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

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

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

Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states exist in ...

Amid some scepticism, many say the machines can now achieve results beyond the capability of traditional computers ...

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...

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

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...
