... 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”.
