On Friday, representatives of more than 60 nations will convene in Versailles, France, to approve a new definition for the kilogram. Since the 19th century, scientists have based their definition of the fundamental unit of mass on a physical object – a shining platinum iridium cylinder stored in a locked vault in the bowels of the International Bureau of Weights and Measures (BIPM) in Sevres, France. A kilogram was equal to the heft of this aging hunk of metal, and the cylinder, by definition, weighed exactly a kilogram. If … [Read more...] about For decades, the kilogram was based on a hunk of metal. The world just redefined it using quantum physics.

The coldest place in Oregon isn't at the bottom of Crater Lake or on a windswept peak atop Mount Jefferson. It's inside a windowless room in Hillsboro, deep within an Intel research lab. There, engineers are doing something strange. They're freezing computer chips to 460 degrees Fahrenheit below zero, colder than deep space, to simulate the quantum structure of the universe. At such extreme temperatures these remarkable chips, called qubits, enable scientists to peer into the complex, uncertain interaction of particles at the atomic level - an unseen world in which seemingly contradictory results can exist simultaneously, a place where simply observing an interaction can change it. Or wreck it altogether. "Quantum - it's something weird," said Mike Mayberry, Intel's chief technology officer and general manager of Intel Labs. Intel and its rivals are racing to develop quantum computers that could vastly exceed the capabilities of the conventional computers we have today. But it will be … [Read more...] about Intel plots a weird, spooky future in quantum computing
/EIN News/ -- Dublin, Aug. 10, 2018 (GLOBE NEWSWIRE) -- The "Quantum Computing: Technologies and Global Markets to 2022" report has been added to ResearchAndMarkets.com's offering.

The report includes: 35 data tables Detailed study and an industry analysis of the global markets and technologies for quantum computing Analyses of global market trends with data from 2016, forecasts for 2017 to 2027, and projections of compound annual growth rates (CAGRs) through 2027 Identification of the quantum computing technologies and products with the greatest commercial potential Segmentation of the global quantum computing market by technology type, end use, application sector, and geographical region Technological … [Read more...] about Quantum Computing: Technologies & Global Markets to 2027
Rainer Blatt, Ph.D, a scientific director of the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences in Innsbruck, Austria, delivered a presentation at Colorado State University, focusing on quantum computing and quantum technologies for the information age. “He’s a world leader in experimental quantum computing,” said Dr. William Fairbank, Ph.D, who co-ran Blatt’s presentation along with Siu Au Lee, Ph.D. “Quantum computers are just beginning to get to the stage where they might begin to compete with classical computers. This is an intriguing development for the future.” During his hour-long presentation, Blatt focused on topics such as advances of computer technology, quanta and quantum physics, quantum bits, register and gates, superposition, entanglement, computing with atoms and laser beams and current quantum computations. Blatt began his presentation by delving into the history of visionary computer … [Read more...] about Dr. Rainer Blatt gives presentation on quantum computing
STOCKHOLM A French-American duo shared the 2012 Nobel Prize in physics Tuesday for experiments on quantum particles that have already resulted in ultra-precise clocks and may one day help lead to computers many times faster than those in use today. Serge Haroche of France and American David Wineland showed in the 1990s how to observe individual particles while preserving their bizarre quantum properties, something that scientists had struggled to do before. A quantum particle is one that is isolated from everything else. In this situation, an atom or electron or photon takes on strange properties. It can be in two places at once, for example. It behaves in some ways like a wave. But these properties are instantly changed when it interacts with something else, such as when somebody observes it. Working separately, the two scientists, both 68, developed "ingenious laboratory methods" that allowed them to manage and measure and control fragile quantum states, the Royal Swedish Academy of … [Read more...] about CBS News Logo American, Frenchman share Nobel physics prize
