Researchers Observe Electronic Structure of Iron-Based Superconductors at the Atomic Scale

Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported in the Feb. 24 online edition of the journal Nature Physics.

ESS Granted Patent for Neutron Detector Components with Boron Carbide Layers

The European Spallation Source (ESS) in Lund has been granted its first patent in collaboration with researchers at Linköping University. The innovation solves a significant technological challenge faced by many research facilities world-wide, and secures high-class experimental opportunities at the future ESS. It can also be developed for commercial production.

Efficient Triangles Finding Algorithm Holds Potential for Quantum Computing

Two papers about minimising effort took CQT researchers to the prestigious ACM-SIAM SODA conference in New Orleans in January. The CQT computer scientists and their collaborators set bounds on the amount of work that needs to be done to solve two different problems.

MSU to Celebrate Centennial of Einstein's Theory of General Relativity

Montana State University will host one of the world's first events to celebrate the centennial of Einstein's theory of General Relativity, its final prediction and the impending detection of gravitational waves.

Network of Small Quantum Computers Can Implement Quantum Algorithms

A quantum computer doesn't need to be a single large device but could be built from a network of small parts, new research from the University of Bristol has demonstrated. As a result, building such a computer would ...

Historic Cyclotron Returns to Berkeley Lab after 75 Years

Seventy-five years after one of the world’s first working cyclotrons was handed to the London Science Museum, it has returned to its birthplace in the Berkeley hills, where the man who invented it, Ernest O. Lawrence, helped launch the field of modern particle physics as well as the national laboratory that would bear his name, Lawrence Berkeley National Laboratory.

Researchers Insert Sophisticated Light Resonators inside Living Cells

If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host.

Higgs Boson Symposium at AAAS Annual Meeting

Get the latest on the science news that topped multiple “Top-10” lists for 2012—the discovery of a new elementary particle that fits all descriptions of the long-sought Higgs boson. Physicists from ATLAS and CMS, the two experiments at the Large Hadron Collider (LHC) that saw telltale signs of the new particle in 2011—and have been gathering more data since—will describe details of the search, the latest findings, and future directions for research on the Higgs at the annual meeting of the American Association for the Advancement of Science (AAAS) in Boston, MA.

Nebraska-Lincoln Physicist Discusses Attosecond Science in Chemical, Molecular Imaging, Spintronics and Energy Science

One-billionth of a billionth of a second. That's the scale – an attosecond – at which scientists seek to image and control electronic motion in matter. Its natural time scale.

Attosecond Science May Help Control Quantum Nature of the Electron

In the blink of an eye, more attoseconds have expired than the age of Earth measured in – minutes. A lot more. To be precise, an attosecond is one billionth of a billionth of a second. The attosecond timescale is where you must go to study the electron action that is the starting point of all of chemistry. Not surprisingly, chemists are most eager to explore it with X-rays, the region of the electromagnetic spectrum that can probe the core electrons of atoms, the electrons that uniquely identify atomic species.

IQC Quantum Researcher to Participate in AAAS Annual Meeting

Quantum information processing promises not only breakthroughs for computing, communications and cryptography, but it can also help us devise tools for navigating and controlling the nano-scale world. Sensors that operate according to quantum mechanics may achieve sensitivity, selectivity, precision and robustness far beyond their classical counterparts.

Study on Dopant Cobalt Atoms May Lead to New Types of Superconductors

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into “superconductors” able to carry electrical current with no energy loss—an enormously promising idea for new types of zero-resistance electronics and energy-storage and transmission systems.

Multi-Particle Quantum Walk for Universal Computation

The IQC team of Andrew Childs (Associate Professor of Combinatorics and Optimization), David Gosset (Post-Doctoral Fellow) and Zak Webb (PhD student) have proposed a new universal computational model. This model has the potential to become an architecture for a scalable quantum computer without the need to actively manipulate qubits during the computation. The team’s findings will be published in the February 15, 2013 issue of Science.

Researchers Reverse Quantum Measurement Using Quantum Error Correction Protocol

A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory – at first glance. The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer.
