti, Creon Levit

(Submitted on 31 Jan 2009)

Abstract: We present a model for the origin of gravity, dark energy and dark matter: Dark energy and dark matter are residual pre-inflation false vacuum random zero point energy (w=-1) of large-scale negative, and short-scale positive pressure, respectively, corresponding to the "zero point" (incoherent) component of a superfluid (supersolid) ground state. Gravity, in contrast, arises from the 2nd order topological defects in the post-inflation virtual "condensate" (coherent) component. We predict, as a consequence, that the LHC will never detect exotic real on-mass-shell particles that can explain dark matter. We also point out that the future holographic dark energy de Sitter horizon is a total absorber (in the sense of retro-causal Wheeler-Feynman action-at-a-distance electrodynamics) because it is an infinite redshift surface for static detectors. Therefore, the advanced Hawking-Unruh thermal radiation from the future de Sitter horizon is a candidate for the negative pressure dark vacuum energy.

Determinism not dead

Can quantum mechanics be an emergent phenomenon?

Massimo Blasone, Petr Jizba, Fabio Scardigli
(Submitted on 26 Jan 2009)
Abstract: We raise the issue whether conventional quantum mechanics, which is not a hidden variable theory in the usual Jauch-Piron's sense, might nevertheless be a hidden variable theory in the sense recently conjectured by G. 't Hooft in his pre-quantization scheme. We find that quantum mechanics might indeed have a fully deterministic underpinning by showing that Born's rule naturally emerges (i.e., it is not postulated) when 't Hooft's Hamiltonian for be-ables is combined with the Koopmann - von Neumann operatorial formulation of classical physics.
