Refrigerator for quantum computers Quantum physicist Mikko Möttönen at Aalto University in Finland and his team have invented a quantum-circuit refrigerator, meant to reduce errors in quantum computing. The research results suggest how harmful errors in quantum computing can be removed — a new twist towards a functioning quantum computer. The team reminded that quantum computers use... » read more

Infrared links for data centers Researchers at Penn State, Stony Brook University and Carnegie Mellon University developed a free space optical link for communication in data centers using infrared lasers and receivers mounted on top of data center racks. According to Mohsen Kavehrad, professor of electrical engineering at Penn State, "It uses a very inexpensive lens, we get a very narrow... » read more

Legal Back in 2013, Synopsys filed suit against ATopTech for copyright infringement. The courts found in favor of Synopsys and ATopTech was damages were set at a little over $30M. With appeals unsuccessful, ATopTech announced that it has filed a voluntary petition under Chapter 11 of the Bankruptcy Code and has filed a motion to sell its businesses using a stalking horse bidder (an initial b... » read more

Getting to 1nm Researchers at the Lawrence Berkeley National Laboratory, UC Berkeley, University of Texas at Dallas, and Stanford University created a transistor with a working 1nm gate from carbon nanotubes and molybdenum disulfide (MoS2). "The semiconductor industry has long assumed that any gate below 5 nanometers wouldn't work, so anything below that was not even considered," said fir... » read more

Mixing topology, spin MIT researchers are studying new compounds, such as topological insulators (TIs), which support protected electron states on the surfaces of crystals that silicon-based technologies cannot as part of the pursuit of material platforms for the next generation of electronics. They report new physical phenomena being realized by combining this field of TIs with the subfiel... » read more

Controlling autonomous vehicles in extreme conditions In an approach that could help make self-driving cars of the future safer under hazardous road conditions, a Georgia Institute of Technology research team devised a way to help keep a driverless vehicle under control as it maneuvers at the edge of its handling limits. According to the team comprised of researchers from Georgia Tech’s D... » read more

Digital storage in DNA Computer scientists and electrical engineers from University of Washington and Microsoft detailed one of the first complete systems to encode, store and retrieve digital data using DNA molecules, which can store information millions of times more compactly than current archival technologies. Progress in DNA storage has been rapid: in 1999, the state-of-the-art in DN... » read more

Increasing optical storage capacity with holograms Researchers from the University of Cambridge have developed a new method for making multi-colored holograms from a thin film of silver nanoparticles, which they say could greatly increase the storage capabilities of typical optical storage devices. The interference produced by the interaction of light with the nanoparticles allows the holog... » read more

Optical Metamaterial with a Refractive Index of Zero Most of the time we hear about the need for coherent light sources, such as those produced by lasers, but there may be equal promise looking in the other direction. Quantum processors promise to be many times faster and more powerful than today’s supercomputers, but to get to that point they will need fast and efficient multi-directiona... » read more
