In the end, the measured phase of the quantum wave sits 2.5 percent from the theoretical prediction. The result, the team argues, is a checkpoint on the border between Einstein’s relativity and ...

Until now, demonstrating entanglement required direct interaction between quantum systems; this work shows it’s possible via ...

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

In 1935, Austrian physicist Erwin Schrödinger proposed the 'cat in a box' thought experiment to critique quantum mechanics theory. Courtesy of Getty Images Bank According to quantum mechanics, ...

Quantum mechanics powers lasers and precision measurements. A century-spanning perspective examines those successes and the ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or ...

IntroductionIn contexts like electrons, quantum spin or pairs of quantum entanglement are often expressed as plus or minus ...

Quantum mechanics represents one of the most successful scientific theories of the twentieth century, describing the behaviour of matter and energy at atomic and subatomic scales. Central to its ...

A BOAT trip on Lake Zurich seemed like the perfect way to unwind after intense discussions about the hot topic of the moment, quantum theory. Appropriate, too, given that all the physicists present ...
