Please Read How You Can Help Keep the Encyclopedia Free Quantum Logic and Probability Theory First published Mon Feb 4, 2002; substantive revision Mon Feb 27, 2006 At its core, quantum mechanics can be regarded as a non-classical probability calculus resting upon a non-classical propositional logic. More specifically, in quantum mechanics each probability-bearing proposition of the form "the value of physical quantity A lies in the range B " is represented by a projection operator on a Hilbert space H . These form a non-Boolean in particular, non-distributive orthocomplemented lattice. Quantum-mechanical states correspond exactly to probability measures (suitably defined) on this lattice. What are we to make of this? Some have argued that the empirical success of quantum mechanics calls for a revolution in logic itself. This view is associated with the demand for a realistic interpretation of quantum mechanics, i.e., one not grounded in any primitive notion of measurement. Against this, there is a long tradition of interpreting quantum mechanics operationally, that is, as being precisely a theory of measurement. On this latter view, it is not surprising that a "logic" of measurement-outcomes, in a setting where not all measurements are compatible, should prove not to be Boolean. Rather, the mystery is why it should have the particular non-Boolean structure that it does in quantum mechanics. A substantial literature has grown up around the programme of giving some independent motivation for this structure ideally, by deriving it from more primitive and plausible axioms governing a generalized probability theory.

The development follows the near-perfect cloning of quantum bits by physicists at the University of Oxford earlier this year. In conventional electronics, a NOT gate inverts the value of a bit of information from 1 to or from to 1. This works because ordinary bits can only have a value of 1 or 0. Physicists have long believed that such binary information could also be stored in certain two-state quantum systems, such as the horizontal and vertical polarization states of photons, or the spin-up and spin-down states of electrons. One of these entangled photons travelled to a detector, which measured its polarization, while a mirror reflected its partner back into the crystal. When this reflected photon emerged from the crystal, a second detector measured its polarization.

10. Quantum Reality Quantum Reality describes eight of these candidate realities ranging from Hugh Everett s ManyWorlds Model thru Quantum logic and Undivided Wholeness to http://www2.cruzio.com/~quanta/qreality1.html

Order Quantum Reality from amazon.com QUANTUM REALITY: BEYOND THE NEW PHYSICS One of the best-kept secrets of sciencea veritable skeleton in the science closetis the fact that physicists have lost their grip on reality. Quantum theory is the most comprehensive and accurate theory known to man, describing nature at all scales from quark to quasar and forming the foundation for numerous technologies including lasers, semiconductors and nuclear power. But the price physicists have paid for this powerful theory is the loss of an overall picture of how the world works. "Who could have imagined", Einstein once remarked about this reality crisis in physics, "that we would come to know so much yet understand so little?" Quantum theory describes the world in terms of wave-like possibilities, when not observed; which change into (the so-called "collapse of the wavefunction") particle-like actualities (quanta) when looked at. Particles when you look; waves when you don't. What a strange way physicists have of dealing with the ordinary world! And to make things worse not one of us can tell you what it means to "look". "What is an observation?" is the biggest unsolved question in physics. The problem of observation lies at the the heart of the physicist's reality crisis. "Quantum Reality" examines what "reality" means to a physicist including case histories of a reality that failed (the luminiferous ether) and a reality that succeeded (the atomicity of matter). Besides not being able to say what they mean by "observation", one further symptom of the reality crisis is the number of candidate realities proposed to explain the same quantum facts: all of these quantum realities are bizarre and none of them quite satisfactory.

Quantum Logic : Order Structures in Quantum Mechanics Order structures in quantum mechanics have rather recently become subject of research. Their study follows the intention to gain insight into categorial communities and differences between classical and quantum mechanics . As one possible answer to this problem, Marlow stated with respect to Quantum Logic "Quantum theory is simply the replacement in standard probability theory of event-as-subset-of-a-set (abelian, distributive) by event-as-subspace-of-a-Hilbert-space (non-abelian, non-distributive)" Read this introduction by Martin Ziegler to understand what he means by that.

