Scientists at the University of Texas at Austin have developed a new superconducting material that might allow the construction of quantum computers that are more resistant to outside noise, such as electromagnetic interference.
This is the first of a three-part series on general relativity.
In November 1915, Albert Einstein stood before his colleagues in the Prussian Academy of Sciences and unveiled a set of equations that would forever change the way we see the universe. The Theory of General Relativity, Einstein's description of gravity, explained the motions of everything we see in the universe.
Physicists Xiaoqin "Elaine" Li, Gennady Shvets and their colleagues have been exploring new ways to manipulate light on the nanoscale. In a paper published this week in the journal Proceedings of the National Academy of Sciences, they describe work that could lead to better biological sensors and improved devices for optical communications and computing.
As traditional electronics begin to reach their physical limits of compactness and speed, scientists and engineers are looking for new ways to stay on track with Moore's Law. One possible solution is to develop spintronics, devices that use a property of electrons known as spin to represent the 0's and 1's in computers. A class of materials called topological insulators (TIs) might have the right properties for spintronics, but since they were discovered less than a decade ago, scientists still know little about their properties.
This month marks the 50th Anniversary of Moore's Law, an observation that every couple of years, computer chip manufacturers manage to squeeze twice as many transistors onto a computer chip. Because transistors are the tiny on-off switches that perform calculations and temporarily store information, Moore’s Law also embodies the exponential increase in raw computing power that has unleashed a blizzard of tech innovations.
Scientists at The University of Texas at Austin and Princeton University have observed an exotic particle that behaves simultaneously like matter and antimatter, a breakthrough that could eventually enable powerful computers based on quantum mechanics.
Topological insulators, a state of matter that was only discovered in the past decade, may enable dramatic advances in quantum computing and spintronics.
Physicist-chemist received the award for his computational applications of quantum theories to understand and predict material properties.
