Olival Freire Jr is a professor of physics and the history of physics at the Federal University of Bahia, Brazil. What makes matter stable? Why are atoms as they are? Why do different materials vary ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on a miniaturized platform. This advance could help move quantum random number ...

Quantum physicist Vlatko Vedral proposes a radical new vision of reality, one in which observers don’t exist, there are no particles and there is no space or time. Instead, for Vedral, quantum numbers ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

In the 1960s, a group of physicists and historians began a massive project meant to catalogue and record the history of quantum physics. It was called Sources for History of Quantum Physics (SHQP). As ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out. But new in the way they share ...