(issue of 1 February 1999) Title and Authors 4 February 1999 Quantum Logic with an Optical Lattice Ivan Deutsch/University of New Mexico Laser egg carton. Interfering laser beams can hold atoms in a precise array. In this arrangement, the atoms could form the basis for a quantum computer. Quantum computers could potentially calculate much faster than the silicon-based computers of today. Their advantage is that quantum computer bits can remain in two states at once as they perform operations, unlike conventional bits, which must commit to "0" or "1." The problem for designers is that these quantum bits (qubits) must remain well isolated to preserve their quantum nature, and yet be easily accessible for manipulation by the computer. The 1 February PRL describes a new type of quantum logic gate that might, at least in theory, meet those seemingly contradictory requirements. Researchers suggest that neutral atoms trapped in an optical latticea series of potential wells created by the interference of laser beamsmight offer advantages over the charged ions and atomic nuclei that are currently used. One of the most promising ways to build a quantum computer so far has been to trap ultracold charged ions in electric fields and manipulate them using lasers. But since these ions are charged, they interact readily with stray electric fields in the environment and are thus extremely susceptible to decoherencea loss of quantum character that prevents qubits from remaining in two states. Ivan Deutsch of the University of New Mexico in Albuquerque and Poul Jessen of the University of Arizona in Tucson and their colleagues propose using neutral atoms trapped in an optical lattice for quantum computing. Neutral atoms, they reason, will be less willing to interact with their environment. Moreover, atoms trapped in different wells of an optical lattice hardly influence one another, so a million atoms can potentially be operated upon at once.

Introducing a monthly newsletter from the editors of TRN - the latest on the littlest Optics demo does quantum logic April 6/13, 2005 Researchers from the University of Science and Technology of China and the University of Heidelberg in Germany have demonstrated a method of using four photons to form a logic gate that can be used for quantum computing. Quantum computers use attributes of particles like atoms, photons and electrons to represent information, and manipulate the particles to carry out computations. Quantum computers have the potential to solve certain very large problems that are beyond the capabilities of the fastest possible classical computer. The researchers' logic gate is a step toward making quantum computers practical. Logic gates that link pairs of quantum bits, which represent single bits of binary information, are essential to quantum computing. It has been difficult to form two-bit logic gates from photons rather than electrons or atoms because photons interact very weakly, essentially passing through each other unaltered. At the same time, photons are especially useful as qubits because they can be transported over communications lines. The researchers' proof-of-principal experiment demonstrated that it is possible to make a non-destructive photonic Controlled-NOT, or CNOT, gate that uses linear optical elements.

Duncan Steel of the University of Michigan and co-workers have created a logic gate using two electron-hole pairs - also known as "excitons" - in a quantum dot (X Li et al. Science Classical computers deal with binary logic and the bits being processed must be either "0" or "1". Quantum computers, on the other hand, exploit the ability of quantum particles to be in two or more states at the same time. A quantum bit or "qubit" can therefore be "0" or "1" or any combination of the two. This means that a quantum computer could, in principle, outperform a classical computer for certain tasks. However, all the quantum computers demonstrated so far have only contained a handful of qubits. Although qubits have been made with trapped photons, atoms and ions, it is generally thought that it should be easier to build working devices with solid-state systems. Several teams have made significant progress with the superconducting approach to solid-state quantum computing. Now Steel and co-workers at Michigan, Michigan State, the Naval Research Laboratory and the University of California at San Diego have demonstrated the first all-optical quantum gate in a semiconductor quantum dot.

RAPID SINGLE-FLUX-QUANTUM LOGIC K.K. LIKHAREV Department of Physics State University of New York Stony Brook, NY 11794-3800 U.S.A. ABSTRACT . Background, basic ideas, and recent development of a new family of ultrafast superconductor digital devices are reviewed. Possible applications of this new digital technology are discussed. 1. Introduction Since the late 1960s it has become clear that several features of Josephson-junction integrated digital circuits may make them uniquely suitable for fast processing of digital information. These features include: Availability of superconducting microstrip transmission lines capable of transferring picosecond waveforms over virtually any interchip distance with a speed approaching that of light, and low attenuation and dispersion - see, e.g., theoretical analyzes by Kautz (1979) and Ekholm (1990) and experiments by Andratsky et al. (1990) and Polonsky et al. (1993b). It is also very important that these lines can be quite densely laid out (since spacing between the lines and their width are limited only by the available patterning technology), while having low crosstalk. Availability of Josephson junctions which can serve as ultrafast (picosecond) switches. Simultaneously, the junctions can be impedance-matched with the superconductor microstrip lines. This property allows one to ensure the ballistic transfer of the generated waveforms along the lines. Finally, even at these low impedances (R~10 Ohms) the Josephson junction power consumption P = V

22. NIST: First Steps Toward Realization Of Quantum-Logic The starting point in the development of practical Quantumlogic systems at NIST involved the convergence to two lines of study. Beginning in the early 80s http://qubit.nist.gov/firstSteps.html

