Logic To Physics. New analysis eliminates a potential speed bump in quantum computing. Global symmetry not required for fast quantum search A quantum particle can search for an item in an unsorted “database” by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
This assertion assumes, however, that the particle can directly hop from any item to any other. Any restriction on which items the particle can directly hop to could slow down the search.A quantum particle can search for an item in an unsorted “database” by jumping from one item to another in superposition, and it does so faster than a classical computer ever could. Henry Stapp. Henry Stapp (born 1928) is an American physicist, known for his work in quantum mechanics.[1] Biography[edit] Stapp received his PhD in particle physics at the University of California, Berkeley, under the supervision of Nobel Laureates Emilio Segrè and Owen Chamberlain.

Plasmon. In physics , a plasmon is a quantum of plasma oscillation .
The plasmon is a quasiparticle resulting from the quantization of plasma oscillations just as photons and phonons are quantizations of electromagnetic and mechanical vibrations, respectively (although the photon is an elementary particle , not a quasiparticle). Thus, plasmons are collective oscillations of the free electron gas density, for example, at optical frequencies. Plasmons can couple with a photon to create another quasiparticle called a plasma polariton . Since plasmons are the quantization of classical plasma oscillations, most of their properties can be derived directly from Maxwell's equations .
Binding problem. The binding problem is a term used at the interface between neuroscience, cognitive science and philosophy of mind that has multiple meanings.
Firstly, there is the segregation problem: a practical computational problem of how brains segregate elements in complex patterns of sensory input so that they are allocated to discrete "objects". In other words, when looking at a blue square and a yellow circle, what neural mechanisms ensure that the square is perceived as blue and the circle as yellow, and not vice versa? The segregation problem is sometimes called BP1. Secondly, there is the combination problem: the problem of how objects, background and abstract or emotional features are combined into a single experience.[1] The combination problem is sometimes called BP2.
However, the difference between these two problems is not always clear. The segregation problem[edit] Quantum entanglement isn't only spooky, you can't avoid it. Quantum entanglement is the key to quantum computing, cryptography, and numerous other real-world applications of quantum mechanics.
It is also one of the strangest phenomena in the Universe, overcoming barriers of space and time and knitting the entire cosmos into an integrated whole. Scientists have long thought that entanglement between two particles was a rare and fleeting phenomenon, so delicate that exposure of the particles to their surroundings would quickly destroy this linkage. Now mathematicians at Case Western University have shown that entanglement between parts of large systems is the norm, rather than being a rare and short-lived relationship. Entanglement is one of the strangest predictions of quantum mechanics. Two objects are entangled if their physical properties are undefined but correlated, even when the two objects are separated by a large distance.
Quantum entanglement in photosynthetic light-harvesting complexes : Nature Physics. Light-harvesting components of photosynthetic organisms are complex, coupled, many-body quantum systems, in which electronic coherence has recently been shown to survive for relatively long timescales, despite the decohering effects of their environments.
Here, we analyse entanglement in multichromophoric light-harvesting complexes, and establish methods for quantification of entanglement by describing necessary and sufficient conditions for entanglement and by deriving a measure of global entanglement. These methods are then applied to the Fenna–Matthews–Olson protein to extract the initial state and temperature dependencies of entanglement. We show that, although the Fenna–Matthews–Olson protein in natural conditions largely contains bipartite entanglement between dimerized chromophores, a small amount of long-range and multipartite entanglement should exist even at physiological temperatures.
Whaley Group - Publications. Quantum Effects in Biological Environments (QUBE) The Quantum Effects in Biological Environments (QuBE) program is laying the foundation for novel sensor designs by challenging the long-held view that biological sensors utilize primarily classical physics Biological sensors often display high sensitivity, selectivity, and low false alarm rates while being fabricated and operated in dirty, noisy natural environments.
Attempts to emulate these sensors synthetically have not fully met expectations. Recent evidence suggests that some biological sensors exploit nontrivial quantum mechanical effects to produce macroscopic output signals. Examples of such sensors include the highly efficient energy transfer properties of photosynthesis in plants, bacteria, and algae; magnetic field sensing used by some birds for navigation; and the ability of some animals to detect odors at the single molecule level.

Being in two places at once. Communicating information seemingly faster than the speed of light. Wave function. However, complex numbers are not necessarily used in all treatments. Louis de Broglie in his later years proposed a real-valued wave function connected to the complex wave function by a proportionality constant and developed the de Broglie–Bohm theory. The unit of measurement for ψ depends on the system. For one particle in three dimensions, its units are [length]−3/2. John S. Bell. Ontology. Study of the nature of being, becoming, existence or reality, as well as the basic categories of being and their relations Parmenides was among the first to propose an ontological characterization of the fundamental nature of reality. Etymology[edit] While the etymology is Greek, the oldest extant record of the word itself, the New Latin form ontologia, appeared in 1606 in the work Ogdoas Scholastica by Jacob Lorhard (Lorhardus) and in 1613 in the Lexicon philosophicum by Rudolf Göckel (Goclenius).
The first occurrence in English of ontology as recorded by the OED (Oxford English Dictionary, online edition, 2008) came in a work by Gideon Harvey (1636/7–1702): Archelogia philosophica nova; or, New principles of Philosophy. Leibniz is the only one of the great philosophers of the 17th century to have used the term ontology.[6] Entangled diamonds vibrate together. A pair of diamond crystals has been linked by quantum entanglement. This means that a vibration in the crystals could not be meaningfully assigned to one or other of them: both crystals were simultaneously vibrating and not vibrating.
Quantum entanglement — interdependence of quantum states between particles not in physical contact — has been well established between quantum particles such as atoms at ultra-cold temperatures. But like most quantum effects, it doesn't tend to survive either at room temperature or in objects large enough to see with the naked eye. Laurent Nottale. Laurent Nottale (born 29 July 1952) is an astrophysicist, a director of research at CNRS, and a researcher at the Paris Observatory. He is the author and inventor of the theory of Scale Relativity which aims to unify quantum physics and relativity theory.
Scientific career[edit] He also published a popular book L'Univers et la Lumière, Flammarion, Nouvelle Bibliothèque Scientifique 1994, Champs 1998) for which he received a prize in 1995 (Prix du livre d'Astronomie Haute-Maurienne-Vanoise).

Superposition principle. Superposition of almost plane waves (diagonal lines) from a distant source and waves from the wake of the ducks. Linearity holds only approximately in water and only for waves with small amplitudes relative to their wavelengths. In physics and systems theory, the superposition principle,[1] also known as superposition property, states that, for all linear systems, the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually.
So that if input A produces response X and input B produces response Y then input (A + B) produces response (X + Y). The homogeneity and additivity properties together are called the superposition principle. Origin of life: Quantum mechanics provided the … ooomph!! ?
