Sandia’s 20 year experience in building and testing ion traps has culminated in its latest offering: the Enchilada Trap.

Sandia National Laboratories revealed the Enchilada Trap, a groundbreaking ion trap central to some quantum computers, in a press release.

This innovative device promises to reshape the landscape of quantum computing, providing researchers with a potent tool to explore the experimental and transformative field of quantum computation.

This research topic consists of 148 articles on various aspects of brain augmentation contributed by more than 600 authors. At the time of writing, the articles have been viewed online more than 1.3 million times and received plentiful citations in the scientific literature. The topic won the 2017 Frontiers Spotlight Award.

The topic theme, “Augmentation of brain function,” is an umbrella term for the approaches from different disciplines, aimed at the improvement of brain performance in both healthy people and patients suffering from neurological disabilities. Functions of the brain that scientists hope to augment belong to sensory, motor and cognitive domains. Brain enhancements could be achieved pharmacologically or using neurostimulation. Functional improvements can be also achieved with brain training techniques that employ modern technologies like computer games and virtual reality. Furthermore, brain performance can be augmented using brain-machine interfaces (BMIs), the pathways that connect neuronal circuits to external assistive devices, such as limb prostheses, exoskeletons, and communication aids. In addition to sending commands to external devices, BMIs can enable bidirectional communications, where artificial sensory signals are delivered to the brain while information is being decoded from neural recordings.

Even though many of the brain-augmenting ideas sound like science fiction, the topic authors feel optimistic about most of them. The overall consensus is that brain performance can be improved with artificial components, and this approach will lead to practical applications in the not-too-distant future. Many of the techniques covered in the topic, for example BMIs and noninvasive stimulation, have already experienced an explosive development. While expectations are high for the augmentation approaches, philosophers are warning about the ethical issues related to technologies that interfere with the mind, possibly in unpredictable ways. Although some of these concerns seem far-fetched, it is important that ethical standards are kept high as these revolutionary brain-augmenting methods are being developed.

Quantum computing, just like traditional computing, requires a method to store the information it uses and processes. In the computer you’re using right now, information—whether it be photos of your dog, a reminder about a friend’s birthday, or the words you’re typing into your browser’s address bar—must be stored somewhere. Quantum computing, a relatively new field, is still exploring where and how to store quantum information.

As the name implies, Nature Physics is a peer-reviewed, scientific journal covering physics and is published by Nature Research. It was first published in October 2005 and its monthly coverage includes articles, letters, reviews, research highlights, news and views, commentaries, book reviews, and correspondence.

The Defense Advanced Research Projects Agency (DARPA) has announced a new program it says will develop synthetic metamaterials that could lead to breakthroughs in quantum computing and information science.

Called the Synthetic Quantum Nanostructures program, or SynQuaNon, the new DARPA initiative “aims to address this challenge with a fundamental science effort that seeks to develop synthetic metamaterials to enable enhanced functionalities and novel capabilities,” read a statement issued by the agency this week.

The program aims to produce a range of new quantum materials that will have a variety of uses in quantum computing and other information science applications.

These waves can reach heights comparable to stacking three suns on top of each other.

Astronomers have discovered a strange star system with “monster” tidal waves breaking on one of its stars. Astrophysicists from the Center for Astrophysics | Harvard & Smithsonian (CfA) developed new computer models to better understand the impact of huge surface waves.

The new models reveal “titanic waves” created by the tides of a smaller companion star to be repeatedly crashing on the colossal star in the system. This phenomenon has never been detected on a star, making it a significant discovery.

Practical applications for quantum entanglement have already been proposed, as entangled particles have been suggest for use in powerful quantum computers and “impossible” to crack networks. Now, it seems quantum entanglement may be linked to wormholes.

We often believe computers are more efficient than humans. After all, computers can complete a complex math equation in a moment and can also recall the name of that one actor we keep forgetting. However, human brains can process complicated layers of information quickly, accurately, and with almost no energy input: recognizing a face after only seeing it once or instantly knowing the difference between a mountain and the ocean.

These simple human tasks require enormous processing and energy input from computers, and even then, with varying degrees of accuracy.

Creating brain-like computers with minimal energy requirements would revolutionize nearly every aspect of modern life. Quantum Materials for Energy Efficient Neuromorphic Computing (Q-MEEN-C)—a nationwide consortium led by the University of California San Diego—has been at the forefront of this research.

Researchers have developed an easy-to-build, low-cost 3D nanoprinting system that can create arbitrary 3D structures with extremely fine features. The new 3D nanoprinting technique is precise enough to print metamaterials as well as a variety of optical devices and components such as microlenses, micro-optical devices and metamaterials.

“Our system uses a two-step absorption process to realize 3D printing with accuracy reaching the nanometer level, which is suitable for commercial manufacturing,” said research team leader Cuifang Kuang from the Zhejiang Lab and Zhejiang University, both in China. “It can be used for a variety of applications such as printing micro or nanostructures for studying biological cells or fabricating the specialized optical waveguides used for virtual and augmented reality devices.”

Conventional high-resolution 3D nanoprinting approaches use pulsed femtosecond lasers that cost tens of thousands of dollars. In Optics Letters, Kuang and colleagues describe their new system based on an integrated fiber-coupled continuous-wave laser diode that is not only inexpensive but also easy to operate.