The First Steps Toward Realization of Quantum-Logic at NIST The starting point in the development of practical quantum-logic systems at NIST involved the convergence to two lines of study. Beginning in the early '80s, Feynman [ ] and Benioff speculated on the possibility of using quantum systems to perform (reversible) computation. Deutsch ] expanded on these ideas, showing that certain computations could be performed more efficiently using quantum systems. In 1994, Peter Shor ] made a significant advance when he developed a quantum-logic algorithm that could factor large numbers efficiently. But no one had yet devised a practical approach for building a quantum computer. During this same period, Wineland and his colleagues in the Ion Storage Group at NIST, Boulder, Colorado, were working on laser-cooled ions stored in electromagnetic traps for high-performance frequency standards . There are many advantages to be gained by using stored ions for this application, but one disadvantage is that the most promising approach uses only a few ions, and the signal-to-noise ratio is thus small. In order to deal with this problem, the Ion Storage Group developed a concept for reducing the noise below the usual quantum limit [ ] through what can be called "spin squeezing," [

QUANTUM GRAVITATIONAL VS. QUANTUM LOGIC: VIRTUALLY LEFT-HANDED REAL TRINARY LOGIC Where , and 1 = 0, and 00 = = 1, the cornerstone, Precisely as infinite, the infinite lattice is not able to be mirrored, as it is not able to be gotten outside of. In fact, where , and 1 = 0, and 00 = for 1, producing the right-handed U-diagonal, where the following relations obtain: 0U = 1, 10 = U, 1U = 0, and 11 = 1, but 00 = 0, UU = U, and UU 11, that is, U That such a right-handed trinary logic the virtual reverse and reduction of real trinary logic to the logic of superpositional intermediation is radically binary, literally can be seen in the form of the infinitely expanding triangle produced by the infinite iterative sequential summing of the logical sequence, 1, 0, U, 1, 0, U, 1, 0, U, . . ., where the logical operator is Hellerstein's "pivot," as here illustrated The radically binary 2-based nature of right-handed trinary logic is further manifest in the fact that the sequence of the number of U's constituting the edges of the edge-sharing triangles of U's whose hypotenuses extend to the edges of the major infinitely expanding triangle is 2, 5, 14, 41, 122, . . ., that is, where x = 3, this sequence is 2, 2 +

29. Logic As Boolean Quantum Field Theory Perhaps one could say that Quantum logic is Cvalued in the sense that all complex superpositions of a statement and its negation are possible. http://www.helsinki.fi/~matpitka/qlogic.html

Postal address: Department of Physics, Theoretical Physics Division, P.O. Box 9 Fin-00014, University of Helsinki, Finland E-mail matpitka@rock.helsinki.fi URL-address http://blues.helsinki.fi/~matpitka Illustrations about TGD and TGD inspired theory of consciousness Logic as Boolean QFT and fermionic QFT as complex valued logic The simplest TGD based model for thinking systems leads to the result that thoughts correspond to quantum states in discrete spaces. The reason is that slightly nondeterministic classical time evolution means a finite number of bifurcations. These additional dynamical degrees of freedom correspond to N-element set labelling the different time evolutions associated with given initial values. Furthermore, the entanglement between two p-adic subsystems (say me and the external world spacetime sheet) with different values of the p-adic prime must be binary. This suggests that a suitably defined binary Hilbert space having Z_2 rather than complex numbers as a coefficient field could provide a simple quantum model for a thinking system. This raises the question: What would a quantum field theory in discrete space and with the field of complex numbers replaced with binary numbers Z_2 (0,1/Yes,No) look like?

Full text available as: Preview PDF - Requires a PDF viewer such as GSview Xpdf or Adobe Acrobat Reader Preview Postscript - Requires a viewer, such as GSview Abstract The quantum logical `or' is analyzed from a physical perspective. We show that it is the existence of EPR-like correlation states for the quantum mechanical entity under consideration that make it nonequivalent to the classical situation. Specifically, the presence of potentiality in these correlation states gives rise to the quantum deviation from the classical logical `or'. We show how this arises not only in the microworld, but also in macroscopic situations where EPR-like correlation states are present. We investigate how application of this analysis to concepts could alleviate some well known problems in cognitive science.

The Leading Source for Global News and Information Covering the Ecosystem of High Productivity Computing / March 10, 2006 Home Page Free Subscription Advertising About HPCwire Hardware: AIST Fabricates Logic Gate for Quantum Computers The National Institute of Advanced Industrial Science and Technology (AIST) has successfully developed the world's first basic device structure extendable to multi-quantum-bits for an optically controlled quantum logic gate. This achievement is part of the "Core Research For Evolutional Science and Technology (CREST)" project of the Japan Science and Technology Agency (JST). Quantum computers are expected to be able to process huge amounts of information so that they can rapidly solve problems that take even supercomputers a long time. Because of this, organizations in many countries have been working on their development. Basic devices for quantum computers must have a structure enabling small size and multi-bit integration. Recently, many studies on quantum bits (qubits) and quantum logic gates using solid-state materials such as superconductors and semiconductors have been reported. For devices utilizing excitons (electron-hole pairs) in semiconductors, optically-controlled ultra-high speed processing (a computing step of pico-seconds) is possible. However, there have been no reports on basic device structures which enable both "multi-bit" and strong "interaction between the two qubits," which are essential for quantum logic gates. Thus, recent work has focused on developing such quantum logic gates.

