163. Quantum Communication - Short Introduction A short introduction titled quantum communication moves into the unknown by David Deutsch and Artur Ekert. http://eve.physics.ox.ac.uk/NewWeb/Research/communication/communication.html

Quantum communication moves into the unknown By David Deutsch and Artur Ekert Information is physical and any processing of information is always performed by physical means - an innocent-sounding statement, but its consequences are anything but trivial, In the last few years there has been an explosion of theoretical and experimental innovations which, their discoverers claim, are creating a fundamental new discipline: a distinctively quantum theory of information. Quantum physics allows the construction of qualitatively new types of logic gates, absolutely secure cryptosystems (systems that combine communications and cryptography), the cramming of two bits of information into one physical bit and, as has just been proposed, a sort of "teleportation", Here we describe the last two "miracles". Classical information theory agrees with everyday intuition: if you want to send a message using an object which can be put into one of N distinguishable states, the maximum number of different messages that you can send is N . For example, a single photon can have only two distinguishable polarisation states, say "left-handed" and "right-handed". So if you send a message by preparing the polarisation of a single photon and transmitting it, it is obvious that you can send no more than two distinguishable messages, i.e, one bit of information. 0bvious, but false.

Quantum Physics, abstract quant-ph/0004090 From: Richard MacKenzie [ view email ] Date: Mon, 24 Apr 2000 13:58:03 GMT (56kb) Path Integral Methods and Applications Authors: Richard MacKenzie Comments: 55 pages, 23 figures. Lectures given at Rencontres du Vietnam: VIth Vietnam School of Physics, Vung Tau, Vietnam, 27 December 1999 - 8 January 2000 Report-no: UdeM-GPP-TH-00-71 These lectures are intended as an introduction to the technique of path integrals and their applications in physics. The audience is mainly first-year graduate students, and it is assumed that the reader has a good foundation in quantum mechanics. No prior exposure to path integrals is assumed, however. The path integral is a formulation of quantum mechanics equivalent to the standard formulations, offering a new way of looking at the subject which is, arguably, more intuitive than the usual approaches. Applications of path integrals are as vast as those of quantum mechanics itself, including the quantum mechanics of a single particle, statistical mechanics, condensed matter physics and quantum field theory. After an introduction including a very brief historical overview of the subject, we derive a path integral expression for the propagator in quantum mechanics, including the free particle and harmonic oscillator as examples. We then discuss a variety of applications, including path integrals in multiply-connected spaces, Euclidean path integrals and statistical mechanics, perturbation theory in quantum mechanics and in quantum field theory, and instantons via path integrals.

166. The EPR Paradox And Bell's Inequality Principle A short article from the USENET physics FAQ. http://math.ucr.edu/home/baez/physics/Quantum/bells_inequality.html

[Physics FAQ] Updated May 1996 by PEG (thanks to Colin Naturman). Updated August 1993 by SIC. Original by John Blanton. Does Bell's Inequality Principle rule out local theories of quantum mechanics? In 1935 Albert Einstein and two colleagues, Boris Podolsky and Nathan Rosen (EPR) developed a thought experiment to demonstrate what they felt was a lack of completeness in quantum mechanics. This so-called "EPR paradox" has led to much subsequent, and still on-going, research. This article is an introduction to EPR, Bell's inequality, and the real experiments that have attempted to address the interesting issues raised by this discussion. One of the principal features of quantum mechanics is that not all the classical physical observables of a system can be simultaneously known with unlimited precision, even in principle. Instead, there may be several sets of observables which give qualitatively different, but nonetheless complete (maximal possible) descriptions of a quantum mechanical system. These sets are sets of "good quantum numbers," and are also known as "maximal sets of commuting observables." Observables from different sets are "noncommuting observables". A well known example is position and momentum. You can put a subatomic particle into a state of well-defined momentum, but then you cannot know where it is. It's not just a matter of your inability to measure, but rather, an intrinsic property of the particle. Conversely, you can put a particle in a definite position, but then its momentum is completely ill-defined. You can also create states of intermediate knowledge of both observables: if you confine the particle to some arbitrarily large region of space, you can define the momentum more and more precisely. But you can never know both, exactly, at the same time.

