Quantum sensing has long promised exquisite sensitivity, but in the real world, environmental noise usually buries the very signals researchers want to see. A new experiment using just three trapped ...

The first digital “quantum simulator” based on trapped ions has been built by physicists in Austria. The system, developed by Ben Lanyon and colleagues at the University of Innsbruck, comprises a ...

Even with regular brushing, teeth can become stained from genetic factors or consuming foods and drinks like tomatoes and coffee. Chemical whiteners can help, but they can also damage teeth in the ...

Renewable energy and electric cars are driving demand for batteries with denser energy storage than standard lithium-ion batteries. Ions that can carry more than one charge, such as calcium and ...

Researchers at The Hong Kong University of Science and Technology have developed a new type of calcium-ion battery that could challenge lithium-ion technology by improving stability and performance.

Concerns about the security and sustainability of battery materials being utilized are growing. The long-term use of lithium in energy storage devices is in danger due to looming worries about ...
