... simulation of quantum systems. Chemistry and nanotechnology heavily rely on understanding of these systems, however classical computers can’t simulate them in an efficient manner. But quantum computers could simulate quantum physics processes exponentially faster and would be extremely useful for creating new drugs and materials and for researching particle interaction in particle accelerators. Also quantum computers would perform better in solving optimization problems, when you need to find the best solution out of a range of possible solutions. However it is hard to predict how we will use these computers in the future. I mean for example even the creators of the first digital computers couldn’t predict that in the future we would use them for playing games or browsing social networks. CURRENT ACHIEVEMENTS IN QUANTUM COMPUTING Now lets talk about current advancements in quantum computing. The idea to build a quantum computer first appeared 1980s however the research of these machines is still in it’s infancy. Various quantum research centers all around the world are trying out different methods to realize qubits and have built several prototypes however there is no unified quantum computer model like for example all of the classical computer technology is entirely based on transistor systems. Several most popular quantum computer architectures are as follow: * Based on stray nitrogen atoms in a diamond crystal structure. One of the bigger advantages of this......

...QUANTUM ELECTRODYNAMICS What is quantum electrodynamics? Sociology Anna C Jean – Guillaume Martin LCSW March 7, 2015 Professor Dr. Beverly Jackson Quantum electrodynamics (QED): Is the e area of physics devoted to the study of the interaction of matter (quantum particles) and light. It generally concerns itself with the wave (or field) aspects of nature. At the level of the quantum realm, QED demonstrates that everything is connected. The world is a vast web of relationships, with everything affecting everything else. The brain, blood, and bone of the body give way to invisible forces, fields, and particles whose interactions underlie not only the human body but all of matter. Molecules give way to atoms that dissolve into subatomic particles, so that our bodies are governed not only by the laws of everyday chemistry but also by the paradoxical principles of the physical body. History shows that most truly fundamental leaps forward in scientific understanding are shunned at first. Truly new insights are sometimes too radical an overturning of accepted theory or too threatening to business or academic interests to be evaluated impartially. You have only to think of germ theory, tectonic plate theory, quantum electrodynamics, and string theory to know that even ideas that are accepted widely in our day were dismissed as crackpot ideas by a previous generation of scientists. Over the years, as physicists’ explored wave-particle duality, the study of quantum...

In fact, now that you know an atom isn t just a nucleus with electrons looping around it, I guess you re wondering what it looks like. Instead of having a fixed place for the electrons to be, quantum physics gives us a statistical probability of the electron s location at any one moment.

That changed in 2011, with the publication of a theorem about quantum measurements that seemed to rule out the wavefunction-as-ignorance models. On closer inspection, however, the theorem turned out to leave enough wiggle room for them to survive. Nonetheless, it inspired physicists to think seriously about ways to settle the debate by actually testing the reality of the wavefunction. Maroney had already devised an experiment that should work in principle, and he and others soon found ways to make it work in practice, , . The experiment was carried out last year by Fedrizzi, White and others.

But this is where the debate gets stuck. Which of quantum theory's many interpretations — if any — is correct? That is a tough question to answer experimentally, because the differences between the models are subtle: to be viable, they have to predict essentially the same quantum phenomena as the very successful Copenhagen interpretation. Andrew White, a physicist at the University of Queensland, says that for most of his 20-year career in quantum technologies “the problem was like a giant smooth mountain with no footholds, no way to attack it”.

The all-pervading ether acts in the physical world as a quantum realityfilled with an infinite number of forms that give ril and real particles,and banks of energy from which mass, motion, charge, spin, energy, andwhatever else is born. From this all-permeating ether also comes theworld of the spiritually formed beings. From what `Abdu'l-Bahá says,ethereal matter is the basic substance and generator of all createdthings, both material and spiritual. This ether, according to Bahá'u'lláh,has "the closest likeness to the human spirit." (Tablets, p 146)

Uncertainty Principle and Quantum Mechanics Essays ‘uncertainty’ occurs in several different meanings in the physical literature

The "void" or "nothingness" of quantum physics is distinctly differentthan the "Void" of Buddhism. The "void" or "nothingness" of quantumphysics is like a gigantic "vacuum fluctuation" from which physiciststhink the universe came about. If God created the universe from a void ornothingness, then we should carefully look into the properties of that"void or nothingness" from which our being came. The vacuum is just thephysicist's word for "void" or "nothingness." Over 100 years ago, thisempty void was considered to be filled with a thin, transparent mediumcalled ether through which light waves and electromagnetic waves, ingeneral, are propagated. This seemed to be natural to physicists, sincewaves are usually observed as vibrations of something. For example, sound waves are vibrations of air, water and solids.

These seven short lessons guide us, with simplicity and clarity, through the scientific revolution that shook physics in the twentieth century and still continues to shake us today. In this beautiful and mind-bending introduction to modern physics, Carlo Rovelli explains Einstein's theory of general relativity, quantum mechanics, black holes, the complex architecture of the universe, elementary particles, gravity, and the nature of the mind. In under eighty pages, readers will understand the most transformative scientific discoveries of the twentieth century and what they mean for us. Not since Richard Feynman's celebrated best-seller has physics been so vividly, intelligently and entertainingly revealed.
