Computer-Assisted Accelerator Design

Computer-Assisted Accelerator Design

If you walk by room 201 in Building 911 at the U.S. Department of Energy’s Brookhaven National Laboratory, you might think Stephen Brooks is playing a cool new video game. But Brooks is doing important, innovative work. He’s using his own custom designed software to create a 3-D virtual model of the electron accelerator Brookhaven [...]

New ‘Switch’ Could Power Quantum Computing

New ‘Switch’ Could Power Quantum Computing

Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists at MIT and Harvard University have developed a new method for connecting particles — one that could help in the development of powerful quantum computing systems.   The new technique, described in a paper published today in the [...]

Optical Tweezers Split Ultracold Atom Clouds

Optical Tweezers Split Ultracold Atom Clouds

Physicists at New Zealand’s University of Otago have pushed the frontiers of quantum technology by developing a steerable ‘optical tweezers’ unit that uses intense laser beams to precisely split minute clouds of ultracold atoms and to smash them together.   The Otago researchers’ feat is set to enhance efforts to understand the mysterious ways that [...]

Einstein’s ‘Spooky’ Theory: Quantum Internet?

Einstein’s ‘Spooky’ Theory: Quantum Internet?

Einstein’s skepticism about quantum mechanics may lead to an ultra-secure Internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.   Associate Professor Margaret Reid from Swinburne’s Centre for Quantum and Optical Science said Einstein’s reservations about quantum mechanics were highlighted in a phenomenon known as “‘spooky’ action at a [...]

Electronics Based On a 2-D Electron Gas

Electronics Based On a 2-D Electron Gas

Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas [...]

‘Quantum Droplet’ in Semiconductor Discovered

‘Quantum Droplet’ in Semiconductor Discovered

JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle — a handful of smaller particles that briefly condense into a liquid-like droplet.   Quasiparticles are composites of smaller particles that can be created inside solid materials and act together in a predictable way. A simple example is [...]

A New Laser for a Faster Internet

A New Laser for a Faster Internet

A new laser developed by a research group at Caltech holds the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network — the backbone of the Internet.   The study was published the week of February 10-14 in the online edition of the Proceedings of the National Academy [...]

Filleting Robot to Help the Norwegian Fishing Industry

Filleting Robot to Help the Norwegian Fishing Industry

A newly developed white fish filleting machine could give this Norwegian industry a much-needed boost.   Unlike farmed salmon, white fish varies greatly in size and weight. This means that until now, no one has been able to develop a machine that can fillet these fish. However, there is now a filleting machine that could [...]
