A simpler way to connect quantum computers (01/09/2023)

Researchers have a new way to connect quantum devices over long distances, a necessary step toward allowing the technology to play a role in future communications systems.

Researchers observe strongest quantum contextuality in single system (01/09/2023)

A team led by Prof. Li Chuanfeng and Prof. Xu Jinshi from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with Prof. Chen Jingling from Nankai University and Prof. Adán Cabello from the University of Seville, studied the single-system version of multipartite Bell nonlocality, and observed the highest degree of quantum contextuality in single system. Their work was published in Physical Review Letters.

Researchers design a new way to capture and recycle carbon dioxide from industrial emissions (31/08/2023)

Carbon capture is a promising method to help slow climate change. With this approach, carbon dioxide (CO2) is trapped before it escapes into the atmosphere, but the process requires a large amount of energy and equipment. Now, researchers reporting in ACS Central Science have designed a capture system using an electrochemical cell that can easily grab and release CO2. The device operates at room temperature and requires less energy than conventional, amine-based carbon-capture systems.

Researchers demonstrate high-fidelity transmission of information via novel electronic-optical system (30/08/2023)

Transferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater communication, and medical devices. Nevertheless, unpredictable, unknown phase perturbations or random diffusers within the optical path pose great challenges, limiting the high-fidelity transmission of optical data in free space. Adaptive optics presents a potential solution that can correct for random distortions dynamically; however, spatial light modulators and iterative feedback algorithms employed inevitably increase both cost and complexity.

Physicists develop series of quality control tests for quantum computers (30/08/2023)

Quantum technologies—and quantum computers in particular—have the potential to shape the development of technology in the future. Scientists believe that quantum computers will help them solve problems that even the fastest supercomputers are unable to handle yet. Large international IT companies and countries like the United States and China have been making significant investments in the development of this technology. But because quantum computers are based on different laws of physics than conventional computers, laptops, and smartphones, they are more susceptible to malfunction.

Chemists turned plastic waste into tiny bars of soap (28/08/2023)

A new technique could one day help turn plastic waste into valuable raw materials

Scientists Invent New Glass With Supreme Toughness (26/08/2023)

Scientists have produced an oxide glass with unprecedented toughness. Under high pressures and temperatures, they succeeded in paracrystallizing an aluminosilicate glass: The resulting crystal-like structures cause the glass to withstand very high stresses and are retained under ambient conditions. Paracrystallization thus proves to be a promising process for producing extremely break-resistant glasses.

Paper drinking straws may be harmful and may not be better for the environment than plastic versions, researchers warn (24/08/2023)

"Eco-friendly" paper drinking straws contain long-lasting and potentially toxic chemicals, a new study has concluded.

New technique harvests antioxidants from olive oil processing waste (22/08/2023)

A great deal of peel, pulp and stone waste is constantly being generated in the production of olive oil. And while that waste is often just dumped or incinerated, it could soon be used as a source of valuable antioxidants.

Waste coffee grounds make concrete 30% stronger (22/08/2023)

Researchers have found that concrete can be made 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste product produced in huge amounts that usually ends up in landfill. The method also reduces the use of natural resources like sand, further contributing to a greener circular economy approach to construction.