171. Research Experience In Physics & Astronomy For Undergraduates (REU) Research areas in this 10week program for undergraduates include astronomy and astrophysics, biological physics, condensed matter physics, high energy physics, nuclear physics, plasma and laser physics, quantum optics, and physics education. http://www.pas.rochester.edu:80/mainFrame/education/special/specialREU.html

Directors: Priscilla S. Auchincloss and Arie Bodek The Physics and Astronomy Research Experience for Undergraduates (REU) Program is funded by the National Science Foundation to support ten to twelve highly-qualified students to undertake supervised research projects in the Department of Physics and Astronomy, for a period of 10 weeks each summer. Departmental faculty conduct research in diverse experimental and theoretical areas, including Biological Physics Condensed Matter Physics High Energy Physics Nuclear Physics ... Quantum Optics , and Physics Education. Each summer, the Department's research effort involves approximately 30 undergraduate students, in addition to approximately 120 graduate students, 35 postdoctoral research associates, and 30 regular faculty members. Much of the research performed by past undergraduate research assistants has been published in scientific journals. Many students have also presented their work at national conferences and undergraduate research symposia at the University of Rochester. Program : Over the 10-week summer research period, participants attend a series of informal seminars covering research topics as well as others, such as preparing for graduate school. These seminars are intended to foster discussion among REU students and faculty, and to serve as a basis for further social and scientific interaction. Students whose projects are primarily experimental are encouraged to attend mini-courses in electronics and in machine shop techniques. The core research experience takes place in the context of research groups working at the University's research facilities. Students present their work at an informal symposium at the end of the summer. They are encouraged to work with their research advisers toward completion of publications, submission of abstracts, and presentations of their work at professional and student conferences.

172. PHYSICS PAGES Spacetime dimension, considerations of finite dimensional variants of standard quantum theory, the nature of space and time, multiple concepts of time, all centered on the fundamental problem of quantum gravity. http://graham.main.nc.us/~bhammel/physics.html

Welcome to the Physics Pages "There is no God, and Dirac is his prophet." W. Pauli "It is that the universe is comprehensible at all; that is the mystery." E. Wigner Epitaph seen: "Here lies Schroedinger's cat" Time doesn't exist, a priori; it is generated by the sheer existence of energy, the sine qua non of existence. Metapostulates: As a function of scale, physical reality is, and physical theory should be, described by alternating regimes of chaos and order; at the lowest scale of physical existence, there is chaos and noncomputability. This is essential for the ontological alternations of chaos and order that do exist. Reality seems at all levels of complexity to require a randomizer of some sort. The fundamental level of reality must contain such a randomizer, and a "Quantum Principle" (Q) must be present as that randomizer. The fundamental level is small, local, and consistant with Q. All Q-type formalisms suggest Lie algebraic structures. The Problem: Define a local Q structure that is Lie algebraic in nature, that gives rise to both the the structure of QM embodied in the Heisenberg algebra, and also to the relational structure embodied in a "Relativistic Principle" R, of which we have two, Special Relativity (SR) and General Relativity (GR), the latter extending SR to include gravity.

Bruce Harvey 's Alternative Physics site New:- A Classical Quantum Theory New:- The classical Atom Summary I believe that subtle errors in 19th Century Physics have caused a build up of cumulative errors until physics now out-weirds science fiction. This is my attempt to find the Unified Laws of Physics I have a consistent theory which explains the phenomena of Electromagnetism, Newtonian Mechanics and Gravity. (In paper 5 , I use Classical physics to account for the so called relativistic effects of the increase in mass, the Lorentz contraction and the slowing of clocks which SR accounts for. I also account for the effects of the slowing of clocks and gravitational red-shift by gravitational potential and the bending of light by gravity.) We start with the Pure Charge Model of Matter . This theory looks at a universe constructed of nothing but space and sees how electrons and quarks could be formed and used as basic building blocks for matter. Such a model exhibits inertial and gravitational properties identical to the real universe. Newtons Laws of Motion can be derived from the basic properties of space and the nature of pure charges.

Caroline Thompson's Physics Created December 19, 2003, based on material from http://www.aber.ac.uk/~cat Updated May 29, 2004 Email: ch.thompson1@virgin.net This site is about what is wrong with Fundamental Physics. It started with the discovery that we have been misled. We have been told that experiments agree with all the predictions of quantum theory, including those that involve the impossible - the Bell test experiments , that are supposed to show totally incomprehensible effects of separated particles on each other. I have looked at the evidence. The "loopholes" that they know are present are large enough to allow for perfectly straightforward explanations, with no sign of "non-locality". I am led to suggest that perhaps there is other currently-accepted "evidence" for both quantum theory and Einstein's relativity theories that needs re-investigation. (There is! See Forgotten History .) I am not talking of "re-interpretation", but of recognising that if we want to