About   NSF Grant to Fund Quantum Logic Technologies A team of chemists, physicists and engineers at the University of California, Berkeley, has received $4.5 million from the National Science Foundation (NSF) to test whether several cutting-edge technologies are suitable for building the first practical quantum computer. The problem with the technologies that proved quantum computing possible is that they will not scale up to the size of quantum processors, which involve hundreds or thousands of quantum bits, or qubits, said project leader K. Birgitta Whaley, professor of chemistry. Her group will look beyond these technologies to explore the feasibility of solid state quantum computers, which are scalable. "Our goal is to find a material that would make a practical quantum nanoprocessor," she said.

Home QUANTUM LOGIC DEVICES WILL BE PRESENTING AT WORLD’S BEST TECHNOLOGIES SHOWCASE Submitted by Unregistered on May 11, 2007 - 15:39. Category tags: Press release News and information companies and sites Austin, TX [May 10, 2007] Quantum Logic Devices announced today that it will be presenting its revolutionary nanoelectronic biodetection platform at the World’s Best Technologies Showcase (WBT) in Arlington, Texas. WBT will be held in the Arlington Convention Center from May 15-16. QLD’s bio-transistors are the same size as proteins (about 10 nanometers) and are switched on or off by the reactions of attached molecular probes. For example, the binding of a single antibody on the device results in an electrical signal indicating the presence of a virus in fluid sample. The technology avoids many of the complexities and high costs of using fluorescent optical dyes, and provides higher sensitivity in less time. Because of the electronic detection method, samples that are inaccessible to optical techniques – such as blood or urine – can be analyzed by QLD’s platform directly.

Chapter 7. Logic with Vectors: Ambiguous Words and Quantum States As we try to learn and reason about language and its meaning by measuring the distributions of points and regions in geometric models, a variety of powerful logical operators become available. Many such operators correspond to well-known logic gates in computer science, and to familiar options in standard user interfaces. A typical example is shown in Figure 7.1. In many browsers and user interfaces (in the year 2004), if you click on one icon and then click on another, the second will become selected and this will cancel the selection of the first, and if you click on more icons, the one most recently selected becomes the unique active icon, overiding previous selections. However, if you hold down the CTRL key and then click on two different icons, both icons will be selected. And if you hold down the SHIFT key and then click, both icons and those in between will be selected. When using these features, previous selections are not discarded - all the icons selected while holding down the correct key are combined to give a special set of selected items. The processes of combination correspond to disjunctions OR operators or joins ) in different logics.

How new technologies are modifying our way of life Web www.primidi.com Quantum Logic Gate Created Using Excitons In this article , PhysicsWeb reports that researchers in the U.S. "have taken another important step towards making a quantum computer . [They] have created a logic gate using two electron-hole pairs also known as "excitons" in a quantum dot." Before going further, what is an exciton? Here is the definition from Wikipedia An exciton is a combination of an electron and a hole in a semiconductor or insulator in an excited state. The hole behaves as a positive charge, and the electron is attracted to it to form an "exotic atom" state akin to that of a hydrogen atom. The probability of the electron falling into the hole is limited by the difficulty of losing the excess energy, so that the exciton may have a relatively long life. The existence of these states may be inferred from the absorption of light associated with their excitation. Alternatively, an exciton may be thought of as an excited state of an atom or ion, the excitation wandering from one cell of the lattice to another. So what exactly did these researchers?

Printing Tips : Select 'print as image' in the Acrobat print dialog if you have trouble printing. ABSTRACT: We solve the Jaynes-Cummings Hamiltonian with time-dependent coupling parameters under the dipole and rotating-wave approximations for a three-dimensional photonic crystal (PC) single-mode cavity with a sufficiently high-quality Q factor. We then exploit the results to show how to create a maximally entangled state of two atoms and how to implement several quantum logic gates: a dual-rail Hadamard gate, a dual-rail NOT gate, and a SWAP gate. The atoms in all of these operations are syncronized, which is not the case in previous studies of PCs [J. Mod. Opt. 48, 1495 (2001); Ear. Phys. J. D 10, 285 (2000); Eur. Phys. J. D 18, 247 (2002)]. Our method has the potential for extension to N-atom entanglement, universal quantum logic operations, and the implementation of other useful, cavity QED-based quantum information processing tasks.
