Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope ...

A new experiment confirms that angular momentum conservation holds even when a single photon is split into two.

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

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 ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

After decades of theory, prototypes, and incremental progress, quantum computing has entered a new era… The story began in earnest in the early 1980s, when Richard Feynman and Yuri Manin argued that ...

Entangled light proves quantum computers can do what classical methods can't - cut years of work into seconds, an enormous quantum advantage ...
