Future Affects Past in Quantum World Physicist Kater Murch in his lab with the dilution freezer for the superconducting qubit he uses to explore quantum space. Experiments with the qubit demonstrate that, in the quantum world, the future affects the past. Image: Joe Angeles, WUSTL PhotosWe’re so used to murder mysteries that we don’t even notice how mystery authors play with time. Typically the murder occurs well before the midpoint of the book, but there is an information blackout at that point and the reader learns what happened then only on the last page. 10 Ways the Next Ten Years are Going to be Mind-Blowing We are living in an extremely exciting time in terms of science and technology. Things that have always been considered science fiction are becoming normal day-to-day components of our lives. And while we have been seeing invention after breakthrough over and over in the last couple of decades, this next ten years is going to blow everything else out of the water. The awesome thing about all these scientific discoveries it that they create technology that allows us to make more breakthroughs even faster. Our ability to innovate is increasing exponentially as the years go by.
Evolving Scalable Quantum Computers D-Wave's first generation quantum processors (now being explored in conjunction with Google/NASA as well as Lockheed and USC) are showing encouraging signs of being at a "tipping point" .. matching state of the art solvers for some benchmark problems (and sometimes exceeding them) ... portending the exciting possibility that in a few years D-Wave processors could exceed the capabilities of any existing classical computing systems for certain classes of important problems in the areas of machine learning and optimization. In this lecture, Eric Ladizinsky, Co-Founder and Chief Scientist at D-Wave will describe the basic ideas behind quantum computation , Dwave's unique approach, and the current status and future development of D-Wave's processors. Included will be answers to some frequently asked questions about the D-Wave processors, clarifying some common misconceptions about quantum mechanics, quantum computing, and D-Wave quantum computers.
Scientists squeeze light past quantum limit › News in Science (ABC Science) News in Science Monday, 12 September 2011 Stuart GaryABC Tiny ripples The race to discover gravity waves may be getting closer to the finish line with scientists successfully squeezing light using quantum mechanics. The detection of gravity waves is one of the Holy Grails of astronomy and astrophysics. It will allow researchers to study the inner workings of exploding stars and colliding black holes. Two New Particles Enter the Fold Physicists at the Large Hadron Collider (LHC) have detected two never-before-seen subatomic particles. These particles were predicted by the quark model and estimated to have masses roughly six times that of the proton, but previous experiments have not run at high enough energy to produce these massive particles. The detections offer new precision measurements of the masses, which will place tighter constraints on particle physics theories. Quarks come in three families: up/down, strange/charm, and bottom/top. In 2007, physicists observed the first particle with one quark from each family: , consisting of one bottom, one strange, and one down quark, giving it a negative charge of . However, this is just the lowest mass version of this three-family quark combination.
Africa’s Tech Edge How the continent's many obstacles, from widespread poverty to failed states, allowed African entrepreneurs to beat the West at reinventing money for the mobile age Mike McQuade It’s a painfully First World problem: Splitting dinner with friends, we do the dance of the seven credit cards. No one, it seems, carries cash anymore, so we blunder through the inconvenience that comes with our dependence on plastic.
Google Finds Dwave Quantum annealer is 100 million times faster than a classic single core computer and discusses scaling and improving quantum computers During the last two years, the Google Quantum AI team has made progress in understanding the physics governing quantum annealers. We recently applied these new insights to construct proof-of-principle optimization problems and programmed these into the D-Wave 2X quantum annealer that Google operates jointly with NASA. The problems were designed to demonstrate that quantum annealing can offer runtime advantages for hard optimization problems characterized by rugged energy landscapes. We found that for problem instances involving nearly 1000 binary variables, quantum annealing significantly outperforms its classical counterpart, simulated annealing.
Possibility of cloning quantum information from the past Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU's Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past. It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the paradoxes that would occur if one could travel back in time.
Scientists discover how to turn light into matter after 80-year quest Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago. In just one day over several cups of coffee in a tiny office in Imperial's Blackett Physics Laboratory, three physicists worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934. Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron – the simplest method of turning light into matter ever predicted. The calculation was found to be theoretically sound but Breit and Wheeler said that they never expected anybody to physically demonstrate their prediction. It has never been observed in the laboratory and past experiments to test it have required the addition of massive high-energy particles.
Five "Free Energy" Devices that Could Save You Thousands of Dollars Image credit: www.flickr.com/photos/cr03/42435041 “Free energy” devices are the most important inventions for helping us solve many of our financial problems. Many of these “free energy” generators have the ability to generate energy at a fraction of the cost of traditional energy generators. Imagine having a “free energy” device in your home that generates enough electricity to power all your appliances and electronic devices for the cost of 10 dollars or less per month. How would that change your financial life? Besides helping you save a lot of money from your electricity bill, “free energy” generators can dramatically reduce the cost of goods and services.
