The shell of a water/glycerol gas marble (bubble) remains liquid and spherical even after 101 days, and it reacts as a liquid film when punctured. These human-made bubbles could be used to create stable foams. (credit: A. Roux et al., 2022) ...
Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits -- and thus, in turn, particularly efficient quantum computers.

The goal of nuclear physics is to describe all matter from its simplest building blocks: quarks and gluons. Found deep inside protons and neutrons, quarks and gluons also combine in less common configurations to make other subatomic particles of...
Researchers have achieved a key milestone toward the development of a fault-tolerant quantum computer. They were able to demonstrate a two-qubit gate fidelity of 99.5 percent -- higher than the 99 percent considered to be the threshold for building...
