While the federal sequester threatens to starve American science of billions of dollars, here’s a reminder of the achievements of taxpayer-funded innovation. For the first time this year, the U.S.

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

The German physicist Werner Heisenberg, who helped to craft the mathematics behind quantum mechanics in 1925, and his mentor, Danish physicist Niels Bohr, got around the alien wave–particle duality ...

Scientists have finally uncovered a quantum counterpart to Carnot’s famed second law, showing that entanglement—once thought stubbornly irreversible—can be shuffled back and forth without loss if you ...

Quantum physicist Ronald Walsworth is a busy guy. Over the years he has founded a number of startup technology companies, including several in the biomedical field. His name is on a number of patents ...

In a Caltech lab, a computer screen showed thousands of tiny points of light—each one a single atom, held in place by laser beams. This striking image revealed 6,100 stable quantum bits, or qubits. It ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Markus Pflitsch, CEO and Founder of Terra Quantum, is a dedicated quantum physicist, senior financial executive and deep tech entrepreneur. For millennia, global power hinged on geography. From ...

These five quantum computing exchange-traded funds, or ETFs, offer the opportunity to buy into one of the most intriguing emerging technologies in the world. You don’t need to be a quantum physicist ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.
