A study led by the University of Oxford has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the “reality gap”: the difference between predicted and observed behavior from quantum devices. The results have been published in Physical Review X.

Quantum computing could supercharge a wealth of applications, from climate modeling and financial forecasting to drug discovery and artificial intelligence. But this will require effective ways to scale and combine individual quantum devices (also called qubits). A major barrier against this is inherent variability, where even apparently identical units exhibit different behaviors.

Functional variability is presumed to be caused by nanoscale imperfections in the materials from which quantum devices are made. Since there is no way to measure these directly, this internal disorder cannot be captured in simulations, leading to the gap in predicted and observed outcomes.

In recent years, engineers have developed a wide range of robotic systems that could soon assist humans with various everyday tasks. Rather than assisting with chores or other manual jobs, some of these robots could merely act as companions, helping older adults or individuals with different disabilities to practice skills that typically entail interacting with another human.

Researchers at Nara Institute of Science and Technology in Japan recently developed a new robot that can play video games with a human user. This robot, introduced in a paper presented at the 11th International Conference on Human-Agent Interaction, can play games with users while communicating with them.

“We have been developing robots that can chat while watching TV together, and interaction technology that creates empathy, in order to realize a partner robot that can live together with people in their daily life,” Masayuki Kanbara, one of the researchers who carried out the study, told Tech Xplore. “In this paper, we developed a robot that plays TV games together to provide opportunities for people to interact with the robot in their daily lives.”

Jan 9 (Reuters) — Microsoft (MSFT.O) has worked with a U.S. national laboratory to use artificial intelligence to rapidly identify a material that could mean producing batteries that require 70% less lithium than now, the company said on Tuesday.

The replacement of much of the lithium with sodium, a common element found in table salt, still needs extensive evaluation by scientists at Pacific Northwest National Laboratory (PNNL) in Richland, Washington to determine whether it will be suitable for mass production.

“Something that could have taken years, we did in two weeks,” Jason Zander, an executive vice president at Microsoft, told Reuters. “That’s the part we’re most excited about. … We just picked one problem. There are thousands of problems to go solve, and it’s applicable to all of them.”

Using a spectral synthesis code designed to simulate conditions in interstellar matter, astronomers have explored a faint tidal disruption event (TDE) designated iPTF16fnl. Results of the study, published Dec. 29 on the pre-print server arXiv, deliver important insights into the properties of this TDE.

TDEs are astronomical phenomena that occur when a star passes close enough to a supermassive black hole and is pulled apart by the black hole’s tidal forces, causing the process of disruption. Such tidally-disrupted stellar debris starts raining down on the black hole and radiation emerges from the innermost region of accreting debris, which is an indicator of the presence of a TDE. All in all, the debris stream-stream collision causes an energy dissipation, which may lead to the formation of an accretion disk.

Therefore, TDEs are perceived by astronomers as potentially important probes of strong gravity and accretion physics, providing answers about the formation and evolution of supermassive black holes.

After a decade studying thousands of supernovae, astronomers are still perplexed by the enigma that led Einstein to his ‘greatest mistake’

Scientists overcame a limitation in graphene to harness the material as a working semiconductor at terahertz frequencies with 10 times the mobility of silicon.

As climate change continues to ravage the planet, coastal cities are at the highest risk due to coastal flooding attributed to sea level rise. According to the National Oceanic and Atmospheric Administration, approximately 127 million people in the United States alone live in coastal counties, or almost 40 percent of the entire population. Therefore, steps to protect coastal communities are of the utmost importance to mitigate the long-term impacts of climate change.

Strengthening coastal defenses from rising seas levels is what a groundbreaking study known as the PIONEER project, which is funded by the Engineering and Physical Sciences Research Council, hopes to address as scientists estimate coastal sea levels in the United States will experience the same sea level rise by 2050 that was experienced between 1920 and 2020, between 0.82 to 0.98 inches (0.25 to 0.30 meters).

“This is an interesting study because it combines, probably for the first time, the interactions for the effect of the water flooding on soils and, subsequently, on shoreline protective structures,” said Dr. Sherif Abdelaziz, who is an associate professor in the Charles E. Via, Jr. Department of Civil and Environmental Engineering, and one of many collaborators on the PIONEER project. “We will be able to assess how all these factors interact together so we can better design our shoreline protective structures to sustain the increasing intensity of waves and floods.”

Honda Zero includes two concepts: the sleek, sedan-like Saloon, and a boxier big-booty van-thing called the Space-Hub.
