Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

New theoretical research proves that machine learning on quantum computers requires far simpler data than previously believed. The finding paves a path to maximizing the usability of today’s noisy, ...

A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...

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 ...
